MySQL主從複製.半同步.基於ssL加密複製
MySQL複製的好處
1. 負載均衡html
2. 數據的分佈node
3. 備份的操做mysql
4. 高可用和容錯linux
MySQL複製的原理
1.將master服務器改變的數據記錄到二進制日誌（binary log）中sql
2.slave服務器將master服務器上的二進制日誌經過i/o線程獲取到本身的中繼日誌中（relay-log）數據庫
3.slave服務器經過sql線程讀取中繼日誌，而後將改變的數據寫入到本身的數據庫中 vim
上述圖片爲二進制簡單的複製過程簡介安全
配置注意事項和前提條件
1. master服務器必須開啓二進制日誌服務器
2. master和slave的server-id不能相同網絡
3. 同一個master的多個slave，server也不能相同
4. Binlog_format最好相同 ，不然會致使數據不一致
5. 在slave服務器上配置log-slave-updates=1時，也須要開啓二進制日誌
6. Read_only選項開啓，能夠阻止沒有權限的線程修改數據

OK Filling help tables... OK To start mysqld at boot time you have tocopy support-files/mysql.server to the rightplace for your system PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER ! To do so, start the server, then issue thefollowing commands: ./bin/mysqladmin -u root password'new-password' ./bin/mysqladmin -u root -h node3 password'new-password' Alternatively you can run: ./bin/mysql_secure_installation which will also give you the option ofremoving the test databases and anonymous user created by default. This is strongly recommended for productionservers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; ./bin/mysqld_safe & You can test the MySQL daemon withmysql-test-run.pl cd ./mysql-test ; perl mysql-test-run.pl Please report any problems with the./bin/mysqlbug script! [root@node3 mysql]# service mysqld start Starting MySQL... SUCCESS!
主從複製配置
在master服務器上創建用於slave服務器複製數據的帳戶（最小權限）

2. 在Slave服務器上使用受權用戶鏈接測試
[root@node4 ~]# mysql -ubds -pbudongshu -h192.168.17.15 Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.5.33-log MySQL CommunityServer (GPL) Copyright (c) 2000, 2013, Oracle and/or itsaffiliates. All rights reserved. Oracle is a registered trademark of OracleCorporation and/or its affiliates. Other names may be trademarksof their respective owners. Type 'help;' or '\h' for help. Type '\c' toclear the current input statement. mysql>
3. 修改slave服務器的配置文件
skip_slave_start = 1 read_only = 1 relay_log = relay_log relay_log_index = relay_log.index server-id = 21 #log-bin=mysql-bin #log-bin=mysql-bin [root@node4 ~]# service mysqld restart
4．修改mater服務器的配置文件
log-bin=mysql-bin log_bin_index = msyql_bin.index binlog_format=mixed server-id = 1
5.查看master服務器的二進制日誌和二進制日誌事件位置
mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB |Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000003 | 355 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec)
6.開始在slave服務器同步master服務器的數據
mysql> help change master to MASTER_BIND = 'interface_name' |MASTER_HOST = 'host_name' |MASTER_USER = 'user_name' |MASTER_PASSWORD = 'password' |MASTER_PORT = port_num |MASTER_CONNECT_RETRY = interval |MASTER_HEARTBEAT_PERIOD = interval |MASTER_LOG_FILE = 'master_log_name' |MASTER_LOG_POS = master_log_pos mysql> change master tomaster_host='192.168.17.15',master_user='bds',master_password='budongshu',master_port=3306,master_log_file='mysql-bin.000003',master_log_pos=355; Query OK, 0 rows affected (0.01 sec)
7．啓動slave服務器的複製線程並查看狀態
mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status\G *************************** 1. row*************************** Slave_IO_State: Waiting formaster to send event Master_Host: 192.168.17.15 Master_User: bds Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000003 Read_Master_Log_Pos: 355 Relay_Log_File: relay_log.000002 Relay_Log_Pos: 253 Relay_Master_Log_File: mysql-bin.000003 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 355 Relay_Log_Space: 403 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1 1 row in set (0.00 sec)
mysql> show processlist; +----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+ | Id | User | Host | db | Command | Time | State |Info | +----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+ | 2| root | localhost | NULL |Query | 0 | NULL | show processlist | | 3| system user | | NULL |Connect | 54 | Waiting for master tosend event | NULL | | 4| system user | | NULL |Connect | 53 | Slave has read all relaylog; waiting for the slave I/O thread to update it | NULL | +----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+ 3 rows in set (0.00 sec)
9.在master服務器建立數據庫，而後在從服務器上驗證是否存在
mysql> create database bds; Query OK, 1 row affected (0.00 sec) [root@node4 ~]# mysql -e 'show databases'; +--------------------+ | Database | +--------------------+ | information_schema | | bds | | mysql | | performance_schema | | test | +--------------------+ [root@node4 ~]# mysql -e 'show databases'; +--------------------+ | Database | +--------------------+ | information_schema | | bds | | mysql | | performance_schema | | test | +--------------------+
10．查看倆臺服務器的二進制日誌事件位置和是否一致
[root@node3 ~]# mysql -e 'show masterstatus'; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB |Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000003 | 436 | | | +------------------+----------+--------------+------------------+ [root@node4 ~]# mysql -e 'show slave status\G' | grep "Read" Read_Master_Log_Pos: 436
半同步複製
半同步複製表示master服務器只須要接收到其中一臺的slave服務器的返回信息，就會commit，不然須要等待直到超過
設定的時間，而後降級切換成異步再提交，這樣作的目的可使主從數據的數據延遲縮小，能夠在損失很小的性能前提下提升
數據的安全性。
1. 半同步的開啓比較簡單，只須要在master和slave服務器上都安裝上本同步插件並啓動便可。
2. 插件在mysql的安裝目錄中 ： /usr/local/mysql/lib/plugin/ (二進制形式安裝mysql的位置)
[root@node3 ~]# ll/usr/local/mysql/lib/plugin/ | grep "semi" -rwxr-xr-x. 1 root mysql 170178 Jul 15 2013 semisync_master.so -rwxr-xr-x. 1 root mysql 88895 Jul 15 2013 semisync_slave.so
3.在倆臺服務器上分別安裝插件
mysql> install pluginrpl_semi_sync_master soname 'semisync_master.so'; mysql> set globalrpl_semi_sync_master_enabled = 1 ; mysql> set globalrpl_semi_sync_master_timeout = 1000 ; mysql> install plugin rpl_semi_sync_slave soname 'semisync_slave.so'; mysql> set globalrpl_semi_sync_slave_enabled = 1; mysql> stop slave io_thread;start slaveio_thread;
3．查看半同步狀態
mysql> show global status like'rpl_semi%'; +--------------------------------------------+-------+ | Variable_name | Value | +--------------------------------------------+-------+ | Rpl_semi_sync_master_clients | 1 | |Rpl_semi_sync_master_net_avg_wait_time | 0 | | Rpl_semi_sync_master_net_wait_time | 0 | | Rpl_semi_sync_master_net_waits | 0 | | Rpl_semi_sync_master_no_times | 0 | | Rpl_semi_sync_master_no_tx | 0 | | Rpl_semi_sync_master_status | ON | |Rpl_semi_sync_master_timefunc_failures | 0 | |Rpl_semi_sync_master_tx_avg_wait_time | 0 | | Rpl_semi_sync_master_tx_wait_time | 0 | | Rpl_semi_sync_master_tx_waits | 0 | |Rpl_semi_sync_master_wait_pos_backtraverse | 0 | | Rpl_semi_sync_master_wait_sessions | 0 | | Rpl_semi_sync_master_yes_tx | 0 | +--------------------------------------------+-------+ mysql> show global variables like'%rpl%'; +------------------------------------+-------+ | Variable_name | Value | +------------------------------------+-------+ | rpl_recovery_rank | 0 | | rpl_semi_sync_master_enabled | ON | | rpl_semi_sync_master_timeout | 1000 | | rpl_semi_sync_master_trace_level | 32 | | rpl_semi_sync_master_wait_no_slave |ON | +------------------------------------+-------+ mysql> show global status like'rpl_semi%'; +----------------------------+-------+ | Variable_name | Value | +----------------------------+-------+ | Rpl_semi_sync_slave_status | ON | +----------------------------+-------+ mysql> show global variables like'%rpl%'; +---------------------------------+-------+ | Variable_name | Value | +---------------------------------+-------+ | rpl_recovery_rank | 0 | | rpl_semi_sync_slave_enabled | ON | | rpl_semi_sync_slave_trace_level | 32 | +---------------------------------+-------+
查看slave線程是否啓動
[root@node4 ~]# mysql -e 'show slavestatus\G' | grep "Running" Slave_IO_Running: Yes Slave_SQL_Running: Yes
5．在master服務器上將前面建立的’bds’數據庫刪除，而後驗證slave服務器同步狀態。
mysql> drop database bds; mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | test | +--------------------+ mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | test | +--------------------+
6．以上配置不會永久生效，若是想永久生效，須要寫在配置文件中重啓服務便可。
基於ssl的加密複製
由於mysql在傳輸數據的時候是明文傳輸的 ，再生產環境中很是的不安全 ，尤爲是在跨網絡環境中，
爲了解決這個問題，須要進行加密傳輸，因此用基於ssl的加密傳輸數據。
1. 將master服務器本身作成CA服務器
[root@node3 CA]# cd /etc/pki/CA/ [root@node3 CA]# (umask 077; openssl genrsa-out private/cakey.pem 2048 ) root@node3 CA]# openssl req -new -x509 -keyprivate/cakey.pem -out cacert.pem -days 365 You are about to be asked to enterinformation that will be incorporated into your certificate request. What you are about to enter is what iscalled a Distinguished Name or a DN. There are quite a few fields but you canleave some blank For some fields there will be a defaultvalue, If you enter '.', the field will be leftblank. ----- Country Name (2 letter code) [XX]:cn State or Province Name (full name) []:bj Locality Name (eg, city) [DefaultCity]:beijing Organization Name (eg, company) [DefaultCompany Ltd]:bds Organizational Unit Name (eg, section)[]:tech Common Name (eg, your name or your server'shostname) []:node3 Email Address []:node3@qq.com [root@node3 CA]# touch index.txt [root@node3 CA]# echo 01 > serial
2．爲master 建立證書申請並由CA服務器簽發證書
[root@node3 CA]# mkdir /usr/local/mysql/ssl/ -pv [root@node3 CA]# cd /usr/local/mysql/ssl/ [root@node3 ssl]# (umask 077; opensslgenrsa -out master.key 2048) [root@node3 ssl]# openssl req -new -keymaster.key -out master.csr -days 365 You are about to be asked to enterinformation that will be incorporated into your certificate request. What you are about to enter is what iscalled a Distinguished Name or a DN. There are quite a few fields but you canleave some blank For some fields there will be a defaultvalue, If you enter '.', the field will be leftblank. ----- Country Name (2 letter code) [XX]:cn State or Province Name (full name) []:bj Locality Name (eg, city) [DefaultCity]:beijing Organization Name (eg, company) [DefaultCompany Ltd]:bds Organizational Unit Name (eg, section)[]:tech Common Name (eg, your name or your server'shostname) []:node3 Email Address []:node3@qq.com Please enter the following 'extra'attributes to be sent with your certificate request A challenge password []: An optional company name []: [root@node3 ssl]# openssl ca -in master.csr-out master.crt -days 365 Using configuration from/etc/pki/tls/openssl.cnf Check that the request matches thesignature Signature ok Certificate Details: Serial Number: 1 (0x1) Validity Not Before: Dec 3 04:40:39 2014GMT Not After : Dec 3 04:40:39 2015GMT Subject: countryName = cn stateOrProvinceName = bj organizationName = bds organizationalUnitName = tech commonName = node3 emailAddress =node3@qq.com X509v3 extensions: X509v3 Basic Constraints: CA:FALSE Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier: BF:D7:B2:93:F5:67:00:58:1B:3B:B1:2D:93:E1:9F:2B:4B:15:52:0E X509v3 Authority Key Identifier: keyid:70:41:30:49:6D:7E:3F:9A:73:B2:25:15:B8:D1:6F:24:3F:3C:54:39 Certificate is to be certified untilDec 3 04:40:39 2015 GMT (365 days) Sign the certificate? [y/n]:y 1 out of 1 certificate requests certified, commit?[y/n]y Write out database with 1 new entries Data Base Updated
3.爲slave服務器建立證書申請
mkdir /usr/local/mysql/ssl [root@node4 ~]# cd /usr/local/mysql/ssl/ [root@node4 ssl]# (umask 077;openssl genrsa -out slave.key2048) [root@node4 ssl]# openssl req -new -keyslave.key -out slave.csr -days 365 You are about to be asked to enterinformation that will be incorporated into your certificate request. What you are about to enter is what iscalled a Distinguished Name or a DN. There are quite a few fields but you canleave some blank For some fields there will be a defaultvalue, If you enter '.', the field will be leftblank. ----- Country Name (2 letter code) [XX]:cn State or Province Name (full name) []:bj Locality Name (eg, city) [DefaultCity]:beijing Organization Name (eg, company) [DefaultCompany Ltd]:bds Organizational Unit Name (eg, section)[]:tech Common Name (eg, your name or your server'shostname) []:node4 Email Address []:node3@qq.com Please enter the following 'extra'attributes to be sent with your certificate request A challenge password []: An optional company name []:
爲服務器簽署證書
[root@node4 ssl]# scp slave.csrnode3:/root/ [root@node3 ~]# openssl ca -in/root/slave.csr -out /root/slave.crt -days 365 Using configuration from /etc/pki/tls/openssl.cnf Check that the request matches thesignature Signature ok Certificate Details: Serial Number: 2 (0x2) Validity Not Before: Dec 3 05:35:16 2014GMT Not After : Dec 3 05:35:16 2015GMT Subject: countryName = cn stateOrProvinceName = bj organizationName = bds organizationalUnitName = tech commonName = node4 emailAddress =node3@qq.com X509v3 extensions: X509v3 Basic Constraints: CA:FALSE Netscape Comment: OpenSSL Generated Certificate X509v3 Subject Key Identifier: BF:8A:0A:65:FC:92:75:64:CB:44:0D:DC:ED:FE:E5:E9:3E:85:5F:92 X509v3 Authority Key Identifier: keyid:70:41:30:49:6D:7E:3F:9A:73:B2:25:15:B8:D1:6F:24:3F:3C:54:39 Certificate is to be certified untilDec 3 05:35:16 2015 GMT (365 days) Sign the certificate? [y/n]:y 1 out of 1 certificate requests certified,commit? [y/n]y Write out database with 1 new entries Data Base Updated [root@node3 ~]# scp slave.crt node4:/usr/local/mysql/ssl/ [root@node3 ~]# scp /etc/pki/CA/cacert.pem node4:/usr/local/mysql/ssl/ [root@node3 ~]# cp/etc/pki/CA/cacert.pem /usr/local/mysql/ssl/
修改master與slave服務器證書屬主屬組爲mysql用戶
[root@node3 ~]# chown -R mysql.mysql/usr/local/mysql/ssl/ [root@node4 ssl]# chown -R mysql.mysql /usr/local/mysql/ssl/
修改配置文件開啓ssl加密功能
[root@node3 ~]# vi /etc/my.cnf ssl ssl_ca = /usr/local/mysql/ssl/cacert.pem ssl_cert = /usr/local/mysql/ssl/master.crt ssl_key = /usr/local/mysql/ssl/master.key [root@node4 ssl]# vi /etc/my.cnf [root@node3 ~]# service mysqld restart ssl ssl_ca = /usr/local/mysql/ssl/cacert.pem ssl_cert = /usr/local/mysql/ssl/slave.crt ssl_key = /usr/local/mysql/ssl/slave.key [root@node4 ssl]# service mysqld restart
在master服務器查看ssl加密是否開啓，而後建立受權一個基於密鑰認證的用戶
[root@node3 ~]# mysql mysql> show variables like "%ssl%" ; +---------------+---------------------------------+ | Variable_name | Value | +---------------+---------------------------------+ | have_openssl | YES | | have_ssl | YES | | ssl_ca | /usr/local/mysql/ssl/cacert.pem | | ssl_capath | | | ssl_cert | /usr/local/mysql/ssl/master.crt | | ssl_cipher | | | ssl_key | /usr/local/mysql/ssl/master.key | +---------------+---------------------------------+ mysql> grant replicationclient,replication slave on *.* to 'bds'@'192.168.%.%' identified by'budognshu' require ssl; mysql> flush privileges;
8 . 查看master服務器二進制日誌文件位置和事件位置用於slave服務器鏈接今後位置開始複製
mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB |Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000004 | 367 | | | +------------------+----------+--------------+------------------+
9. 測試使用加密用戶指定密鑰鏈接master服務器
[root@node4 ~]# mysql -ubds -pbudongshu -h192.168.17.15 --ssl-ca=/usr/local/mysql/ssl/cacert.pem --ssl-cert=/usr/local/mysql/ssl/slave.crt--ssl-key=/usr/local/mysql/ssl/slave.key Welcome to the MySQL monitor.

Type '\c' toclear the current input statement. mysql>
10. 查看slave服務器是否開啓ssl 加密 並鏈接master服務器
[root@node4 ~]# mysql mysql> show variables like"%ssl%"; +---------------+---------------------------------+ | Variable_name | Value | +---------------+---------------------------------+ | have_openssl | YES | | have_ssl | YES | | ssl_ca | /usr/local/mysql/ssl/cacert.pem | | ssl_capath | | | ssl_cert | /usr/local/mysql/ssl/slave.crt | | ssl_cipher | | | ssl_key | /usr/local/mysql/ssl/slave.key | +---------------+---------------------------------+ mysql> change master tomaster_host='192.168.17.15',master_user='bds',master_password='budongshu', -> master_log_file='mysql-bin.000004', -> master_log_pos=367, -> master_ssl=1, -> master_ssl_ca='/usr/local/mysql/ssl/cacert.pem', -> master_ssl_cert='/usr/local/mysql/ssl/slave.crt', -> master_ssl_key='/usr/local/mysql/ssl/slave.key';
11 .查看slave服務器狀態
mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status\G *************************** 1. row*************************** Slave_IO_State: Waiting formaster to send event Master_Host: 192.168.17.15 Master_User: bds Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000004 Read_Master_Log_Pos: 367 Relay_Log_File: relay_log.000002 Relay_Log_Pos: 253 Relay_Master_Log_File: mysql-bin.000004 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 367 Relay_Log_Space: 403 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: Yes Master_SSL_CA_File: /usr/local/mysql/ssl/cacert.pem Master_SSL_CA_Path: Master_SSL_Cert:/usr/local/mysql/ssl/slave.crt Master_SSL_Cipher: Master_SSL_Key:/usr/local/mysql/ssl/slave.key Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1
12 .驗證基於ssl複製
