Mysql Innodb Cluster測試
本文介紹mysql 8版本下的Innodb Cluster配置與測試過程，其核心仍是mysql的組複製功能，經過使用mysql shell簡化了組複製的配置過程，同時使用mysql route中間件實現了故障的自動轉移以及讀寫分離等功能。以前測試mysql組複製的時候有提出過中間件的問題，mysql-route是個不錯的解決方案，前文傳送門：http://www.javashuo.com/article/p-ukcijhex-ny.htmlmysql
1、環境介紹
操做系統：centos linux 7.2 64bit
mysql社區版: 8.0.11
mysql shell版本：8.0.11
mysql route版本：8.0.11linux
2、下載軟件包
一、mysql
https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.11-linux-glibc2.12-x86_64.tar.gzsql二、mysql-router
https://cdn.mysql.com//Downloads/MySQL-Router/mysql-router-8.0.11-linux-glibc2.12-x86-64bit.tar.gzshell三、mysql-shell
https://cdn.mysql.com//Downloads/MySQL-Shell/mysql-shell-8.0.11-linux-glibc2.12-x86-64bit.tar.gzbootstrap
3、安裝軟件包
（其餘兩臺主機同步配置）centos
一、配置hosts文件 # cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.115.5 vm1 192.168.115.6 vm2 192.168.115.7 vm3 二、安裝mysql-shell # tar -zxvpf mysql-shell-8.0.11-linux-glibc2.12-x86-64bit.tar.gz -C /usr/local/ # cd /usr/local/ # ln -s mysql-shell-8.0.11-linux-glibc2.12-x86-64bit/ mysql-shell 三、安裝mysql-route # tar -zxvpf mysql-router-8.0.11-linux-glibc2.12-x86-64bit.tar.gz -C /usr/local/ # cd /usr/local/ # ln -s mysql-router-8.0.11-linux-glibc2.12-x86-64bit/ mysql-router 四、安裝和初始化mysql # tar -zxvpf mysql-8.0.11-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ # cd /usr/local/ # ln -s mysql-8.0.11-linux-glibc2.12-x86_64/ mysql # groupadd -g 27 mysql # useradd -g mysql -u 27 -d /dev/null -s /sbin/nologin mysql # mkdir -p /mydata # chown -R mysql.mysql /mydata/ # cat /usr/local/mysql/my.cnf [client] password = 123456 [mysqld] innodb_buffer_pool_size = 256M socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 100M max_allowed_packet = 1M table_open_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M read_rnd_buffer_size = 4M myisam_sort_buffer_size = 16M thread_cache_size = 4 max_connections=1500 character_set_server=utf8 group_concat_max_len=65535 log_bin_trust_function_creators=1 log_queries_not_using_indexes = ON log_throttle_queries_not_using_indexes = 2 log-bin=mysql-bin binlog_format=row default_authentication_plugin = mysql_native_password long_query_time=2 slow_query_log=1 slow_query_log_file=/mydata/slow-query.log ft_min_word_len=1 innodb_ft_min_token_size=1 server-id=1155 lower_case_table_names = 1 skip-name-resolve innodb_file_per_table=1 gtid_mode = ON enforce_gtid_consistency = ON slave_parallel_workers=4 master_verify_checksum = 1 slave_sql_verify_checksum = 1 log-slave-updates=true sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES slave-parallel-type=LOGICAL_CLOCK slave-preserve-commit-order=ON master_info_repository = TABLE relay_log_info_repository = TABLE # /usr/local/mysql/bin/mysqld --defaults-file=/usr/local/mysql/my.cnf --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/mydata --initialize-insecure # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld # egrep 'basedir|datadir' /etc/init.d/mysqld |head -n 5 # basedir=<path-to-mysql-installation-directory> # - Add the path to the mysql-installation-directory to the basedir variable # If you change base dir, you must also change datadir. These may get basedir=/usr/local/mysql datadir=/mydata # chmod +x /etc/init.d/mysqld # chkconfig --add mysqld # mv /etc/my.cnf /etc/my.cnf.bak # ln -s /usr/local/mysql/my.cnf /etc/ # service mysqld start mysql> set sql_log_bin=0; mysql> update mysql.user set host='%' where user='root'; mysql> alter user 'root'@'localhost' identified with mysql_native_password by '123456'; mysql> create user test@'%' identified by '123456'; mysql> grant all privileges on *.* to test@'%'; mysql> flush privileges; mysql> set sql_log_bin=1;
4、檢查配置
vm1執行便可服務器
使用JS命令，檢查每臺服務器的配置。三臺服務的mysql都要執行檢查
# /usr/local/mysql-shell/bin/mysqlsh
MySQL JS > dba.checkInstanceConfiguration('test@vm1:3306')
Please provide the password for 'test@vm1:3306': ******
Validating local MySQL instance listening at port 3306 for use in an InnoDB cluster...
This instance reports its own address as vm1
Clients and other cluster members will communicate with it through this address by default. If this is not correct, the report_host MySQL system variable should be changed.
Checking whether existing tables comply with Group Replication requirements...
No incompatible tables detected
Checking instance configuration...
Instance configuration is compatible with InnoDB cluster
The instance 'vm1:3306' is valid for InnoDB cluster usage.
{
"status": "ok"
}
執行 dba.checkInstanceConfiguration，當輸出 "status": "ok"的時候，表示該服務器檢查經過
5、建立組複製
vm1執行便可session
# /usr/local/mysql-shell/bin/mysqlsh --uri test@vm1:3306
MySQL vm1:3306 ssl JS > var cluster = dba.createCluster('main')
A new InnoDB cluster will be created on instance 'root@vm1:3306'.
Validating instance at vm1:3306...
This instance reports its own address as vm1
Instance configuration is suitable.
Creating InnoDB cluster 'main' on 'root@vm1:3306'...
Adding Seed Instance...
Cluster successfully created. Use Cluster.addInstance() to add MySQL instances.
At least 3 instances are needed for the cluster to be able to withstand up to
one server failure.
JS > cluster.addInstance('root@vm2:3306')
JS > cluster.addInstance('root@vm3:3306')
MySQL vm1:3306 ssl JS > cluster.status()
{
"clusterName": "main",
"defaultReplicaSet": {
"name": "default",
"primary": "vm1:3306",
"ssl": "REQUIRED",
"status": "OK",
"statusText": "Cluster is ONLINE and can tolerate up to ONE failure.",
"topology": {
"vm1:3306": {
"address": "vm1:3306",
"mode": "R/W",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
},
"vm2:3306": {
"address": "vm2:3306",
"mode": "R/O",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
},
"vm3:3306": {
"address": "vm3:3306",
"mode": "R/O",
"readReplicas": {},
"role": "HA",
"status": "ONLINE"
}
}
},
"groupInformationSourceMember": "mysql://root@vm1:3306"
}
6、配置mysql-route
vm1執行便可app
# useradd mysql-router # /usr/local/mysql-router/bin/mysqlrouter --bootstrap root@vm3:3306 --user mysql-router --directory /data/mysqlrouter --user=root --conf-use-sockets --force Please enter MySQL password for root: Reconfiguring MySQL Router instance at '/data/mysqlrouter'... MySQL Router has now been configured for the InnoDB cluster 'main'. The following connection information can be used to connect to the cluster. Classic MySQL protocol connections to cluster 'main': - Read/Write Connections: localhost:6446 - Read/Write Connections: /data/mysqlrouter/mysql.sock - Read/Only Connections: localhost:6447 - Read/Only Connections: /data/mysqlrouter/mysqlro.sock X protocol connections to cluster 'main': - Read/Write Connections: localhost:64460 - Read/Write Connections: /data/mysqlrouter/mysqlx.sock - Read/Only Connections: localhost:64470 - Read/Only Connections: /data/mysqlrouter/mysqlxro.sock # /data/mysqlrouter/start.sh # netstat -anpt |grep router tcp 0 0 0.0.0.0:64460 0.0.0.0:* LISTEN 4865/mysqlrouter tcp 0 0 0.0.0.0:6446 0.0.0.0:* LISTEN 4865/mysqlrouter tcp 0 0 0.0.0.0:6447 0.0.0.0:* LISTEN 4865/mysqlrouter tcp 0 0 0.0.0.0:64470 0.0.0.0:* LISTEN 4865/mysqlrouter tcp 0 0 192.168.115.5:6446 192.168.115.1:63131 ESTABLISHED 4865/mysqlrouter tcp 0 0 192.168.115.5:36458 192.168.115.5:3306 ESTABLISHED 4865/mysqlrouter tcp 0 0 192.168.115.5:46488 192.168.115.7:3306 ESTABLISHED 4865/mysqlrouter
