Mysql-Oneproxy讀寫分離+分庫分表

Oneproxy讀寫分離

1、Oneproxy讀寫分離

主服務器（Master）：192.168.32.150
從服務器（slave）：192.168.32.129
oneproxy中間件服務器：192.168.32.150

---

一、首先要配置好主從複製而且在主服務器上建立test庫

mysql>create database test;

mysql> show databases;

添加oneproxy的鏈接用戶會自動replication到slave數據庫

mysql>grant select,delete,insert,update,create on test.* to oneproxy@'%' identified by '123456';

---

二、關閉三臺服務器的防火牆或者配置防火牆策略

Mysql：3306

oneproxy鏈接端口3307

oneproxy管理端口4041

[root@localhost ~]# systemctl stop firewalld.service

①開啓oneproxy自動識別讀寫服務器（從服務器配置）

[root@localhost ~]# vim /etc/my.cnf

添加：read_only = 1

②重啓mysql服務

[root@localhost ~]# systemctl restart mysqld

mysql> show variables like "%read_only%";

或者 mysql>set global read_only = 1; //臨時開啓

---

三、配置oneproxy中間件（oneproxy服務器）

①安裝oneproxy

[root@localhost ~]# wget http://www.onexsoft.com/software/oneproxy-rhel6-linux64-v6.2.0-ga.tar.gz

[root@localhost ~]# tar zxf oneproxy-rhel6-linux64-v6.2.0-ga.tar.gz -C /usr/local/

②在預啓動腳本中修改oneproxy目錄

[root@localhost ~]# vim /usr/local/oneproxy/demo.sh

~

#/bin/bash

export ONEPROXY_HOME=/usr/local/oneproxy

ulimit -c unlimited

valgrind --leak-check=full \

${ONEPROXY_HOME}/bin/oneproxy --defaults-file=${ONEPROXY_HOME}/conf/proxy.conf

③修改啓動腳本oneproxy目錄

[root@localhost ~]#vim /usr/local/oneproxy/oneproxy.service

............................

OneProxy Settings

ONEPROXY_HOME=/usr/local/oneproxy

ONEPROXY_SBIN="${ONEPROXY_HOME}/bin/oneproxy"

ONEPROXY_CONF="${ONEPROXY_HOME}/conf/proxy.conf"

ONEPROXY_PID="${ONEPROXY_HOME}/log/oneproxy.pid"

RETVAL=0

prog="OneProxy"

④獲取oneproxy加密後的密文密碼

[root@localhost ~]# cd /usr/local/oneproxy/bin/

[root@localhost bin]# ls

[root@localhost bin]# ./mysqlpwd 123456

9D7E55EAF8912CCBF32069443FAC452794F8941B

⑤修改oneproxy主配文件

[root@localhost ~]# mysql --version

[root@localhost bin]# vim /usr/local/oneproxy/conf/proxy.conf

[oneproxy]

#proxy-license = A2FF461456A67F28,D2F6A5AD70C9042D

keepalive = 1

event-threads = 4

proxy-group-policy = test:read-slave

log-file = log/oneproxy.log

pid-file = log/oneproxy.pid

lck-file = log/oneproxy.lck

proxy-auto-readonly = 1

proxy-forward-clientip = 1

proxy-trans-debug = 1

mysql-version = 5.7.21

proxy-master-addresses.1 = 192.168.32.150:3306@test

proxy-slave-addresses.2 = 192.168.32.129:3306@test

proxy-user-list = oneproxy/9D7E55EAF8912CCBF32069443FAC452794F8941B@test

proxy-part-template = conf/template.txt

proxy-part-tables.1 = conf/part.txt

proxy-part-tables.2 = conf/part2.txt

proxy-part-tables.3 = conf/cust1.txt

proxy-charset = utf8_bin

proxy-secure-client = 127.0.0.1

proxy-httpserver = :8080

proxy-httptitle = OneProxy Monitor

proxy-auto-readonly：自動切換讀寫角色
proxy-group-policy： 預約義策略，對應真實要管理的數據庫
proxy-user-list： 指明鏈接數據庫用戶密文密碼要與真實數據庫用戶密碼對應@符後指的是數據庫

啓動oneproxy並查看端口

[root@localhost bin]# cd ..

[root@localhost oneproxy]# chmod +x demo.sh

[root@localhost oneproxy]# ./demo.sh

[root@localhost oneproxy]# ./oneproxy.service start

[root@localhost oneproxy]# ss -anpt | grep 3307

[root@localhost oneproxy]# ss -anpt | grep 4041

---

五、驗證

因爲oneproxy爲了安全起見，初始靜止了DDl語句，須要去到4041管理端口打開底層數據庫權限（從服務器）

[root@localhost ~]# mysql -uadmin -pOneProxy -P4041 -h 192.168.32.149

mysql> set gaccess test 0 ;

使用客戶端登陸oneproxy鏈接端口3307（主服務器）

[root@localhost ~]# mysql -uoneproxy -p123456 -h 192.168.32.149 -P3307

mysql> create table test.tb (id int);

mysql> insert into test.tb values(1);

mysql> select * from test.tb;

觀察管理網頁master和slave中query的變化,讀負載的增長與寫負載的增長，驗證成功

訪問oneproxy管理網頁
格式：輸入http://192.168.32.149:8080
默認用戶名admin，密碼OneProxy

---

OneProxy簡單實現Mysql分庫分表

①修改配置文件proxy.conf

[root@localhost ~]#vim /usr/local/oneproxy/conf/proxy.conf

[oneproxy]

#proxy-license = A2FF461456A67F28,D2F6A5AD70C9042D

keepalive = 1

event-threads = 4

proxy-group-policy.1 = test:master-only

proxy-group-security = test:0log-file = log/oneproxy.log

pid-file = log/oneproxy.pid

lck-file = log/oneproxy.lck

proxy-forward-clientip = 1

proxy-trans-debug = 1

mysql-version = 5.7.21

proxy-master-addresses.1 = 192.168.32.187:3306@test

proxy-user-list = oneproxy/9D7E55EAF8912CCBF32069443FAC452794F8941B@test

proxy-part-template = conf/template.txt

proxy-part-tables.1 = conf/part.txt

proxy-part-tables.2 = conf/part2.txt

proxy-part-tables.3 = conf/cust1.txt

proxy-charset = utf8_bin

proxy-httpserver = :8080

proxy-httptitle = OneProxy Monitor

---

②修改配置文件part2.txt

[root@localhost oneproxy]#cd /usr/local/oneproxy/conf

[root@localhost conf]#vim part2.txt

[

{

"table" : "user",

"pkey" : "id",

"type" : "int",

"method" : "hash",

"partitions" :

[

{ "suffix" : "_0", "group": "test" },

{ "suffix" : "_1", "group": "test" },

{ "suffix" : "_2", "group": "test" },

{ "suffix" : "_3", "group": "test"}

]

}

]

---

③啓動oneproxy並查看端口

[root@localhost conf]# cd ..

[root@localhost oneproxy]# ./demo.sh

[root@localhost oneproxy]# ./oneproxy.service start

[root@localhost oneproxy]# ss -anpt | grep 3307

[root@localhost oneproxy]# ss -anpt | grep 4041

若是端口查詢不到，能夠查看oneproxy日誌文件oneproxy.log。

若是沒有日誌記錄，多是主配或part文件有錯誤

---

驗證
①從客戶端登陸鏈接端口（主服務器）

[root@localhost ~]# mysql -h 192.168.32.149 -uoneproxy -p123456 -P3307

mysql> show databases;

②插入數據

mysql>create table user(id int ,c1 int);
mysql>insert into user(id,c1) values (1,1);
mysql>insert into user(id,c1) values (2,2);
mysql>insert into user(id,c1) values (3,3);
mysql>insert into user(id,c1) values (4,4);
mysql>insert into user(id,c1) values (5,5);

③查看
mysql>select * from user;

④回到mysql查看存儲位置

[root@localhost ~]# mysql -uroot -p123456

mysql> use test;

mysql> show tables ;

mysql> select * from user_0;

mysql> select * from user_1;

mysql> select * from user_2;

mysql> select * from user_3;
