oneproxy基於一主一從的MySQL 讀寫分離配置步驟

環境準備：
a. 搭建好MySQL 主從複製環境
b. 下載並安裝好oneproxy，並能正常啟動

oneproxy讀寫分離配置
1.MySQL Master上建立三個使用者
a)metadb使用者，建立oneproxy schema的庫和表。
create database oneproxy;
GRANT SELECT, INSERT, UPDATE, DELETE,CREATE ON oneproxy.* TO ‘metadb’@’127.0.0.1’ IDENTIFIED BY ‘123456’;

b)repadmin 主從複製監控使用者
GRANT REPLICATION SLAVE, REPLICATION CLIENT ON .

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON test.* TO ‘repadmin’@’%’ ;

c)訪問mysql的業務使用者
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON test.* TO ‘test’@’%’ IDENTIFIED BY ‘123456’;

2.用oneproxy帶的mysqlpwd對密碼進行加密
/oneproxy/bin/mysqlpwd 123456
9D7E55EAF8912CCBF32069443FAC452794F8941B

/oneproxy/bin/mysqlpwd 123
956C97523BADD23B6091B09E332A77B5CBDBBEEF

3.在/oneproxy/conf/proxy.conf中新增如下配置
metadb-username = metadb
metadb-password = 9D7E55EAF8912CCBF32069443FAC452794F8941B
metadb-address = 172.25.18.94:3316

proxy-user-list = oneuser/[email protected]
proxy-user-group = server1:test/

repadmin-username = repadmin
repadmin-password = 9D7E55EAF8912CCBF32069443FAC452794F8941B

proxy-master-addresses = 172.25.18.94:[email protected]
proxy-slave-addresses = 172.25.1814:[email protected]
proxy-secure-client = 172.25.18.94
proxy-group-security = server1:4
proxy-group-policy = server1:read_slave
proxy-group-slavedelay = server1:2
proxy-replication-check = 1
proxy-force-master = t2

4.重啟oneproxy

5.驗證讀寫分離
可根據返回的server_id判斷請求轉發到master還是slave上。
也可以開啟general_log ,觀察sql執行情況。

正常情況begin;select @@server_id;commit; 轉發到mastr上；
select @@server_id ；轉發到slave上；

mysql -utest -p123 -h172.25.18 -P3307 -e “begin;select @@server_id;commit;”

mysql -utest -p123 -h172.25.18 -P3307 -e “select @@server_id;”
