|
本篇内容主要讲解“怎么实现mysql 5.7主主同步”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“怎么实现mysql 5.7主主同步”吧! 一.环境: OS:CentOS 6.5 X64 DB Version:Percona Mysql 5.7.15-9-log 路径:/app/mysql57 数据文件路径:/data/mysql57/data DB1:192.168.213.4 DB2:192.168.213.5 二.安装Mysql 1.安装依赖包 yum -y install gcc gcc-c++ ncurses ncurses-devel cmake readline-devel 2.创建所需目录 mkdir -pv /app/mysql57 mkdir -pv /data/mysql56/data/ 3.创建用户及赋权 useradd -M -s /sbin/nologin mysql chown -R mysql:mysql /app/mysql57 chown -R mysql:mysql /data/mysql57 4.下载所需目录 cd /usr/local/tools wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz tar xzf boost_1_59_0.tar.gz wget https://www.percona.com/downloads/Percona-Server-5.7/Percona-Server-5.7.15-9/source/tarball/percona-server-5.7.15-9.tar.gz tar xf percona-server-5.7.15-9.tar.gz cd percona-server-5.7.15-9 cmake .

max_allowed_packet = 32M user=root password=system 6.初始化数据库 /app/mysql57/bin/mysqld --initialize-insecure --user=mysql --basedir=/app/mysql57 --datadir=/data/mysql57/data 备注:--initialize-insecure不会生成随机密码,安装后建议运行安全脚本 7.修改环境变量 echo "export PATH=$PATH:/app/mysql57/bin " >/etc/profile.d/mysql57.sh source /etc/profile.d/mysql57.sh /etc/init.d/mysqld57 start 三.配置复制 1.db01配置 CREATE USER 'repl'@'%' IDENTIFIED BY '12345678'; GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%'; 2.db02配置 CREATE USER 'repl'@'%' IDENTIFIED BY '12345678'; GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%'; 3.两台主机锁库 FLUSH TABLES WITH READ LOCK; db01主机查看master pos root@localhost 23:21: [(none)]> show master status \G *************************** 1. row *************************** File: bin_log.000009
