基于 Amoeba 实现 MySQL 读写分离
基于 Amoeba 实现 MySQL 读写分离
环境要求
Master Centos7.x 192.168.1.101 MySQL Slave1 Centos7.x 192.168.1.101 MySQL Slave2 Centos7.x 192.168.1.101 MySQL Slave1 Centos7.x 192.168.1.101 Amoeba-MySQL-binary jdk1.8 客户端 Centos7.x 192.168.1.101 MySQL—Client
一 、 部署 MySQL 主从复制
1 建立时间同步环境 在主节点部署时间同步服务器
1、安装 NTP [root@localhost ~]# yum install ntp ntpdate -y 2、 配置 NTP [root@localhost ~]# vi /etc/ntp.conf server 127.127.1.0 fudge 127.127.1.0 stratum 8 3 、重启 NTP 服务 [root@localhost ~]# systemctl restart ntpd
2 在从节点进行时间同步
[root@localhost ~]# yum install ntpdate -y [root@localhost ~]# /usr/sbin/ntpdate 192.168.1.101
其他节点相同操作
3 在每台服务器关闭 firewalld 或者 iptables 防火墙
[root@localhost ~]# systemctl stop firewalld [root@localhost ~]# systemctl disable firewalld centos7.x 以上版本操作 [root@localhost ~]# service iptables stop [root@localhost ~]# chkconfig iptables off centos6.x 包括 centos5.x版本操作防火墙方法
4 安装 MySQL 数据库 在 Master Slave1 Slave2 节点
安装 mysql 源
rpm -vih https://repo.mysql.com//mysql80-community-release-el7-3.noarch.rpm
安装 yum 扩展工具
yum install yum-utils -y
启用mysql80-community 源
启用mysql80-community 源 yum-config-manager --enable mysql57-community 禁用mysql80-community 源 默认是启用的 yum-config-manager --disable mysql80-community
在 Master Slave1 Slave2 执行安装 Mysql 服务
yum install mysql-community-server -y
在客户端安装
yum install mysql-community-client -y
配置主从 MySQL 同步
配置 Master 主服务器
修改/etc/my.cnf 配置文件 [root@localhost ~]# vi /etc/my.cnf server-id = 11 log-bin = master-bin log-slave-updatees = true 重启 Master 节点服务
配置 Slave 从服务器
修改/etc/my.cnf 配置文件 [root@localhost ~]# vi /etc/my.cnf server-id = 22 #多个从节点服务器 需要配置不同的 id relay-log-index=slave-relay-bin.index relay-log=slave-relay-bin 连接Master change master to master_host='192.168.0.104', //Master 服务器Ip master_port=3306, master_user='repl', master_password='mysql', master_log_file='master-bin.000001',//Master服务器产生的日志 master_log_pos=0;
