一、安装前准备
关闭iptables:
service iptables stop;
chkconfig iptables off
关闭SELinux
vi /etc/selinux/config
查询系统是否有安装mysql,如有则移除。
rpm -qa | grep mysql
移除已安装的mysql:
yum remove mysql-libs-5.1.66-2.el6_3.x86_64
二、安装数据库
安装需要的插件:
yum install perl perl-devel libaiolibaio-devel
安装MySQL-shared-compat 替换mysql-libs,如果不替换,在删除mysql-libs,会提示postfix依赖于mysql-libs
rpm -ivh MySQL-shared-compat-5.6.26-1.el6.x86_64.rpm
安装服务端:
rpm -ivh MySQL-server-5.6.26-1.el6.x86_64.rpm
安装客户端:
rpm -ivh MySQL-client-5.6.26-1.el6.x86_64.rpm
设置开机自动启动:
chkconfig mysql on
启动mysql:
service mysql start
停止mysql:
service mysql stop
获取root的密码:
more /root/.mysql_secret
修改root密码并删除匿名账户:
/usr/bin/mysql_secure_installation--user=mysql
修改主机名:
vi /etc/sysconfig/network
vi /etc/hosts
修改主服务器配置文件(配置文件见附件):
vi /usr/my.cnf
修改从服务器配置文件(配置文件见附件):
进入mysql:
mysql -u root -p
show master status
show global variables like '%uuid%'
在两台机器上都创建复制账户并授权:
grant replication slave on *.* to 'mysql'@'192.168.2.%'identified by 'mysql';
flush privileges; #重加载权限
从库连接主库:
change master to master_host='192.168.2.61',master_user='mysql',master_password='mysql', master_port=3306,master_auto_position=1;
start slave;
主库连接从库:
change master to master_host='192.168.2.62',master_user='mysql',master_password='mysql', master_port=3306,master_auto_position=1;
start slave;
三、安装并配置keepalived(配置文件见附件)
yum install keepalived
vi /etc/keepalived/keepalived.conf
四、测试:
grant all privileges on *.* to 'root'@'%'identified by '123456';
mysql -h "192.168.2.60" -u root �Cp
show variables like "server_id";
show processlist;
show databases;
show slave status\G;
show master status\G;
