在Linux服务器lvs负载均衡、双机热备应用中经常用到MySQL双机热备,安装和配置过程如下:
一、 安装MySQL
# cp mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz /usr/local/
# tar zxvf mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz
# mv mysql-standard-4.1.9-pc-linux-gnu-i686 mysql
# cd mysql
# more INSTALL-BINARY
查看安装文档,注意以红色框内为主。
# groupadd mysql (建立mysql组)
# useradd -g mysql mysql (建立mysql用户并将其用户加入该组)
# scripts/mysql_install_db --user=mysql (以mysql用户身份执行数据库初始化安装脚本)
# chown -R root . (归属root权限为当前目录)
# chown -R mysql data (归属mysql权限为data目录)
# chgrp -R mysql . (改变mysql档案/目录的使用者与群组拥有人为当前目录)
# bin/mysqld_safe --user=mysql & (以mysql用户身份后台启动mysql数据库进程)
之后我们就可以启动mysql数据库,,如图:
显示为上述图,表示安装正确。
为了使数据库更加安全,我们来设置数据库密码。
如在下次启动服务器时能自动启动mysql数据库进程,我们还需写入/etc/rc.d/rc.local文件里
echo “/usr/local/mysql/bin/mysqld_safe --user=mysql &” >;>; /etc/rc.d/rc.local
