准备工作：
主从机上作操作----关闭selinux和iptables或者开放3306端口（iptables -A INPUT -p tcp --dport 3306 -j ACCEPT iptables -A OUTPUT -p tcp --sport 3306 -j ACCEPT）,时间同步ntpdate time.windows.com
mysql_1信息：主
[[email protected]_1 ~ 10:30 &6]#cat /etc/redhat-release ;uname -r ;ifconfig eth0 |grep ‘inet addr‘ |awk -F ‘:‘ ‘{print $2}‘ |echo ip:`awk -F ‘ ‘ ‘{print $1}‘`
CentOS release 6.5 (Final)
2.6.32-431.el6.i686
ip:172.31.12.4
mysql_2信息：从
[[email protected]_2 ~ 11:02 &18]#cat /etc/redhat-release ;uname -r ;ifconfig eth1 |grep ‘inet addr‘ |awk -F ‘:‘ ‘{print $2}‘ |echo ip:`awk -F ‘ ‘ ‘{print $1}‘`
CentOS release 6.5 (Final)
2.6.32-431.el6.i686
ip:172.31.12.233
下载mysql并解压:这里只演示从机
cd /usr/local/src/
[[email protected]_2 ~ 11:19 &20]#wget http://syslab.comsenz.com/downloads/linux/mysql-5.1.40-linux-i686-icc-glibc23.tar.gz [[email protected]_2 src 11:24 &23]#tar -zxvf mysql-5.1.40-linux-i686-icc-glibc23.tar.gz
移动解压目录到/usr/loca/下：创建mysql目录
[[email protected]_2 src 11:26 &26]#mv mysql-5.1.40-linux-i686-icc-glibc23 /usr/local/mysql
创建mysql用户：禁止mysql用户登录bash登录
[[email protected]_2 src 13:13 &27]#useradd -s /sbin/nologin mysql
创建mysql安装目录，并修改为mysql属主属组：
[[email protected]_2 src 13:14 &28]#mkdir -p /data/mysql [[email protected]_2 src 13:16 &29]#chown -R mysql:mysql /data/mysql/
进入到/usr/local/mysql目录下初始化mysql:
[[email protected]_2 src 13:16 &30]#cd /usr/local/mysql/ [[email protected]_2 mysql 13:19 &31]#./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
拷贝mysql主配置文件到/etc/目录下并重命名为my.cnf:
[[email protected]_2 mysql 13:21 &32]#cp support-files/my-large.cnf /etc/my.cnf
拷贝mysql的启动脚本到/etc/init.d/目录下并重命名为mysqld并讲权限修改为755：
[[email protected]_2 mysql 13:27 &33]#cp support-files/mysql.server /etc/init.d/mysqld [[email protected]_2 mysql 13:29 &35]#chmod 755 /etc/init.d/mysqld
编辑启动脚本：
[[email protected]_2 mysql 13:30 &36]#vim /etc/init.d/mysqld 指定mysql的安装目录：datadir=/data/mysql
把启动脚本加入到服务项中，并设置为开机启动：
[[email protected]_2 mysql 13:33 &37]#chkconfig --add mysqld [[email protected]_2 mysql 13:35 &38]#chkconfig mysqld on
修改从配置文件服务id号为2：
[[email protected]_2 mysql 13:38 &40]#vim /etc/my.cnf server-id = 1 改为 server-id = 2
设置mysql 命令路径：vim /etc/profile,在末尾加上并刷新服务：
[[email protected]_2 mysql 13:39 &41]#echo PATH=$PATH:/usr/local/mysql/bin >> /etc/profile [[email protected]_2 mysql 13:41 &43]#source /etc/profile
启动mysql服务：
[[email protected]_2 mysql 13:42 &45]#service mysqld start
以上步骤，分别在两台服务器上配置好！
分别给主从mysql设置密码：
[[email protected]_2 mysql 13:44 &46]#mysqladmin -uroot password ‘123456‘
登陆mysql主、从服务器，分别建立数据库 db1：
[[email protected]_2 mysql 13:47 &47]#mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
