介绍shell脚本部署mysql主从

服务器配置信息如下：
centos6两台
Master IP：192.168.88.153
Slave IP：192.168.88.152

ssh-keygen -t rsa
ssh-copy-id root@192.168.88.153

#!/bin/bash
service iptables stop
setenforce 0
yum -y install mysql mysql-server
sed -ie '7a/server-id=1/nlog-bin=mysql-bin/nrelay-log/n' /etc/my.cnf
service mysqld restart
mysql -e " grant all on *.* to 'tom'@'%' identified by '123'; "
mysql -e " flush privileges; "
mysql -e " show master status; "

#!/bin/bash
bin=`ssh root@192.168.88.152 "mysql -e 'show master status;'|grep mysql"`
file=`echo $bin|awk -F ' ' '{print $1}'`
pos=`echo $bin|awk -F ' ' '{print $2}'`
service iptables stop
setenforce 0
yum -y install mysql mysql-server
sed -ie '7a/server-id=1/nlog-bin=mysql-bin/nrelay-log/n' /etc/my.cnf
service mysqld start
mysql -e "change master to master_host='192.168.88.152',master_user='tom',master_password='123',master_log_file='$file',master_log_pos=$pos;"
mysql -e 'start slave'
mysql -e 'show slave status /G;'

IO=`mysql -e "show slave status/G;" 2>/dev/null |grep Slave_IO_Running|awk -F ':' '{print $2}'`
SQL=`mysql -e "show slave status/G;" 2>/dev/null |grep Slave_SQL_Running|awk -F ':' '{print $2}'`
if [ $IO == "Yes" -a $SQL == "Yes" ]
then
echo "成功"
else
echo "失败"
fi

将mysql_slave.sh复制到slave主机

scp mysql_slave.sh 192.168.88.153:/root/

sh mysql_master.sh
ssh root@192.168.88.153 "sh /root/mysql_slave.sh"
