[root@node1 mysql-5.7.4]# vim /etc/my.cnf
basedir = /usr/local/mysql-5.7.4
datadir = /var/lib/mysql
port = 3306
[root@node1 mysql-5.7.4]# chown mysql:mysql /var/lib/mysql/
[root@node1 mysql-5.7.4]# cp -a support-files/mysql.server /etc/init.d/mysqld
[root@node1 mysql-5.7.4]# chkconfig --add mysqld

7.资源切换,测试mysqk服务是否正常
node1节点:
[root@node1 ~]# netstat -antup | grep 3306
tcp 0 0 :::3306 :::* LISTEN 28750/mysqld
[root@node1 ~]# /usr/share/heartbeat/hb_standby
Going standby [all].
[root@node1 ~]# netstat -antup | grep 3306
[root@node1 ~]#
node2节点:
[root@node2 ~]# netstat -antp | grep 3306
tcp 0 0 :::3306 :::* LISTEN 11091/mysqld
[root@node2 ~]# /usr/local/mysql-5.7.4/bin/mysql -u remote -p -h 192.168.1.100
