源代码编译MYSQL5.6环境下的MHA+KEEPALIVED的安装和维护

前言摘要MHA是当master出现故障，挑选一个slave作为新的master并构建成新的主从架构的管理工具。从master出..

[root@MYSQL ~]# cd /usr/local/src/ [root@MYSQL src]# ls installmysql5.sh mysql-5.6.10 mysql-5.6.10.tar.gz [root@MYSQL src]# sh installmysql5.sh please enter you mysql version (eg:/mysql-5.5.34):mysql-5.6.10 please enter you mysql datadir (eg:/data/mysql/data):/date/mysql/data

# 所有mysql数据库服务器，安装半同步插件(semisync_master.so,semisync_slave.so) mysql> install plugin rpl_semi_sync_master soname 'semisync_master.so'; mysql> install plugin rpl_semi_sync_slave soname 'semisync_slave.so'; [root@MYSQL etc]vi /etc/my.cnf [mysqld] rpl_semi_sync_master_enabled=1 rpl_semi_sync_master_timeout=1000 rpl_semi_sync_slave_enabled=1 relay_log_purge=0 skip-name-resolve #socket=/usr/mysql.sock #auto_increment_offset = 2 #auto_increment_increment = 2 server-id = 1 log-bin=mysql-bin read_only=1 slave-skip-errors=1396

rpl_semi_sync_master_net_avg_wait_time：事务进入等待队列后，到网络平均等待时间

[root@MYSQL src]# service mysqld restart 每台机器重启4.每一台机器配置互相无交互

[root@MYSQL src]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.186.141 MYSQL.COM 192.168.186.142 SLAVE1.COM 192.168.186.146 SLAVE2.COM 192.168.186.144 MANAGER.COM [root@MYSQL src]# ssh-keygen [root@MYSQL src]# ssh-copy-id 192.168.186.142 [root@MYSQL src]# ssh-copy-id 192.168.186.144 [root@MYSQL src]# ssh-copy-id 192.168.186.146 其他台配置方法与以上一致 保证每台互相无交互 配置完成后每一个都登录一次 [root@MYSQL ~]# ssh MANAGER.COM [root@MYSQL ~]# ssh SLAVE1.COM [root@MYSQL ~]# ssh SALVE2.COM 作用首次连接需要输入一次YES 在know-hosts问价记录，达成无交互5.配置主从

执行主从脚本

建议自己做 用这个脚本要是后期带来各种不便 不要怪我

详见附件

[root@MYSQL src]# sh mslave.sh please enter you mysql SLAVEIP (eg:192.168.152.138):192.168.186.142 please enter you master mysql password (eg:yunwei123):123 please enter you slave mysql password (eg:yunwei123):123 please enter you master mysql binlog (eg:mysql-bin.000001):mysql-bin.000001 [root@MYSQL src]# sh mslave.sh please enter you mysql SLAVEIP (eg:192.168.152.138):192.168.186.146 please enter you master mysql password (eg:yunwei123):123 这个是你的主MYSQL 登录密码 please enter you slave mysql password (eg:yunwei123):123 这个是你的从的MYSQL登录密码 please enter you master mysql binlog (eg:mysql-bin.000001):mysql-bin.000001 至此MYSQL 安装主从半同步配置完成

三．安装配置MHA

1.安装
