我主要体验了下几个关于REPLICATION的工具。其他的可以参见手册。先说下我的环境：MASTER:192.168.1.131SLAVE:192.168.1.132,192.168.1.133三台DB都有对外的ALL
我主要体验了下几个关于replication的工具。 其他的可以参见手册。
先说下我的环境：
MASTER: 192.168.1.131
SLAVE: 192.168.1.132, 192.168.1.133
三台DB都有对外的ALL权限用户。
各个配置文件如下，
[root@mysql56-master home]# cat /etc/my.cnf[mysqld]user = yttskip-name-resolveinnodb_buffer_pool_size = 128Mbasedir = /usr/local/mysqldatadir = /usr/local/mysql/dataport = 3306server_id = 131socket = /tmp/mysql.sockexplicit_defaults_for_timestamplog-bin=mysql56-master-binbinlog-ignore-db=mysqlgtid-mode=onenforce-gtid-consistencylog-slave-updatesbinlog-format=ROWsync-master-info=1report-host=192.168.1.131report-port=3306master_info_repository=tablerelay_log_info_repository=table
其他两台SERVER，除了SERVER-ID，香港服务器租用，都基本相同，我就不贴了。
1. MYSQLREPLICATE 搭建主从的脚本，这里我搭建了两台从机。
mysqlreplicate –master=root:root@192.168.1.131:3306 –slave=root:root@192.168.1.132:3306;…[root@mysql56-master home]# ./replicate_create# master on 192.168.1.131: … connected.# slave on 192.168.1.132: … connected.# Checking for binary logging on master…# Setting up replication…# …done.# master on 192.168.1.131: … connected.# slave on 192.168.1.133: … connected.# Checking for binary logging on master…# Setting up replication…# …done.
2. mysqlrplcheck 检查主从的运行情况。

3. mysqlrplshow. 显示主从的架构。
[root@mysql56-master home]# mysqlrplshow –master=root:root@192.168.1.131:3306 –discover-slaves-login=root:root -v# master on 192.168.1.131: … connected.# Finding slaves for master: 192.168.1.131:3306# Replication Topology Graph192.168.1.131:3306 (MASTER)|+— 192.168.1.132:3306 [IO running: Yes] – (SLAVE)|+— 192.168.1.133:3306 [IO running: Yes] – (SLAVE)[root@mysql56-master home]#
4. mysqlfailover. 监视主从健康状态。

5. mysqlrpladmin. 对主从进行管理。
