replication-manager for MySQL ha 安装测试笔记

1、配置yum源

[root@mgr1 ~]# cat /etc/yum.repos.d/signal18.repo[signal18]name=Signal18 repositoriesbaseurl=http://repo.signal18.io/centos/$releasever/$basearch/gpgcheck=0enabled=1

2、yum安装过程

3、配置文件修改

[root@mgr1 ~]# find / -name *.toml/etc/replication-manager/cluster.d/cluster01.toml/etc/replication-manager/cluster.d/cluster02.toml[root@mgr1 ~]# vim /etc/replication-manager/cluster.d/cluster01.toml[root@mgr1 ~]# mkdir -p /data/replication-manager[root@mgr1 ~]# mkdir -p /data/share_replication-manager[root@mgr1 ~]# vim /etc/replication-manager/config.toml                                                                                                                  [root@mgr1 ~]# cat /etc/replication-manager/config.toml[Cluster01]title = "Cluster01"db-servers-hosts = "192.168.56.14:3306,192.168.56.15:3306,192.168.56.16:3306"db-servers-prefered-master = "192.168.56.15:3306"db-servers-credential = "orchestrator:123456"db-servers-connect-timeout = 1replication-credential = "orchestrator:123456"failover-mode = "automatic"[Default]monitoring-datadir = "/data/replication-manager"monitoring-sharedir = "/data/share_replication-manager"log-level=1log-file = "/var/log/replication-manager.log"replication-multi-master = falsereplication-multi-tier-slave = falsefailover-readonly-state = truehttp-server = truehttp-bind-address = "0.0.0.0"http-port = "10001"

4、启动

[root@mgr1 ~]# /etc/init.d/replication-manager restartRestarting replication-manager (via systemctl):            [  OK  ][root@mgr1 ~]#

5、切换测试

6、结合中间件maxscale，proxysql

maxscale，proxysql负责读写分离，因为这两个中间件本身就有识别发现主的功能，所以replication-manager负责管理主从failover的主库选举和从库指向新主。发现replication-manager可以对maxscale，proxysql管理，我觉得这个两个中间件主动发现模式已经够用了，不需要被动接收replication-manager发送信息。

7、特别说明：

shutdown的主节点上线后，replication-manager会自动把其加入集群。replication-manager不需要在MySQL节点安装客户端

8、我的环境：

mgr安装的是replication-manageres1-3安装的是MySQL5.7 gtid主从[root@mgr1 maxscale]# cat /etc/hosts127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4::1         localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.56.13 mgr192.168.56.14 es1192.168.56.15 es2192.168.56.16 es3[root@mgr1 maxscale]# [root@es3 bin]# cat /etc/my.cnf |grep -v ^#[mysqld]datadir=/var/lib/mysqlsocket=/var/lib/mysql/mysql.socksymbolic-links=0log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.pidgtid-mode = ONenforce-gtid-consistency = ONlog-slave-updates = ONlog-bin=mysqlbinserver-id=3report_host=es3[root@es3 bin]#
