10.Mysql-router

mysql-router是一个轻量级的中间间，可以做mysql的故障自动转移以及读写分离功能

1.官网下载mysql-router二进制包

2.主机介绍：

 

3.创建目录

>>mkdir  -p  /var/log/mysqlrouter         :日志目录

>>mkdir -p /etc/mysqlrouter/mysqlrouter.conf  :这个是配置文件

[root@node04 mysqlrouter]# cat mysqlrouter.conf 
[default]
logging_folder=/var/log/mysqlrouter

[logger]
leverl=info

[routing:failover]
bind_address=0.0.0.0
bind_port=7001
max_connections=1024
mode=read-write
destinations=192.168.11.4:3307,192.168.11.5:3307

[routing:balancing]
bind_address=0.0.0.0
bind_port=7002
max_connections=1024
mode=read-only
destinations=192.168.11.5:3307,192.168.11.6:3307

4.启动

mysqlrouter --config=/xxxx/mysqlrouter.conf

可以用启动脚本进行启动    

说明：7001端口是故障自动切换端口以及可读写

　　　7002端口是负载均衡端口，可以实现负载均衡效果，但是只能读，不能写

5.效果如下：

[root@node04 bin]# ./mysql -umysqlrouter -p123 -h192.168.11.7 -P7002 -e 'select @@server_id'
mysql: [Warning] Using a password on the command line interface can be insecure.
