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. +-------------+ | @@server_id | +-------------+ | 67 | +-------------+ [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. +-------------+ | @@server_id | +-------------+ | 57 | +-------------+ [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. +-------------+ | @@server_id | +-------------+ | 67 | +-------------+ [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. +-------------+ | @@server_id | +-------------+ | 57 | +-------------+
