本篇文章给大家分享的是有关maxscale + mariadb5.5如何实现读写分离，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
1、安装
[root@localhost ~]# yum -y localinstall maxscale-2.3.5-1.centos.7.x86_64.rpm
2、添加访问用户
mysql> create user xingzhenxiang identified by '111111';
Query OK, 0 rows affected (0.04 sec)
mysql> grant all privileges on . to xingzhenxiang;
3、格式化密码，没有这么配置密码的时候，好像连接有问题
maxkeys /var/lib/maxscale/
maxpasswd /var/lib/maxscale/ 111111
不同机器得到的格式串不一样

chown maxscale.maxscale /var/lib/maxscale/.secrets
systemctl restart maxscale
4、编辑配置文件
[root@localhost maxscale]# cat /etc/maxscale.cnf
[maxscale]
threads=auto
log_info=1
log_warning=1
[server1]
type=server
address=192.168.204.130

[root@localhost maxscale]#
5、安装sysbench
curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
6、压测
[root@localhost ~]# sysbench /usr/share/sysbench/tests/include/oltp_legacy/oltp.lua --mysql-host=192.168.204.129 --mysql-port=4006 --mysql-user=xingzhenxiang --mysql-password=111111 --oltp-test-mode=complex --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 run
7、我的压测
[root@localhost ~]# sysbench /usr/share/sysbench/tests/include/oltp_legacy/oltp.lua --mysql-host=192.168.204.129 --mysql-port=4006 --mysql-user=xingzhenxiang --mysql-password=111111 --oltp-test-mode=complex --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 run

8、主从状态，内部机制自动识别主从，并不是以server1为主
MaxScale> list servers

-------------------+-----------------+-------+-------------+--------------------
server1 | 192.168.204.130 | 3306 | 0 | Master, Running
server2 | 192.168.204.129 | 3306 | 0 | Slave, Running
