初始化数据库文件:
mysql_install_db --datadir=/var/lib/mysql/3306 --user=mysql
mysql_install_db --datadir=/var/lib/mysql/3307 --user=mysql
mysql_install_db --datadir=/var/lib/mysql/3308 --user=mysql
启动数据库:
mysqld_multi start 3306
mysqld_multi start 3307
mysqld_multi start 3308
查看启动情况:
netstat -tunlp | grep -E '(3306|3307|3308)'

安装Haporxy
apt-get install haproxy
然后vim etc/default/haproxy
修改 ENABLED=0 -> ENABLED=1 保存。
修改haproxy配置文件:
vim /etc/haproxy/haproxy.cfg
# this config needs haproxy-1.1.28 or haproxy-1.2.1
global
log 127.0.0.1 local0
log 127.0.0.1 local1 notice

执行命令:
/etc/init.d/haproxy start
测试结果:
