先配置好mycat并且启动mycat
[root@mycat05 software]# cd /usr/local/src/haproxy-1.5.18/
[root@mycat05 haproxy-1.5.18]# uname -r
3.10.0-957.el7.x86_64
[root@mycat05 haproxy-1.5.18]# make TARGET=linux310 PREFIX=/usr/local/haproxy ARCH=x86_64
global log 127.0.0.1 local0 #log 127.0.0.1 local1 notice #log loghost local0 info maxconn 4096 chroot /usr/local/haproxy pidfile /usr/data/haproxy/haproxy.pid uid 99 gid 99 daemon #debug #quiet defaults log global mode tcp option abortonclose option redispatch retries 3 maxconn 2000 timeout connect 5000 timeout client 50000 timeout server 50000 listen proxy_status bind :48066 mode tcp balance roundrobin server mycat_1 192.168.140.128:8066 check inter 10s server mycat_2 192.168.140.127:8066 check inter 10s frontend admin_stats bind :7777 mode http stats enable option httplog maxconn 10 stats refresh 30s stats uri /admin stats auth admin:123123 //登陆账户and密码 stats hide-version stats admin if TRUE
在HAProxy主机上执行（192.168.199.174HA的主机地址）
[root@mycat05 haproxy-1.5.18]# mysql -umycat -p123456 -h 192.168.199.174 -P 48066
