⑥.haproxy定义子配置并生效

1.定义配置

[root@proxy01 haproxy]#  cat /etc/haproxy/conf.d/app.oldxu.net.cfg 
frontend app_web
    bind *:8899
    mode http
    use_backend app_servers
    
backend app_servers
    balance roundrobin
    server web1 172.16.1.7:8888 check inter 3000 fall 2 rise 5
    server web2 172.16.1.8:8888 check inter 3000 fall 2 rise 5

2.haproxy启动方式：

[root@proxy01 haproxy]# cat  /usr/lib/systemd/system/haproxy.service
[Unit]
Description=HAProxy Load Balancer
After=network-online.target
Wants=network-online.target

[Service]
EnvironmentFile=-/etc/sysconfig/haproxy
Environment="CONFIG=/etc/haproxy/haproxy.cfg" "PIDFILE=/run/haproxy.pid"
Environment="CONFIG_D=/etc/haproxy/conf.d/"


ExecStartPre=/usr/sbin/haproxy -f $CONFIG -f $CONFIG_D -c -q $OPTIONS
ExecStart=/usr/sbin/haproxy -Ws -f $CONFIG -f $CONFIG_D -p $PIDFILE $OPTIONS
ExecReload=/usr/sbin/haproxy -f $CONFIG -f $CONFIG_D -c -q $OPTIONS
ExecReload=/bin/kill -USR2 $MAINPID
KillMode=mixed
SuccessExitStatus=143
Type=notify

[Install]
WantedBy=multi-user.target


[root@proxy01 haproxy]# systemctl daemon-reload
[root@proxy01 haproxy]# systemctl restart haproxy
[root@proxy01 haproxy]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

PS: #创建子配置文件，注意：必须为cfg后缀非.开头的配置文件
