### 解决： ###

创建/var/lib/haproxy/stats文件

[root@ldap1 ~]# mkdir -p /var/lib/haproxy
    [root@ldap1 ~]# touch /var/lib/haproxy/stats

再次启动，成功

[root@ldap1 ~]# systemctl start haproxy
    [root@ldap1 ~]# ps -ef | grep -i haproxy
    root     14637     1  0 16:38 ?        00:00:00 /usr/sbin/haproxy -W -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid
