HAProxy 重启时出错。这是我遇到的错误：

# systemctl status haproxy

【解决方案1】：

由于您使用的是 systemd，因此您应该使用 systemd 单元文件而不是 init.d 脚本。

不知道你是怎么安装haproxy的，可以在haproxy源码目录(contrib/systemd)找到haproxy.service，复制到systemd文件夹下使用。

cp contrib/systemd_haproxy.service /lib/systemd/system/
systemctl daemon-reload
systemctl enable haproxy
systemctl start haproxy
systemctl status haproxy
