使用systemd启动Stunnel，并设置自动重启的方法

操作步骤

运行环境: Centos7

1. 安装stunnel

yum install stunnel

2. 编写systemd配置文件，放到/usr/lib/systemd/system

[Unit]

After=network.target

[Service]
Type=forking
User=root
ExecStart=/usr/bin/stunnel /etc/stunnel/stunnel.conf
Restart=always

[Install]
WantedBy=multi-user.target

参数解释：

• Restart=always 只要不是通过systemctl stop来停止服务，任何情况下都必须要重启服务，默认值为no

3. 启动stunnel

systemctl daemon-reload
systemctl start stunnel

手动启动，停止stunnel的方法

启动

stunnel /etc/stunnel/stunnel.conf

停止

kill `cat /var/run/stunnel.pid`
