PHP-FPM 服务

下载文件php-fpm.sh
注意配置文件：sudo vim /usr/local/php-7.2/etc/php-fpm.conf

务必开启配置文件的pid路径：pid = run/php-fpm.pid 否则会报错：no pid file found - php-fpm is not running ?

CP到默认开启的服务脚本：

sudo cp php-fpm.sh  /etc/init.d/php-fpm

给予权限：
```
sudo chmod +x /etc/init.d/php-fpm
```

Nginx 服务

第一种安装方式
- 查看当前nginx是否已经在开机启动项里面:
```
ls /etc/rc*
```
- 如何安装
```
#使用wget -O 下载并以不同的文件名保存 
sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
# 给与权限   
sudo chmod +x /etc/init.d/nginx
# 设置为启动项
sudo update-rc.d nginx defaults
```
- 需要修改的地方：
  - 1、NGINXPATH=${NGINXPATH:-/opt/openresty/nginx} 修改为自己的路径
  - 2、PIDSPATH=${PIDSPATH:-$NGINXPATH/logs} pid文件路径
    
    如果在配置文件修改为：pid /run/nginx.pid;
    PIDSPATH=${PIDSPATH:-$NGINXPATH/logs}修改为：PIDSPATH="/run"

第二种安装方式

```
sudo vim /etc/init.d/nginx

```

开启服务

sudo service nginx restart

 * Stopping Nginx Server...      [ OK ] 
 * Starting Nginx Server...      [ OK ]

Ubuntu 16.04.2 LTS 启动脚本

PHP-FPM 服务

php-fpm.sh脚本代码同上
注意，需要重新加载服务：
```
sudo systemctl daemon-reload
```
开启服务
```
sudo systemctl start php-fpm.service
```
停止服务
```
sudo systemctl stop php-fpm.service
```
重启服务
```
sudo systemctl restart php-fpm.service
```

Nginx 服务

Debian/Ubuntu Nginx init Script

[1]通常情况下，如果你从存储库安装Nginx，这个初始化脚本已经包含在内。但是，如果您从源代码安装，或者没有使用标准路径，您可能需要这个。
[2]如果发现停止/重新启动等不起作用，则您的pid文件位置可能不正确。您可以将其设置在nginx.conf中，也可以在此处更改init脚本以指向正确的pid位置
