Nginx开机启动

开机启动

在/etc/init.d目录创建nginx文件，并输入以下内容

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server

注：修改如下两项内容为自己nginx相应路径

# 你启动nginx的文件位置
nginx="/usr/local/nginx/sbin/nginx"

# nginx的配置文件位置
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"

给nginx文件添加可执行权限

chmod +x /etc/init.d/nginx

加入开机启动

# 添加到系统服务
chkconfig --add nginx
# 设置为开机自启动
chkconfig nginx on

chkconfig --add命令会生成/run/systemd/generator.late/nginx.service文件，内容如下：

# Automatically generated by systemd-sysv-generator

[Unit]
Documentation=man:systemd-sysv-generator(8)
SourcePath=/etc/rc.d/init.d/nginx
Description=SYSV: NGINX is an HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server
Before=shutdown.target
Conflicts=shutdown.target

[Service]
Type=forking
Restart=no
TimeoutSec=5min
IgnoreSIGPIPE=no
KillMode=process
GuessMainPID=no
RemainAfterExit=no
# chkconfig --add命令默认生成nginx.pid的位置(还未找到方法能修改)，所以需要在编译安装nginx时指定pid文件位置为如下，否则启动会报pid文件找不到
PIDFile=/var/run/nginx.pid
ExecStart=/etc/rc.d/init.d/nginx start
ExecStop=/etc/rc.d/init.d/nginx stop
ExecReload=/etc/rc.d/init.d/nginx reload

设置开机自启动

# 重载配置文件
sudo systemctl daemon reload
# 设置开机启动
sudo systemctl enable nginx.service
# 启动
sudo systemctl start nginx.service
# 停止
sudo systemctl stop nginx.service
# 重启
sudo systemctl restart nginx.service
