详解Centos7中Nginx开机自启动的解决办法

关于在centos7中设置Nginx开机自启动，我们可以通过编写开机自启动shell脚本来解决。

测试环境

操作系统：centos7 64位 1611

Nginx版本： 1.11.10

本机Nginx安装时的配置参数

./configure /--prefix=/usr/local/nginx /--pid-path=/usr/local/nginx/logs/nginx.pid /--lock-path=/var/lock/nginx.lock /--error-log-path=/var/log/nginx/error.log /--http-log-path=/var/log/nginx/access.log /--with-http_gzip_static_module /--http-client-body-temp-path=/var/temp/nginx/client /--http-proxy-temp-path=/var/temp/nginx/proxy /--http-fastcgi-temp-path=/var/temp/nginx/fastcgi /--http-uwsgi-temp-path=/var/temp/nginx/uwsgi /--http-scgi-temp-path=/var/temp/nginx/scgi

编写脚本

[root@localhost]# vim /etc/init.d/nginx

以下是脚本内容

#!/bin/bash# nginx Startup script for the Nginx HTTP Server# it is v.0.0.2 version.# chkconfig: - 85 15# description: Nginx is a high-performance web and proxy server.#       It has a lot of features, but it's not for everyone.# processname: nginx# pidfile: /usr/local/nginx/logs/nginx.pid# config: /usr/local/nginx/conf/nginx.confnginxd=/usr/local/nginx/sbin/nginxnginx_config=/usr/local/nginx/conf/nginx.confnginx_pid=/usr/local/nginx/logs/nginx.pidRETVAL=0prog="nginx"# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ "${NETWORKING}" = "no" ] && exit 0[ -x $nginxd ] || exit 0# Start nginx daemons functions.start() {if [ -e $nginx_pid ];then  echo "nginx already running...."  exit 1fi  echo -n $"Starting $prog: "  daemon $nginxd -c ${nginx_config}  RETVAL=$?  echo  [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx  return $RETVAL}# Stop nginx daemons functions.stop() {    echo -n $"Stopping $prog: "    killproc $nginxd    RETVAL=$?    echo    [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid}# reload nginx service functions.reload() {  echo -n $"Reloading $prog: "  #kill -HUP `cat ${nginx_pid}`  killproc $nginxd -HUP  RETVAL=$?  echo}# See how we were called.case "$1" instart)    start    ;;stop)    stop    ;;reload)    reload    ;;restart)    stop    start    ;;status)    status $prog    RETVAL=$?    ;;*)    echo $"Usage: $prog {start|stop|restart|reload|status|help}"    exit 1esacexit $RETVAL:wq 保存并退出

*对于shell脚本中的部分文件路径请修改成你主机上nginx的相应路径，例如：  nginxd=/usr/local/nginx/sbin/nginx  nginx_config=/usr/local/nginx/conf/nginx.conf  nginx_pid=/usr/local/nginx/logs/nginx.pid  以上都是本测试机nginx的相应路径  还有nginx的pid默认路径是nginx安装目录的logs/nginx.pid里。

设置文件的访问权限

[root@localhost]# chmod a+x /etc/init.d/nginx  

(a+x ==> all user can execute  所有用户可执行)
