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
?
| 1 2 3 4 5 6 7 8 9 10 11 12 | . /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
?
| 1 | [root@localhost] # vim /etc/init.d/nginx |
以下是脚本内容
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 | #!/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.conf nginxd= /usr/local/nginx/sbin/nginx nginx_config= /usr/local/nginx/conf/nginx .conf nginx_pid= /usr/local/nginx/logs/nginx .pid RETVAL=0 prog= "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 1 fi 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" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $ "Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $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
?
| 1 | [root@localhost] # chmod a+x /etc/init.d/nginx |
(a+x ==> all user can execute 所有用户可执行)
这样在控制台就很容易的操作nginx了:查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…
?
| 1 | usage : nginx {start|stop|restart|reload|status|help} |
如果修改了nginx的配置文件nginx.conf,也可以使用上面的命令重新加载新的配置文件并运行,可以将此命令加入到rc.local文件中,这样开机的时候nginx就默认启动了
加入到rc.local文件中
?
| 1 | [root@localhost] # vi /etc/rc.local |
加入一行 /etc/init.d/nginx start 保存并退出,下次重启会生效。
注意
如果开机后发现自启动脚本没有执行,你要去确认一下rc.local这个文件的访问权限是否是可执行的,因为rc.local默认是不可执行的。
修改rc.local访问权限,增加可执行权限
?
| 1 | [root@localhost] # chmod +x /etc/rc.d/rc.local |
现在重启后,自启动脚本就能正常执行了。
可以通过以下命令来查看nginx进行的运行情况
?
| 1 | [root@localhost] # ps aux | grep nginx |
