關于在centos7中設置nginx開機自啟動,我們可以通過編寫開機自啟動shell腳本來解決。
測試環境
操作系統:centos7 64位 1611
nginx版本: 1.11.10
本機nginx安裝時的配置參數
./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
編寫腳本
[root@localhost]#?vim?/etc/init.d/nginx
以下是腳本內容
#!/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.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.

*對于shell腳本中的部分文件路徑請修改成你主機上nginx的相應路徑,例如:? nginxd=/usr/local/nginx/sbin/nginx? nginx_config=/usr/local/nginx/conf/nginx.conf? nginx_pid=/usr/local/nginx/logs/nginx.pid? 以上都是本測試機nginx的相應路徑? 還有nginx的pid默認路徑是nginx安裝目錄的logs/nginx.pid里。
設置文件的訪問權限
[root@localhost]#?chmod?a+x?/etc/init.d/nginx
(a+x ==> all user can execute? 所有用戶可執行)
這樣在控制臺就很容易的操作nginx了:查看nginx當前狀態、啟動nginx、停止nginx、重啟nginx…
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載新的配置文件并運行,可以將此命令加入到rc.local文件中,這樣開機的時候nginx就默認啟動了
加入到rc.local文件中
[root@localhost]#?vi?/etc/rc.local
加入一行? /etc/init.d/nginx start??? 保存并退出,下次重啟會生效。
注意
如果開機后發現自啟動腳本沒有執行,你要去確認一下rc.local這個文件的訪問權限是否是可執行的,因為rc.local默認是不可執行的。
修改rc.local訪問權限,增加可執行權限
[root@localhost]#?chmod?+x?/etc/rc.d/rc.local
現在重啟后,自啟動腳本就能正常執行了。
可以通過以下命令來查看nginx進行的運行情況
[root@localhost]#?ps?aux?|?grep?nginx
