剛才安裝了Nginx, 命令需要去sbin目錄執行，比較麻煩，設置下全局命令，就無需進入nginx的sbin目錄執行nginx命令了，過程如下：
1.創建文件
vim /etc/init.d/nginx
2.把下面的代碼粘貼進去
#!/bin/sh # nginx - this script starts and stops the nginx daemin # # chkconfig: - 85 15 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ # proxy and IMAP/POP3 proxy server # processname: nginx # config: /usr/local/nginx/conf/nginx.conf # pidfile: /usr/local/nginx/logs/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/local/nginx/sbin/nginx" prog=$(basename $nginx) NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" lockfile=/var/lock/subsys/nginx start() { [ -x $nginx ] || exit 5 [ -f $NGINX_CONF_FILE ] || exit 6 echo -n $"Starting $prog: " daemon $nginx -c $NGINX_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc $prog -QUIT retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { configtest || return $? stop start } reload() { configtest || return $? echo -n $"Reloading $prog: " killproc $nginx -HUP RETVAL=$? echo } force_reload() { restart } configtest() { $nginx -t -c $NGINX_CONF_FILE } rh_status() { status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart|configtest) $1 ;; reload) rh_status_q || exit 7 $1 ;; force-reload) force_reload ;; status) rh_status ;; condrestart|try-restart) rh_status_q || exit 0 ;; *) echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" exit 2 esac
3.進入目錄
cd /etc/init.d
執行
chmod 755 /etc/init.d/nginx
chkconfig --add nginx
4. 錯誤處理
vim /etc/profile，如下所述
PATH=$PATH:/home/nginx/sbin
export PATHi
執行：source /etc/profile 讓配置文件重新生效一下即可
解決辦法：/home/nginx/sbin/nginx -c /home/nginx/conf/nginx.conf
已解決，命令ok
也可以使用：ln -s /home/nginx/sbin/nginx /usr/local/bin/nginx
5. 全局命令
查看版本：nginx -v
[root@ibk_187 sbin]# nginx -v nginx version: nginx/1.13.4
檢查配置是否正確：nginx -t
[root@ibk_187 sbin]# nginx -t nginx: the configuration file /home/nginx/conf/nginx.conf syntax is ok nginx: configuration file /home/nginx/conf/nginx.conf test is successful
關閉：nginx -s quit
nginx -s stop
啟動
[root@ibk_187 sbin]# cd /home/nginx/sbin/
[root@ibk_187 sbin]# ./nginx
重啟服務器，發現此錯誤
nginx -s reload
nginx: [error] open() "/home/nginx/logs/nginx.pid" failed (2: No such file or directory)
解決方法：
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
使用nginx -c的參數指定nginx.conf文件的位置
[root@localhost nginx]# cd logs/
[root@localhost logs]# ll
看nginx.pid文件已經有了。
