案例十：shell編寫nginx服務啟動程式
阿新 • • 發佈：2019-07-15
| 使用原始碼包安裝的Nginx沒辦法使用"service nginx start"或"/etc/init.d/nginx start"進行操作和控制，所以寫了以下的服務控制指令碼。 |
選項有：
start 啟動 stop 停止 reload 過載 restart 重啟 status 狀態 test 檢查配置檔案
指令碼一
建立指令碼檔案並新增執行許可權
touch /etc/init.d/nginx chmod +x /etc/init.d/nginx
編寫指令碼內容
#!/bin/bash
# chkconfig: - 85 15
# description: Nginx server control script
# processname: nginx
# config file: /usr/local/nginx/conf/nginx.conf
# pid file: /usr/local/nginx/logs/nginx.pid
#
# eastmoney public tools
# version: v1.0.0
# create by XuHoo, 2016-9-14

# source function library
. /etc/rc.d/init.d/functions
NGINX_NAME="nginx"
NGINX_PROG="/usr/local/sbin/nginx"
NGINX_PID_FILE="/usr/local/nginx/logs/nginx.pid"
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
NGINX_LOCK_FILE="/var/lock/subsys/nginx.lock"
# check current user
[ "$USER" != "root" ] && exit 1
start() {
status
if [[ $? -eq 0 ]]; then
echo $"Nginx (PID $(cat $NGINX_PID_FILE)) already started."
return 1
fi
echo -n $"Starting $NGINX_NAME: "
daemon $NGINX_PROG -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $NGINX_LOCK_FILE
return $retval
}
stop() {
status
if [[ $? -eq 1 ]]; then
echo "Nginx server already stopped."
return 1
fi
echo -n $"Stoping $NGINX_NAME: "
killproc $NGINX_PROG
retval=$?
echo
[ $retval -eq 0 ] && rm -f $NGINX_LOCK_FILE
return $retval
}
restart() {
stop
sleep 1
start
retval=$?
return $retval
}
reload() {
echo -n $"Reloading $NGINX_NAME: "
killproc $NGINX_PROG -HUP
retval=$?
echo
return $retval
}
status() {
netstat -anpt | grep "/nginx" | awk '{print $6}' &> /dev/null
if [[ $? -eq 0 ]]; then
if [[ -f $NGINX_LOCK_FILE ]]; then
return 0
else
return 1
fi
fi
return 1
}
_status() {
status
if [[ $? -eq 0 ]]; then
state=`netstat -anpt | grep "/nginx" | awk '{ print $6 }'`
echo $"Nginx server status is: $state"
else
echo "Nginx server is not running"
fi
}
test() {
$NGINX_PROG -t -c $NGINX_CONF_FILE
retval=$?
return $retval
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
status)
_status
;;
test)
test
;;
*)
echo "Usage: { start | stop | reload | restart | status | test }"
exit 1
esac將指令碼新增到系統服務並設定開機啟動
chkconfig --add nginx chkconfig --level 3 nginx on
指令碼二
[root@localhost ~]# cd /usr/local/nginx/conf/ [root@localhost conf]# ls fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
備份主配置檔案
[root@localhost conf]# cp nginx.conf nginx.conf.origin [root@localhost conf]# vim nginx.conf 去除#pid logs/nginx.pid;前面#號
[root@localhost conf]# netstat -anpt | grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19108/nginx [root@localhost conf]# kill -3 19108 [root@localhost conf]# netstat -anpt | grep 80 [root@localhost conf]# nginx [root@localhost conf]# netstat -anpt | grep 80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 19864/nginx [root@localhost conf]# cd ../logs/ [root@localhost logs]# ls access.log error.log nginx.pid [root@localhost logs]# cat nginx.pid 19864
編輯寫服務指令碼
[root@localhost ~]# vim /etc/init.d/nginx 可以使用的選項有： start 啟動 stop 停止 reload 過載 restart 重啟 status 狀態 test 檢查配置檔案
#!/bin/bash #chkconfig: 2345 99 20 #description:Nginx Server Control Scripts shell PROG="/usr/local/nginx/sbin/nginx" PIDF="/usr/local/nginx/logs/nginx.pid" case "$1" in start) if [ -f $PIDF ]; then echo "Nginx正在執行…" else $PROG fi ;; stop) if [ -f $PIDF ]; then kill -3 $(cat $PIDF) rm -f $PIDF else echo "Nginx正在停止…" fi ;; restart) $0 stop $0 start ;; reload) if [ -f $PIDF ]; then kill -1 $(cat $PIDF) else echo "Nginx正在停止…重新載入" fi ;; status) if [ -f $PIDF ]; then echo "Nginx正在執行" else echo "Nginx停止" fi ;; *) echo "Usage: $0 (start|stop|restart|reload|status)" exit 1 esac exit 0
指令碼檔案並新增執行許可權
[root@localhost ~]# chmod +x /etc/init.d/nginx
將指令碼新增到系統服務並設定開機啟動
[root@localhost ~]# chkconfig --add nginx
新增為服務啟動項
[root@localhost ~]# chkconfig --list nginx
nginx 0:關閉 1:關閉 2:啟用 3:啟用 4:啟用 5:啟用 6:關閉
[root@localhost ~]# chkconfig --level 3 nginx on
測試指令碼是否能夠執行
[root@localhost ~]# service nginx start
Nginx正在執行…
[root@localhost ~]# service nginx restart
[root@localhost ~]# service nginx stop
[root@localhost ~]# service nginx stop
Nginx正在停止…
[root@localhost ~]# service nginx start
[root@localhost ~]# service nginx status
