案例十：shell编写nginx服务启动程序
| 使用源码包安装的Nginx没办法使用"service nginx start"或"/etc/init.d/nginx start"进行操作和控制，所以写了以下的服务控制脚本。 |
选项有：
start 启动 stop 停止 reload 重载 restart 重启 status 状态 test 检查配置文件
脚本一
创建脚本文件并添加执行权限
touch /etc/init.d/nginx chmod +x /etc/init.d/nginx
编写脚本内容
#!/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
将脚本添加到系统服务并设置开机启动
chkconfig --add nginx chkconfig --level 3 nginx on
脚本二
[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
备份主配置文件
[root@localhost conf]# cp nginx.conf nginx.conf.origin [root@localhost conf]# vim nginx.conf 去除#pid logs/nginx.pid;前面#号
[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
编辑写服务脚本
[root@localhost ~]# vim /etc/init.d/nginx 可以使用的选项有： start 启动 stop 停止 reload 重载 restart 重启 status 状态 test 检查配置文件
#!/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正在运行…" 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…重新加载" fi ;; status) if [ -f $PIDF ]; then echo "Nginx正在运行" else echo "Nginx停止" fi ;; *) echo "Usage: $0 (start|stop|restart|reload|status)" exit 1 esac exit 0
脚本文件并添加执行权限
[root@localhost ~]# chmod +x /etc/init.d/nginx
将脚本添加到系统服务并设置开机启动
[root@localhost ~]# chkconfig --add nginx
添加为服务启动项
[root@localhost ~]# chkconfig --list nginx
nginx 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
[root@localhost ~]# chkconfig --level 3 nginx on
测试脚本是否能够执行
[root@localhost ~]# service nginx start
Nginx正在运行…
[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
Nginx正在运行
