自动开关ECS及对应服务   这两天,及今天加班,完成了一个对我来说蛮大工作量的任务,一条龙服务之:关服务,关ECS,开ECS(配置开机自启),检查服务,检查网页可用性。   不难,但比较繁琐~~ = =,因为我想尽量把代码写得好修改,复用率高点,也就是真正部署到生产环境(共4台)服务器能尽量把写好的脚本,稍微改一下就能部署。 先放效果图(方便不需要的读者直接绕路,哈哈哈),然后再贴代码(调得吐血 = =) 大致说下测试环境:   共2台服务器,1台A部署有nginx、tomcat、jar包、mongo(实际上线上是分了4台服务器),1台作为管理端B,用来对A进行一系列骚操作的。 一、效果图 测试前: 1、未动A之前,跑着一堆服务 在晚上9点41分的时候,我们检查下服务: ps aux |egrep "nginx|mongo|java|tomcat" |grep -v grep

 2、控制端B设置定时任务

已配置ssh免秘钥登陆A

 

3、效果依次如下: 

(1)服务关

对应脚本:stop_allservices.进去A,人眼检查下,记得留意date输出的时间

 (2)ECS停和开

对应脚本:power_off.py 和power_on.py

 (3)开机后检查服务

对应脚本:check_services.sh

首次检查是表示随开机自启的服务,确实跑起来了,不然重启一次,不行再报警

  (4)网站首页检查可用性

对应脚本:check_page.sh

、脚本

1、关停服务脚本:stop_allservices.sh

该脚本在A服务器上,是B机器,ssh远程A执行的

11 # 检查服务是否已关掉,没关掉就发告警
12 check_service() {
13   port=$2
14   listenport=`/usr/bin/lsof -i:${port} |grep -v COMMAND | awk '{print $2}'`
15 
16   n=`ps aux |grep $1 | grep -v grep | wc -l`
17   if [ $n -gt 1 ];
18   then
19     msg="Fail:$1\t服务没停,请手动关停!"
20     #echo $msg
21     curl_ding $msg
22   else
23     msg="Success:\t$1\t服务已关闭!"
24     curl_ding $msg
25   fi    
26 
27 }
28 
29 curl_ding() {
30   msg=$1
31   echo $msg
32   TOKEN="钉钉机器人"
33   PHONE="我的手机号"
34   DATE=`date +%F_%T`
35   curl -H "Content-Type:application/json" -X POST --data '{"msgtype":"text","text":{"content":"当前时间:'$DATE'\n'$msg'"} , "at": {"atMobiles": ['${PHONE}' ], "isAtAll": false}}' ${TOKEN} > /dev/null 2>&1
36 }
37 
38 
39 ## 1、关nginx
40 ps aux | grep nginx |grep master |awk '{print $2}' | xargs kill -9
41 pkill nginx
42 #sleep 4
43 check_service nginx 80
44 
45 ## 2、后端jar包
46 /usr/bin/lsof -i:{jar包运行端口} |grep -v COMMAND | awk '{print $2}' | xargs kill -9
47 sleep 5
48 check_service {jar包关键字名} {jar包运行端口} 
49 
50 ## 3、tomcat
51 /home/{系统用户}/app/{tomcat项目名}/bin/catalina.sh stop
52 #sleep 5
53 /usr/bin/lsof -i:{tomcat监听端口} |grep -v COMMAND | awk '{print $2}' | xargs kill -9
54 
55 check_service tomcat {tomcat监听端口}
56 
57 
58 ## 4、mongo
59 mongopid=`ps aux |grep mongo |grep -v grep |awk '{print $2}'`
60 sudo kill -9 ${mongopid}
61 
62 check_service mongo {mongo监听端口}

2、关停ECS和开启ECS:power_off.py 和 power_on.py

 55 }
 56 
 57 
 58 ## 1、开nginx
 59 # 开机已自启一次
 60 # 1.1 首次检查
 61 check_service nginx {nginx监听端口}
 62 Nginx_Status=`echo $?`
 63 if [ $Nginx_Status != 0 ]; then

 65    /home/{系统用户}/nginx/sbin/nginx &
 66    sleep 5
 67    # 1.3 检查第二次,还没起来就报警
 68    check_service2 nginx {nginx监听端口}
 69 fi
 70 
 71 ## 2、开后端:jar
 72 # 2.1 首次检查
 73 check_service {java包关键字} {java监听端口}
 74 Jar_Status=`echo $?`
 75 if [ $Jar_Status != 0 ]; then
 76   # 2.2 尝试重启
 77   sh /home/{系统用户}/scripts/{启动后端服务}.sh {java包关键字}.jar
 78   sleep 10
 79 
 80   # 2.3 二次检查
 81   check_service2 {java包关键字} {java监听端口}
 82 fi
 83 
 84 ## 3、后端:tomcat
 85 # 3.1 首次检查
 86 check_service tomcat {tomcat监听端口}
 87 Tomcat_Status=`echo $?`
 88 if [ $Tomcat_Status != 0 ]; then
 89   /home/{系统用户}/app/{tomcat项目关键字}/bin/catalina.sh start
 90   sleep 5
 91   check_service2 tomcat {tomcat监听端口}
 92  
 93 fi
 94 
 95 ## 4、开中间件:mongo
 96 check_service mongo {mongo监听端口}
 97 Mongo_Status=`echo $?`
 98 if [ $Mongo_Status != 0 ]; then
 99   sudo /home/{系统用户}/mongodb/bin/mongod -f /home/{系统用户}/mongodb/conf/mongodb.conf --logappend
100   sleep 3
101   check_service2 mongo {mongo监听端口}
102 fi

4、网站可用性脚本:check_page.sh

 1 #!/bin/bash
 2 
 3 #######################################################
 4 # $Name:        check_page.sh
 5 # $Version:     v1.0
 6 # $Function:    检查xx系统访问地址

 8 #######################################################
 9 
10 
11 check_url() {
12   checkurl=$1
13   status=`curl -I -m 10 -o /dev/null -s -w %{http_code} ${checkurl}`
14 
15   if [ $2 == 'ABC' ];
16   then 
17      keyword="xxx平台"       
18   elif  [ $2 == 'CDE' ];
19   then
20      keyword="xxx系统"
21   else
22      keyword="xxx后端"   
23   fi
24 
25   #不返回200,不正常
26   if [ $status -ne 200 ]; 
27   then 
28      msg="$keyword:访问不正常(非200状态码)"
29   else
30      msg="$keyword:访问正常"
31   fi
32   #发通知
33   curl_ding $msg
34 }
35 
36 curl_ding() {
37   msg=$1
38   #echo $msg
39   TOKEN="钉钉机器人"
40   PHONE="我的手机号码"
41   DATE=`date +%F_%T`
42   curl -H "Content-Type:application/json" -X POST --data '{"msgtype":"text","text":{"content":"当前时间:'$DATE'\n'$msg'"} , "at": {"atMobiles": ['${PHONE}' ], "isAtAll": false}}' ${TOKEN} > /dev/null 2>&1
43 }
44 
45 
46 url_ABC='XXXXX'
47 url_CDE='XXXXX'
48 url_EFG='XXXXX'
49 
50 check_url $url_ABC ABC
51 check_url $url_CDE CDE
52 check_url $url_EFG EFG

三、注意点

 最后讲下坑爹的一个点,该脚本:check_services.sh 有个非常难看的:

msg="Success:\t$1\t服务已正常开启(第二次检查,重启过一次)"
因为为了好看,我想输出到钉钉用空格,但是被强制当成多个参数传递给shell的函数,搞到被截断。这里用用tab键分开,不然会变成这样,后面的字都没了  
   没有空格又丑,将就下看,哈哈哈

 最后写完博客,我就把A测试机关掉并释放,不然按量购买的机器每小时8毛那样扣费

 Ada,我的爱机~~~洗洗睡~
