supervisor安装部署和使用实例

Supervisord是用Python实现的一款非常实用的进程管理工具,类似于monit,monit和supervisord的一个比较大的差异是supervisord管理的进程必须由supervisord来启动,monit可以管理已经在运行的程序;supervisord还要求管理的程序是非daemon程序,supervisord会帮你把它转成daemon程序,因此如果用supervisord来管理nginx的话,必须在nginx的配置文件里添加一行设置daemon off让nginx以非daemon方式启动。(此段话引用链接:http://feilong.me/2011/03/monitor-processes-with-supervisord)

 

注意:如果用supervisorctlstart nginx启动nginx显示错误nginx: ERROR(abnormal termination),查看日志说是nginx已经启动,这就是因为nginx本身是daemon程序,要在nginx的配置文件中把它转为非daemon程序.

 

1.Supervisor安装:

1 # 安装  
2 easy_install supervisor 

也可采用离线安装的方式:

 

安装python
安装meld3-0.6.8.tar.gz

安装elementtree-1.2.6-20050316.tar.gz
安装supervisor-3.0a12.tar.gz

官方安装文档:
http://supervisord.org/installing.html

依赖软件:

1 setuptools (latest) from http://pypi.python.org/pypi/setuptools.  
2 meld3 (latest) from http://www.plope.com/software/meld3/.  
3 elementtree (latest) from http://effbot.org/downloads#elementtree.  
2.生成默认配置文件:
1 # 生成默认配置文件  
2 echo_supervisord_conf > /etc/supervisord.conf  
3 mkdir /etc/supervisord.conf.d  

3.修改配置文件

1 include区段修改为:  
2 [include]  
3 files = /etc/supervisord.conf.d/*.conf  
1 如需要访问web控制界面,inet_http_server区段修改为:  
2 [inet_http_server]  
3 port=0.0.0.0:9001  
4 username=username ; 你的用户名  
5 password=password ; 你的密码  
 
1 每个需要管理的进程分别写在一个文件里面,放在/etc/supervisord.conf.d/目录下,便于管理。例如:test.conf  
2 [program:sqlparse]  
3 directory = /var/local/python  
4 command = /use/bin python test.py  

4.把supervisord服务设为开机自启动,把下面程序复制下来生成supervisord文件放到/etc/init.d/目录下面:

CentOS环境下:

25         daemon --pidfile $pidfile supervisord -c /etc/supervisord.conf  
26         RETVAL=$?  
27         echo  
28         [ $RETVAL -eq 0 ] && touch ${lockfile}  
29 }  
30   
31 stop()  
32 {  
33         echo -n $"Shutting down $prog: "  
34         killproc -p ${pidfile} /usr/bin/supervisord  
35         RETVAL=$?  
36         echo  
37         if [ $RETVAL -eq 0 ] ; then  
38                 rm -f ${lockfile} ${pidfile}  
39         fi  
40 }  
41   
42 case "$1" in  
43   
44   start)  
45     start  
46   ;;  
47   
48   stop)  
49     stop  
50   ;;  
51   
52   status)  
53         status $prog  
54   ;;  
55   
56   restart)  
57     stop  
58     start  
59   ;;  
60   
61   *)  
62     echo "Usage: $0 {start|stop|restart|status}"  
63   ;;  
64   
65 esac

用root用户执行下面命令把supervisord服务设为开机自启动:

 

CentOS系统下:

1 chmod +x /etc/init.d/supervisord  
2 chkconfig supervisord on  
3 service supervisord start


Ubuntu系统下:

1 chmod +x /etc/init.d/supervisord  
2 update-rc.d supervisord defaults

 

5.supervisord管理

Supervisord安装完成后有两个可用的命令行supervisor和supervisorctl,命令使用解释如下:

  • supervisord,初始启动Supervisord,启动、管理配置中设置的进程。
  • supervisorctl stop programxxx,停止某一个进程(programxxx),programxxx为[program:chatdemon]里配置的值,这个示例就是chatdemon。
  • supervisorctl start programxxx,启动某个进程
  • supervisorctl restart programxxx,重启某个进程
  • supervisorctl stop groupworker: ,重启所有属于名为groupworker这个分组的进程(start,restart同理)
  • supervisorctl stop all,停止全部进程,注:start、restart、stop都不会载入最新的配置文件。
  • supervisorctl reload,载入最新的配置文件,停止原有进程并按新的配置启动、管理所有进程。
  • supervisorctl update,根据最新的配置文件,启动新配置或有改动的进程,配置没有改动的进程不会受影响而重启。
  • 注意:显示用stop停止掉的进程,用reload或者update都不会自动重启。

7.管理实例

7.1.测试一个简单的python程序:

在/etc/supervisord.conf.d/目录下生成testsupervisor.conf文件

1 [program:testsupervisor]  
2 directory = /opt/testsupervisor  
3 command = /usr/local/bin/python testsupervisor.py  
4 priority=1  
5 numprocs=1  
6 autostart=true  
7 autorestart=true  

directory表示testsupervisor.py所在的工作目录

command表示执行的命令,注意python要用绝对路径:/usr/local/bin/python

priority表示优先级,用supervisord管理的程序会按优先级从高到低依次启动,数字越多,优先级越高

autostart表示自动启动

autorestart表示自动重启

 

7.2.用supervisord管理 redis程序:

在/etc/supervisord.conf.d/目录下生成redis.conf文件

 1 [program:redis]  
 2 directory=/usr/local/src/redis-2.6.16  
 3 command=/usr/local/src/redis-2.6.16/src/redis-server redis.conf  
 4   
 5 stdout_logfile=/tmp/redis_access.log  
 6 stderr_logfile=/tmp/redis_error.log  
 7 autostart=true  
 8 autorestart=true  
 9 startsecs=10  
10   
11 ; Need to wait for currently executing tasks to finish at shutdown.  
12 ; Increase this if you have very long running tasks.  
13 stopwaitsecs = 600  
14   
15 ; if rabbitmq is supervised, set its priority higher  
16 ; so it starts first  
17 priority=10  


7.3.用supervisord管理nginx程序,因为nginx默认就是以daemon方式启动的,所以如果用supervisord来管理nginx的话,必须在nginx的配置文件里添加一行设置daemon off让nginx以非daemon方式启动。(supervisord还要求管理的程序是非daemon程序,supervisord会帮你把它转成daemon程序)

 

在/usr/local/nginx/conf/目录下面修改nginx.conf文件:

 
 1 worker_processes 2;  
 2 daemon off;  
 3 events {  
 4 #use epoll;  
 5 worker_connections 1024;  
 6 }  
 7 http{  
 8         #gzip on;  
 9         #gzip_min_length  100;  
10         #gzip_buffers     4 16k;  
11         #gzip_http_version 1.0;  
12         #gzip_comp_level 2;  
13         #gzip_types       text/plain application/x-javascript text/css application/xml;  
14         #gzip_vary on;  
15   
16         upstream 192.168.56.11 {  
17         #这里指定多个源服务器,ip:端口,80端口的话可写可不写    
18                 server 127.0.0.1:8003;  
19                 server 127.0.0.1:8004;  
20                 server 127.0.0.1:8005;  
21                 server 127.0.0.1:8006;  
22   
23         }  
24         server {  
25                 listen 8010;  
26                 location / {  
27                         #rewrite ^/smmp/servletsendmoremsg\.do$ /send last;  
28                         proxy_redirect off;  
29                         proxy_set_header Host    $host;  
30                         proxy_set_header X-Forwarded-For $remote_addr;  
31                         proxy_pass http://192.168.56.11;  
32   
33                 }  
34   
35         }  
36   
37 #       server {  
38 #               listen 443;  
39 #                ssl                  on;  
40 #               ssl_certificate      server.crt;  
41 #               ssl_certificate_key  server.key;

46 #               ssl_ciphers  HIGH:!aNULL:!MD5;  
47 #               ssl_prefer_server_ciphers   on;  
48 #               location / {  
49 #                        proxy_redirect off;  
50 #                        proxy_set_header Host    $host;  
51 #                        proxy_set_header X-Forwarded-For $remote_addr;  
52 #                        proxy_pass http://192.168.56.11;  
53 #  
54 #                }  
55 #                 
56 #       }    
57 }

25 ;numprocs=2  
 

7.6.用supervisord管理venus服务(启了四个进程):

在/etc/supervisord.conf.d/目录下生成venux.conf文件

 1 [program:venus-8003]  
 2 directory=/usr/local/workspace_eclipse3.7.2/venus  
 3 command=/usr/local/bin/python main.py --port=8003

18   
19 [program:venus-8005]  
20 directory=/usr/local/workspace_eclipse3.7.2/venus  
21 command=/usr/local/bin/python main.py --port=8005  
22 stdout_logfile=/tmp/venus_8005.log  
23 stderr_logfile=/tmp/venus_8005.log  
24 autostart=true  
25 autorestart=true  
26 priority=52  
27   
28 [program:venus-8006]

7.7.用supervisord管理接收短信的服务:

在/etc/supervisord.conf.d/目录下生成receiver_cmpp.conf文件

 1 [program:receiver-cmpp]  
 2 directory=/usr/local/workspace_eclipse3.7.2/sms_tool  
 3 command=/usr/local/bin/python receiver_cmpp.py

14   
15 ; if rabbitmq is supervised, set its priority higher  
16 ; so it starts first  
17 priority=21  

 

在/etc/supervisord.conf.d/目录下添加新的配置文件后,执行命令:

1 supervisorctl update  


就会把新添加的服务启动起来,且不会影响正在运行的 服务。
