linux 部署supervisor 程序管理

介紹：當項目工程越來越大的時候，随着線上部署的伺服器也越來越多，更新、管理起來也會很麻煩，需要在每台伺服器上去啟動腳本，本篇文章會介紹如何部署supervisor來管理服務程序。

一、supervisor監控程序部署

準備工作:需要守護監聽程序的伺服器，例如：192.168.0.121

1.安裝setuptools
yum install python-setuptools -y

2.下載下傳meld3和supervisor
wget https://pypi.python.org/packages/0f/5e/3a57c223d8faba2c3c2d69699f7e6cfdd1e5cc31e79cdd0dd48d44580b50/meld3-1.0.1.tar.gz#md5=2f045abe0ae108e3c8343172cffbe21d

wget https://pypi.python.org/packages/31/7e/788fc6566211e77c395ea272058eb71299c65cc5e55b6214d479c6c2ec9a/supervisor-3.3.3.tar.gz#md5=0fe86dfec4e5c5d98324d24c4cf944bd

3.解壓安裝meld3和supervisor
tar xf meld3-1.0.1.tar.gz
cd meld3-1.0.1
python setup.py install
cd ../
tar xf supervisor-3.3.3.tar.gz
cd supervisor-3.3.3
python setup.py install 

4.生成supervisord配置檔案
mkdir /etc/supervisor
cd /etc/supervisor
echo_supervisord_conf > supervisord.conf

5.修改配置開啟遠端web頁面通路,去掉前面的;号
[inet_http_server]         ; inet (TCP) server disabled by default
 port=0.0.0.0:9001        ; ip_address:port specifier, *:port for all iface
 username=user              ; default is no username (open server)
 password=123               ; default is no password (open server)

6.啟動服務并通路頁面
/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
http://ip位址:9001 通路位址之後頁面是什麼都沒有的,應為還沒有守護程序

7.安裝jdk以及tomcat,守護程序
yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.82/bin/apache-tomcat-8.5.35.tar.gz
tar -xf apache-tomcat-8.5.35.tar.gz  -C /data/app
cd /data/app
ln -sv apache-tomcat-8.5.35.tar.gz/ tomcat

8.配置supervisord.conf檔案
mkdir /etc/supervisor/conf.d
cd conf.d
vi tomcat.ini

[program:tomcat]
 user=root
 command=/data/app/tomcat/bin/catalina.sh run;啟動tomcat
 autostart=true
 autorestart=true
 startsecs=5
 priority=1
 stopasgroup=true
 killasgroup=true
 stdout_logfile=/data/app/tomcat/logs/catalina.out

說明：
program:tomcat------->頁面展示名稱
command-------------->執行指令

修改檔案supervisord.conf,在檔案最下面
[include]
files = /etc/supervisor/config.d/*.ini

8.執行指令
supervisorctl update
這時候在重新整理頁面就會出現tomcat程序了

9.其他指令
supervisorctl status
supervisorctl stop tomcat #關閉tomcat程序
supervisorctl start tomcat #啟動tomcat程序 
supervisorctl restart tomcat #重新開機tomcat程序
supervisorctl reread
supervisorctl update

二、部署supervisor-monitor監控

準備工作:監控守護程序伺服器,例如：192.168.0.120

1.首先部署nginx
  安裝編譯工具及庫檔案
  yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

  首先要安裝 PCRE
  cd /usr/local/src/

  下載下傳pcre
  wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

  解壓pcre
  tar zxvf pcre-8.35.tar.gz

  編譯安裝
  cd pcre-8.35
  ./configure
  make && make install

2.下載下傳安裝nginx
  cd /usr/local/src/
  
  下載下傳nginx
  wget http://nginx.org/download/nginx-1.6.2.tar.gz
 
  解壓
  tar zxvf nginx-1.6.2.tar.gz

  編譯安裝
  cd nginx-1.6.2
  ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35

  make
  make install

3.修改nginx配置檔案
vi /usr/local/webserver/nginx/conf/nginx.conf

user www www;
 worker_processes 2; #設定值和CPU核心數一緻
 error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志級别
 pid /usr/local/webserver/nginx/nginx.pid;
 Specifies the value for maximum file descriptors that can be opened by this process.
 worker_rlimit_nofile 65535;
 events
 {
   use epoll;
   worker_connections 65535;
 }
 http
 {
   include mime.types;
   default_type application/octet-stream;
   log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
                '$status $body_bytes_sent "$http_referer" '
                '"$http_user_agent" $http_x_forwarded_for';
 charset gb2312;
 server_names_hash_bucket_size 128;
   client_header_buffer_size 32k;
   large_client_header_buffers 4 32k;
   client_max_body_size 8m;
 sendfile on;
   tcp_nopush on;
   keepalive_timeout 60;
   tcp_nodelay on;
   fastcgi_connect_timeout 300;
   fastcgi_send_timeout 300;
   fastcgi_read_timeout 300;
   fastcgi_buffer_size 64k;
   fastcgi_buffers 4 64k;
   fastcgi_busy_buffers_size 128k;
   fastcgi_temp_file_write_size 128k;
   gzip on; 
   gzip_min_length 1k;
   gzip_buffers 4 16k;
   gzip_http_version 1.0;
   gzip_comp_level 2;
   gzip_types text/plain application/x-javascript text/css application/xml;
   gzip_vary on;
 #limit_zone crawler $binary_remote_addr 10m;
  #下面是server虛拟主機的配置
  server
   {
     listen 80;#監聽端口
     server_name localhost;#域名
     index index.html index.htm index.php;
     root /usr/local/webserver/nginx/html;#站點目錄
       location ~ ..(php|php5)?$     {       #fastcgi_pass unix:/tmp/php-cgi.sock;       fastcgi_pass 127.0.0.1:9000;       fastcgi_index index.php;       include fastcgi.conf;     }     location ~ ..(gif|jpg|jpeg|png|bmp|swf|ico)$
     {
       expires 30d;
   # access_log off;
     }
     location ~ .*.(js|css)?$
     {
       expires 15d;
    # access_log off;
     }
     access_log off;
   }
 }

4.校驗并啟動nginx
/usr/local/webserver/nginx/sbin/nginx -t
/usr/local/webserver/nginx/sbin/nginx

5.通路nginx
http://ip

6.安裝php
yum -y install php-fpm
vi /etc/php-fpm.d/www.conf
user = root
group = root

7.啟動php
/usr/sbin/php-fpm -R &

8.檢視php是否啟動成功
netstat -antp

9.測試php
配置nginx
vi /usr/local/webserver/nginx/conf/nginx.conf
location ~ .php$ {
     fastcgi_pass   127.0.0.1:9000;
     fastcgi_index  index.php;
     fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
     fastcgi_param  SCHEME $scheme;
     include        fastcgi_params;
 }

10.在/usr/local/webserver/nginx/html下建立index.php檔案
vi /usr/local/webserver/nginx/html/index.php

<?php
phpinfo();
?>

11.重新整理nginx配置并通路頁面
/usr/local/webserver/nginx/sbin/nginx -s reload
http://ip

成功的話會出現php版本資訊

12.安裝supervisord-monitor
  下載下傳supervisord-monitor源碼
  git clone https://github.com/mlazarov/supervisord-monitor.git

  修改php檔案
  cd /usr/local/webserver/nginx/html/supervisord-monitor/application/config
  cp supervisor.php.example supervisor.php

  vi supervisor.php
  $config['supervisor_servers'] = array(
     'server01' => array(
         'url' => 'http://部署supervisor伺服器ip/RPC2',
         'port' => '9001',
         'username' => 'user(上面配置的supervisor)',
         'password' => '123'
     )
  );

13.配置nginx
  建立conf.d
  mkdir /usr/local/webserver/nginx/conf/conf.d
  
  建立配置檔案supervisor
  vi supervisor.conf
  
  server {
     listen       80 default_server;
     server_name  本機IP位址;
     root /usr/local/webserver/nginx/html/supervisord-monitor/public_html;
     location / {
         index index.php;
      }
     location /control/ {
         index  index.php;
         rewrite  /(.*)$  /index.php?$1  last;
     }
     location ~ .php$ {
         #try_files $uri =404;
         fastcgi_pass   127.0.0.1:9000;
         fastcgi_index  index.php;
         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
         fastcgi_param  SCHEME $scheme;
         include        fastcgi_params;
     }
   }

  将配置檔案引入nginx.conf
  vi /usr/local/webserver/nginx/conf/nginx.conf

  在server之前引入即可
  include /usr/local/webserver/nginx/conf/conf.d/*.conf;
  
14.校驗配置檔案并更新
  /usr/local/webserver/nginx/sbin/nginx -t
  /usr/local/webserver/nginx/sbin/nginx -s reload

15.通路supervisord-monitor監控
http://IP位址
出現下圖就是部署成功了

三、如果新怎的守護程序伺服器隻需要修改監控伺服器以下配置即可，其他操作都是一步驟

vi supervisor.php
   $config['supervisor_servers'] = array(
      'server01' => array(
          'url' => 'http://部署supervisor伺服器ip/RPC2',
          'port' => '9001',
          'username' => 'user(上面配置的supervisor)',
          'password' => '123'
      ),'server02' => array(
           'url' => 'http://部署supervisor伺服器ip/RPC2',
           'port' => '9001',
           'username' => 'user(上面配置的supervisor)',
           'password' => '123'
       )
   );
