Distribution of configuration files to different service nodes and centralized control of Web services for each node via Rex + module

1, all business testing machine different node run different business (through hosts view)

[[email protected] rex]# cat /etc/hosts127.0.0.1  mail.weike.com mx  localhost localhost.localdomain localhost4 localhost4.localdomain4::1          localhost localhost.localdomain localhost6  localhost6.localdomain6192.168.0.128    node1    caisen192.168.0.129     node2    mail192.168.0.45     node3     guanwang192.168.0.164    node4     shopwap192.168.0.193    node5    gerenwap192.168.0.196     node6    appwap192.168.0.224    node7     geren192.168.0.226    node8    chaoshi192.168.0.228     node9    quanguo192.168.0.215&nbSp;   node10    boss 

2, the different Web services are organized in the form of modules for centralized management, rexfile configuration information is as follows:

use rex -feature => [' 1.3 '];use strict;use warnings; #use  data::D umper;# Modular configuration for different service types require servers::quanguo;require servers::chaoshi;require servers::geren; Require servers::boss;require servers::shopwap;require servers::gerenwap;require servers:: appwap;require servers::guanwang; #远程连接登陆方式private_key   "/root/.ssh/id_rsa";p ublic_key  "/root/. Ssh/id_rsa.pub "; #设置线程数parallelism   ' Max '; #所有服务器节点group  all_servers        => "node[1..6]";group test_servers      => "node[1..2]"; desc  "Turn off Tomcat and WebLogic services on all nodes";task  "Stop_web",group=> "All_servers",sub{          #my   @ps =ps ();         #print   Dumper (@ps);         #my   @list =grep{$_->{"command"}==-5}ps (" Command "," ni ");         for my  $proc (PS ()) {                 if ($proc->{"command"}=~/java.*tomcat/is) {                          run  "./shutdown.sh",                                  cwd     => "/usr/local/tomcat/bin",                                  only_if => "Pgrep java";                          say  "Tomcat Service shutdown complete ";                         exit 0;                 }elsif ($proc->{"command"}=~/java.*?node1.*?weblogic/is) {                          run  "stop_node.sh",                                  only_if=> "Pgrep java";                         say   "WebLogic Service shutdown Complete";                         exit 0;                 }else{                         next;                 }         }        say  "Service has been closed";}; desc  "Start Tomcat and WebLogic services on all nodes";task  "Start_web",group=> "All_servers",sub{         if (Is_file ("/usr/local/tomcat/bin/startup.sh")) {                 run  "./startup.sh",                          cwd     => "/usr/loCal/tomcat/bin ",                         unless  => "Pgrep  java";         }else{                 run  "start_node.sh",                         unless   => "Pgrep java";        }         for my  $proc (PS ()) {                 if ($proc->{"command"}=~/java.*tomcat/i) {                          say  "Tomcat has started, process pID: ". $proc->{" pid "};                         exit 0;                 }elsif ($proc->{"command"}=~/java.*?node1.*? weblogic/is) {                         say  "WebLogic Service has started, process pid:". $proc->{"pid"};                          exit 0;                 }else{                         next;                 }        }         say  "Service failed to start";};

3, the configuration contents of each module are the same except for the distributed file name. The contents of the module are as follows

package servers::appwap;use rex -feature => [' 1.3 ';d esc  " Distribute the data source profile to the Personal hub WAP node server ";task " Deploy_gerenwap "," Appwap ",sub{         if (!is_dir ("/usr/local/dbsrc")) {                 file  "/USR/LOCAL/DBSRC",                         ensure  = > "Directory",                         owner   => "Root",                          group   => "Root",                         mode    =>755;                 upload  "/rex/conf/jdbc_moser.properties ","/USR/LOCAL/DBSRC ";        };         file  "/usr/local/dbsrc/jdbc_moser.properties",                 source=> "/rex/conf/jdbc_moser.properties",                 owner=> "Root",                 group=> " Root ",                 mode= >644,                on_ Change=> sub {                         say  "Data Source Configuration updated successfully";                 };}; 1;

4, you can view all the tasks you have defined by Rex-t:

[[email protected] rex]# rex-ttasks start_web start Tomcat and WebLogic services on all nodes Stop_web shut down Tomcat and WebLogic services on all nodes Servers:ap Pwap:deploy_gerenwap distributing the data source profile to the Personal hub WAP node server Servers:Boss:deploy_boss distributing the data source profile to the Boss node server Servers:Chaoshi:deploy_ Chaoshi Distributing data source profiles to supermarket node servers Servers:Geren:deploy_geren distributing data source profiles to personal Hub server Servers:Gerenwap:deploy_gerenwap distributing data source profiles To the personal hub WAP node Server Servers:Guanwang:deploy_guanwang distribute the data source profile to the official website node Server Servers:Quanguo:deploy_quanguo Distribute the data source profile to the National node server Servers:Shopwap:deploy_shopwap Distributing data source profiles to Marketplace WAP node server Groups all_servers node[1..10] test_servers node[1..2]

5, running related tasks only requires Rex + task to say Yes (e.g. Rex Start_web will start the Web service on all nodes) For example, I distribute different configuration files to the appropriate Web nodes I write all the class modules in a shell script as follows

[email protected] rex]# cat deploy_dbsr.sh #!/bin/bashrex Servers:Appwap:deploy_gerenwap Servers:Boss:deploy_boss Servers:Chaoshi:deploy_chaoshi Servers:Geren:deploy_geren Servers:Guanwang:deploy_guanwang Servers:gerenwap: Deploy_gerenwap Servers:Quanguo:deploy_quanguo Servers:Shopwap:deploy_shopwap

And then I'm going to run this script again.

If any one of the connection operation fails, it will print out the relevant information, according to the information can troubleshoot the cause of the error!
