這篇文章介紹deployer工具.

它支持并行部署,版本回退,可以很方便的編寫(xiě)命令并設(shè)置執(zhí)行時(shí)機(jī),并且支持很多主流的php框架提供開(kāi)箱可用的一些方案.

使用deployer的情況下:
circleCI配置文件中的deployment模塊需要修改,其中dep -v deploy staging命令會(huì)執(zhí)行當(dāng)前目錄中的deploy.php文件

deployment:
  staging:
      branch: develop
      commands:
        -  curl -LO https://deployer.org/deployer.phar
        -  sudo mv deployer.phar /usr/local/bin/dep
        -  chmod +x /usr/local/bin/dep
        -  dep -v deploy test
        -  dep -v deploy staging
  production:
      branch: master
      commands:
        -  curl -LO https://deployer.org/deployer.phar
        -  sudo mv deployer.phar /usr/local/bin/dep
        -  chmod +x /usr/local/bin/dep
        -  dep -v deploy production

我使用的deployer的一個(gè)例子:

要說(shuō)明一下腳本中的幾個(gè)host,其實(shí)是有三組host,里面的stage分別是test/staging/production對(duì)應(yīng)不同的環(huán)境,這個(gè)不是這篇文章的重點(diǎn)所以不介紹.
并且host配置的這么奇怪是因?yàn)閔ost不能重名...所以我就各種辦法...

<?php
namespace Deployer;

require 'recipe/laravel.php';

use Symfony\Component\Console\Input\InputOption;


//dep -vv deploy --first true  --branch develop -- test


option('first', null, InputOption::VALUE_OPTIONAL, 'If first deploy.');

// Configuration

set('repository', 'git@github.com:never615/easy-admin.git');
set('allow_anonymous_stats', false);

// Hosts
host('server-1.xxx.com', 'server-2.xxx.com')
    ->stage('production')
    ->set("branch", "master")
    ->user("user")
    ->port("88888")
    ->set('deploy_path', '/app/xxx/easy_admin/production')
    ->forwardAgent(true)
    ->multiplexing(true)
    ->addSshOption('UserKnownHostsFile', '/dev/null')
    ->addSshOption('StrictHostKeyChecking', 'no');


host('119.23.111.111', '120.76.111.112')
    ->stage('staging')
    ->set("branch", "develop")
    ->user("user")
    ->port("88888")
    ->set('deploy_path', '/app/xxx/easy_admin/staging')
    ->forwardAgent(true)
    ->multiplexing(true)
    ->addSshOption('UserKnownHostsFile', '/dev/null')
    ->addSshOption('StrictHostKeyChecking', 'no');


host('test')
    ->hostname('119.23.111.111')
    ->stage('test')
    ->set("branch", "develop")
    ->user("user")
    ->port("88888")
    ->set('deploy_path', '/app/xxx/easy_admin/test')
    ->forwardAgent(true)
    ->addSshOption('UserKnownHostsFile', '/dev/null')
    ->addSshOption('StrictHostKeyChecking', 'no');


// Tasks
desc('first deploy');
task('deploy:first', function () {
    if (input()->hasOption('first')) {
        $first = input()->getOption('first');
        if ($first) {
            run('{{bin/php}} {{release_path}}/artisan tool:install');
            run('{{bin/php}} {{release_path}}/artisan admin:install');
            run('{{bin/php}} {{release_path}}/artisan user:install');
            run('{{bin/php}} {{release_path}}/artisan mall:install');
            run('{{bin/php}} {{release_path}}/artisan activity:install');
            //生成的key需要各個(gè)地方一樣
//            run('{{bin/php}} {{release_path}}/artisan passport:install');
//            run('{{bin/php}} {{release_path}}/artisan passport:keys');
            run('{{bin/php}} {{release_path}}/artisan passport:client --personal');
        }
    }
});

desc('update');
task('deploy:update',function(){
    run('yes|{{bin/php}} {{release_path}}/artisan tool:update');
    run('yes|{{bin/php}} {{release_path}}/artisan admin:update');
    run('yes|{{bin/php}} {{release_path}}/artisan user:update');
    run('yes|{{bin/php}} {{release_path}}/artisan mall:update');
    run('yes|{{bin/php}} {{release_path}}/artisan activity:update');
});



task('deploy:chown_chgrp',function(){
    run('sudo chown -R nginx {{release_path}}');
    run('sudo chgrp -R www {{release_path}}');
    run('sudo chmod -R 775 {{release_path}}');
});

desc('copy env');
task('deploy:cp_env', 'cp .env.{{stage}} .env');

desc('copy composer');
task('deploy:cp_composer', 'cp composer.json.circle composer.json');

desc('Restart PHP-FPM service');
task('php-fpm:restart', function () {
    // The user must have rights for restart service
    // /etc/sudoers: username ALL=NOPASSWD:/bin/systemctl restart php-fpm.service
    run('sudo systemctl restart php-fpm.service');
});

task("artisan:vendor", '
        php artisan queue:restart;
    ');

after('deploy:symlink', 'php-fpm:restart');
after('deploy:update_code', 'deploy:cp_env');
after('deploy:update_code', 'deploy:cp_composer');


// [Optional] if deploy fails automatically unlock.
after('deploy:failed', 'deploy:unlock');

// first deploy run
after('artisan:vendor', 'deploy:first');
// plugin install
after('artisan:vendor', 'deploy:update');

after('deploy:symlink', 'deploy:chown_chgrp');

// publish vendor
before('deploy:symlink', 'artisan:vendor');



// Migrate database before symlink new release.

before('deploy:symlink', 'artisan:migrate');

于是新的部署流程如下:

部署流程

1. 平時(shí)在開(kāi)發(fā)環(huán)境直接使用文件上傳的方式更新代碼
2. 每開(kāi)發(fā)完成一個(gè)功能,就提交代碼到開(kāi)發(fā)分支(github)
3. 提交到github后會(huì)觸發(fā)鉤子,CircleCI開(kāi)始執(zhí)行測(cè)試,然后使用deployer部署代碼到各服務(wù)器
4. 測(cè)試沒(méi)有問(wèn)題后,提交代碼到master分支,會(huì)自動(dòng)部署到各服務(wù)器的正式環(huán)境

整個(gè)部署流程,不需要人參與,就像平常一樣,開(kāi)發(fā)完一個(gè)功能提交到github而已.
