代码部署(三):使用部署工具deployer并配合github+circle进行部署

这篇文章介绍deployer工具.

它支持并行部署,版本回退,可以很方便的编写命令并设置执行时机,并且支持很多主流的php框架提供开箱可用的一些方案.

使用deployer的情况下:
circleCI配置文件中的deployment模块需要修改,其中dep -v deploy staging命令会执行当前目录中的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的一个例子:

要说明一下脚本中的几个host,其实是有三组host,里面的stage分别是test/staging/production对应不同的环境,这个不是这篇文章的重点所以不介绍.
并且host配置的这么奇怪是因为host不能重名...所以我就各种办法...

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需要各个地方一样
//            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. 平时在开发环境直接使用文件上传的方式更新代码
2. 每开发完成一个功能,就提交代码到开发分支(github)
3. 提交到github后会触发钩子,CircleCI开始执行测试,然后使用deployer部署代码到各服务器
4. 测试没有问题后,提交代码到master分支,会自动部署到各服务器的正式环境

整个部署流程,不需要人参与,就像平常一样,开发完一个功能提交到github而已.
