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...

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

平时在开发环境直接使用文件上传的方式更新代码

每开发完成一个功能,就提交代码到开发分支(github)

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

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.
