ln -s /usr/local/php/bin/php /usr/local/bin/php

# 查看php.ini位置
php -i | grep php.ini

安装composer

curl -sS https://getcomposer.org/installer | php
mv composer.phar  /usr/local/bin/composer
composer config -g repo.packagist composer https://packagist.phpcomposer.com

安装deployer （我们安装的是最新的版本7.x，部分函数与6.x不一样）

mkdir /root/dep && cd dep
#第一种：通过 Phar 存档，只需运行一下命令即可
curl -LO https://deployer.org/deployer.phar
mv deployer.phar /usr/local/bin/dep
#第二种：通过 composer 安装
chmod +x /usr/local/bin/dep
composer require --dev deployer/deployer
#将别名添加到.bashrc文件中
alias dep='/root/dep/vendor/bin/dep'
source .bash_profile
#第三种：通过 Github 源代码安装：clone 最新的代码
1. git clone https://github.com/deployphp/deployer.git  
2. 在源代码目录下运行：
php ./build

?开始使用deployer

?dep init

?我们选择0，1是以配置的形式，我没有使用过(配置完成后用Import 导入即可)自己可以实验一下

这里有各种框架使用的模板，只需要在deployer.php 引用即可。不过使用的时候要注意跟自己的业务逻辑有没有冲突，尤其是清除缓存，有些redis 缓存不能删除，所以我本人一般不使用模板（直接选择2 common），另外很多框架和php系统也没有，私人定制似乎更好一些，在这里需要注意一点，必须设置php全局变量，因为deployer 默认命令是在/usr/lcoal/bin/php中 (现在以thinkphp 为例子)

<?php

namespace Deployer;
require 'recipe/common.php';
use Deployer\Exception\GracefulShutdownException;
add('recipes', ['thinkphp']);
set('writable_dirs', [
    'runtime',
]);
set('thinkphp_version', function () {
    $result = run('{{bin/php}} {{release_or_current_path}}/think --version');
    preg_match_all('/(\d+\.?)+/', $result, $matches);
    return $matches[0][0] ?? 6.0;
});

?接下来我们将详细讲解一下各个命令的作用

set(string $name, $value): void?设置配置选项

task(string $name, $body = null): Task?定义新任务并保存到任务列表

add(string $name, array $array): void??将新的配置参数合并到现有的配置数组。

run(string $command, ?array $options = [], ?int $timeout = null, ?int $idle_timeout = null, ?string $secret = null, ?array $env = null, ?bool $real_time_output = false, ?bool $no_throw = false): string??在远程主机上执行给定的命令

这几个命令比较常用，自己随便练习一下就能很快知道使用规则更多命令

脚本最主要的是配置公钥和私钥，主要是ssh远程登陆，和github（我们这里以gitee作为说明）

1.ssh登陆的公钥和私钥，在本地生成（也就是php客户端，不是服务器）我本地用的是虚拟机（linux）环境，因为我在windows 环境下使用deployer无法连接ssh，如果你能连接请告诉我。

ssh-keygen 输入文件名称，然后一路回车，如果你不输入名称，gitee生成公钥和私钥就会覆盖ssh的公钥私钥。因为默认名称都是id_rsa。生成文件的位置是在当前用户.ssh目录下（/root/.ssh）

?把公钥id_rsa.pub 复制到服务器/root/.ssh下的authorized_keys 多个公钥只需要在后面追加即可

编辑config 文件配置ssh信息，我的是

hostA 即是ssh 配置信息，host gitee.com 是gitee的配置

同理配置gitee ，然后把laravel-admin.pub 复制到gitee.com ssh keys中

常见的部署命令

#清理旧的发布版本 （只保留最近两个）
dep deploy:cleanup
#覆盖回滚候选 如果没有-o 选项直接回滚到上一个版本 (回滚后会生成一个新版本)
dep rollback -o rollback_candidate=123
#删除文件锁
dep deploy:unlock
#发布 host是要发布的环境，也即是config文件对应的
dep deploy hostA 

#如果要查看发布日志dep deploy hostA -vvv
