Linux环境下搭建composer私服及内存限制的问题

在安装私服之前，我们需要先熟悉一下composer。安装

composer

Composer 是一个用于管理 PHP 项目中依赖关系的工具。这样您就可以声明您的项目所依赖的代码库，然后在项目目录（默认的vendor目录）中安装关联的依赖包。下载地址https://getcomposer.org/download/

# download 这里是下载 1.10.26 版本
# 当然你可以修改版本号，现在想要的版本
wget https://getcomposer.org/download/1.10.26/composer.phar

# rename
mv composer.phar /usr/local/bin/composer1.10.26
ln -s /usr/local/bin/composer1.10.26 /usr/local/bin/composer

# verify
# 这里需要注意，服务器上要安装有 PHP 程序，且有 php 命令才行
# 有时候安装PHP时候，会生成 类似 php-5.6 这样的命令， 没有默认的php命令
# 那么 做个软连接即可
# ln -s /bin/php5.6 /bin/php
/usr/local/bin/composer --version
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Composer version 1.10.26 2022-04-13 16:39:56

常见用途有：

• •composer init初始化composer.json install
• •composer install安装相关依赖到composer.json•composer update为强更新，忽略锁文件composer.lock，更新composer.json中的依赖，然后创建新的锁文件
• •composer自我更新版本号更新composer自己的版本
• •构建composer-项目依赖包版本/依赖包路径，例如composer作曲家项目源/项目目标目录1.0
• •composer配置主要用于设置存储库等composer相关的源地址。 composer 配置 -g secure -http false
  composer 配置 -g repo.my_repocomposer https://mirrors.aliyun.com/composer/
• • 请求composer帮助 command-name 指定命令，非常有用

composer搭建私服

这里介绍Satis

1的安装和部署。创建一个项目

2。配置 satis.json

{
    "name": "demo/repository",
    "homepage": "http://www.colinspace.com",
    "repositories": [
        {"type": "git", "url": "ssh://git@gitlab.xxxx.com:22/module/staff.git"}
    ],
    "require-all": true,
    "require-dependencies": true,
    "require-dev-dependencies": true
}

3。施工

[php@test-liuchao-01-vm /data/project/temp/satis Mon Apr 17 17:26:07]$ php bin/satis build satis.json dist
Scanning packages
wrote packages to dist/include/all$83d09112b76234b329306152ed4f1f88a9f98baf.json
Writing packages.json
Pruning include directories
Writing web view

4。配置NGINX

在配置NGINX之前，请确保在各自的主机上安装了PHP和php-fpm，然后运行php-fpm

server {
        include local_port.conf;
        server_name composer.xxx.com ;

        location / {
                proxy_redirect off;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_pass http://192.168.3.17:80;

        }

        access_log     /data/logs/nginx/access/curr/composer.xxxx.com.log;
        error_log      /data/logs/nginx/nginx_error_composer.xxxx.com.log;
}

。然后您就可以访问并使用号码 image-209678145171633 http://composer.xxx.com 5，在PHP项目的更新目录下设置并使用composer.json文件

{
    "name": "project-name",
    ... ...
    "repositories": [{
        "type": "composer",
        "url": "http://composer.kongfz.com"
      }],
      ....
}

然后在项目发布过程中出现了问题

内部composer的最后一个私有源，但项目开发过程中除了私有项目依赖之外，不可避免地会产生对公共第三方来源的依赖

因此，为了规范和方便管理，管理、运维人员按照主办方发布的内容进行操作在用户的主目录中。设置如下

[xxx]$ ls  -l ~/.composer/config.json
-rw-rw-r-- 1 jenkins jenkins 253 Apr 17 15:03 /var/lib/jenkins/.composer/config.json
[xxx]$ cat ~/.composer/config.json
{
    "config": {
        "secure-http": false
    },
    "repositories": [
        {
            "packagist": false
        },
        {
            "type": "composer",
            "url": "https://mirrors.cloud.tencent.com/composer/"
        }
    ]
}

然后配置项目的私有composer源。

但是我遇到了一个问题：

1。开发者没有在PC个人用户主目录本地配置公共composer配置，与上面

2中Jenkins主目录中的配置类似，开发者直接从第三个配置 - 参与公共和私人资源

3，然后在发布过程中运行项目作曲家安装。报错如下

Updating dependencies (including require-dev)
PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 32 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 32 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

从错误信息来看和内存有关系，但是执行时同步监控服务器内存就足够了。

然后进行调试验证，两种解决方案

1。安装composer后，命令改为 php -d memory_limit=-1 /usr/local/bin/composer install

memory_limit 为 - 1 表示不限制内存使用

2。删除开发者在composer.json文件中添加的第三方公共源码配置。公共资源仅存储在运维时配置的服务器对应的用户主目录中。运行安装没有问题。

所以对比一下上面两种解决方案：我认为主要问题不是内存限制，而是对第三方来源的反复依赖。
但是，如果项目配置中配置了源（无论是第三方还是私有），是否应该首先使用该源，并且无需查找本地配置的默认源？

所以最终的根本问题并没有在这里找到。如果有人知道原因请赐教

附录

1。 Composer 更新或版本 1 和版本 2 共存

版本 2 安装很快

# download
wget https://raw.githubusercontent.com/composer/getcomposer.org/76a7060ccb93902cd7576b67264ad91c8a2700e2/web/installer -O - -q | php -- --quiet

# rename
mv composer.phar /usr/local/bin/composer2

我在本文开头刚刚安装了 Composer 版本 1，如果你想让这个版本成为默认版本

，只需设置软连接。

ln -s /usr/local/bin/composer1.10.26 /usr/local/bin/composer1
# 默认1版本 
ln -s /usr/local/bin/composer1 /usr/local/bin/composer

或仅使用

/usr/local/bin/composer1 --version

/usr/local/bin/composer2 --version
