# 制作yum源

## 目标

* 主机M1：安装 httpd + createrepo
* 主机M2：使用M1的yum源

## 步骤

### 一、安装httpd

1、安装httpd

```
$ yum -y install httpd
```

2、配置httpd

2.1 修改httpd的数据根目录与绑定端口（可选）

httpd的数据根目录默认为`/var/www/html/`，默认监听`127.0.0.1:80`。如果需要修改，在配置文件 `/etc/httpd/conf/httpd.conf` 中修改如下两行

```
DocumentRoot "/home/pshizh/apps/httpd/DocumentRoot"
Listen 132.122.239.2:8050
```

备注：如果目录`/home/pshizh/apps/httpd/DocumentRoot`不存在，则须创建，否则会启动失败

2.2 为数据根目录添加访问权限规则

（如果使用默认路径`/var/www/html/`，则此步可省略，如果使用新的目录作为数据根目录，则添加如下内容） 在配置文件 `/etc/httpd/conf/httpd.conf` 中添加如下内容

```
<Directory "/home/pshizh/apps/httpd/DocumentRoot">
    Options Indexes FollowSymlinks
    AllowOverride None
    Require all granted
</Directory>
```

3、启动并验证

```
$ setenforce 0 
$ systemctl start httpd
```

此时，可以访问 132.122.239.2:8050验证启动是否成功

### 二、安装createrepo

4、安装createrepo

```
$ yum -y install createrepo
```

5、创建yum源的根目录

创建文件夹 `/home/pshizh/apps/httpd/DocumentRoot/centos`作为yum源的根目录

6、在`centos`目录下创建目录`packages`，并把rpm包拷贝到`packages`目录下

7、创建yum源

```
$ createrepo -d /home/pshizh/apps/httpd/DocumentRoot/centos
```

该步骤完成后，在centos目录下会出现一个repodata目录，里面保存了yum源的数据

8、访问132.122.239.2:8050/centos

8.1、更新yum源

如果packages中新增了rpm包，执行下列命令更新yum源

```
$ createrepo --update /home/pshizh/apps/httpd/DocumentRoot/centos
```

### 三、使用yum源（M2上）

9、在`/etc/yum.repo.d/`下创建 `qiiaojing.repo`文件，内容如下

```
[qiaojing]
name=qiaojing
baseurl=http://132.122.239.2:8050/centos
enabled=1
gpgcheck=0
```

10、更新cache

```
$ yum clean all & yum makecache
```

11、查看M1中可安装的软件

```
$ yum list | grep qiaojing
```

## 常见问题

1、`Permission denied: AH00072: make_sock: could not bind to address`

解决方法：`setenforce 0`

2、访问 132.122.239.2:8050/centos 时出现 403 forbidden

解决方法：按照2.2配置数据根目录的权限
