自制YUM仓库
简单写一写，用作仓库的虚拟机IP为192.168.149.129。我计划将/usr/local/src这个目录下的软件当做YUM源。首先确保http服务正常。
第一部分 搭建局域网yum源
1、我用的是apache，默认根目录是/var/www/html，所以在这个目录下做了一个软链接：
[root@bogon html]# ln -s /usr/local/src .
[root@bogon html]# ll
total 3
lrwxrwxrwx 1 root root 14 Nov 2 11:13 src -> /usr/local/src2、使用createrepo命令格式化仓库：
[root@bogon src]# createrepo .

3、将rpm包放在src目录下，更新一下，在客户端应该就能看到这个包了：
[root@bogon src]# createrepo --update .
Spawning worker 0 with 1 pkgs
Spawning worker 1 with 0 pkgs

[root@localhost yum.repos.d]# cat test.repo
[TestYum]
name=TestYum
baseurl=http://192.168.149.129/src
gpgcheck=0
enabled=15、运行yum clean all && yum repolist，嗯，确实有1个包，完成。
第二部分 同步外网yum源中的软件包
6、在内网环境下，只有1个软件包是不行的，需要同步外网的yum源。首先，查询可以同步的外网yum源。mysql-tools-community源只有95个软件包，就同步它的软件包了。

使用reposync命令下载该源的软件包：
# reposync -r mysql-tools-community -p /var/www/html/src7、使用createrepo更新本地yum仓库。为了测试需要，下载了21个包，之后中止了其余软件包的下载。
# createrepo /var/www/html/src
