Linux 系统centOS6.7安装mysqlhotcopy遇到的各种问题记录

关于mysqlhotcopy安装在网上找了很多参考，总结安装mysqlhotcopy前需先安装perl-DBI 和 perl-DBD-MySQL，否则在运行mysqlhotcopy时会报错

[root@hadoop02 temp]# mysqlhotcopy fluxdb /home/01/temp/ccc
Can't locate DBI.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/bin/mysqlhotcopy line 25.

[root@hadoop02 temp]# cd /usr/local/lib64/perl5

[root@hadoop02 temp]# cd /usr/local/lib64
[root@hadoop02 lib64]# ls
[root@hadoop02 lib64]# ls
--说明perl没有安装

安装方法：

[root@localhost ~]# yum install perl-DBD* -y

但是当我执行上面这一步的时候却提示：No package perl-DBD* available.

[root@hadoop02 software]# yum install perl-DBD* -y
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
No package perl-DBD* available.
Error: Nothing to do

（what are you 弄啥呢？
难道是我的资料找的不对？
翻来覆去差不多都是这样下载安装的应该没问题

麻蛋我又去问百大爷No package perl-DBD* available.
居然奇迹的发现有铁！于是我按帖子内容操作了如下一番：）
No package perl-DBD available.解决办法：*
我的Linux版本是Linux version 2.6.32-573.el6.x86_64
依次执行下面命令解决
cd /home

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

rpm -ivh epel-release-6-8.noarch.rpm

再次执行yum install命令

[root@hadoop02 software]# yum install perl-DBD* -y
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

（卧槽，这次报错居然不一样了 ，说我路径不对
再次陷入懵逼中（请恕我菜），继续找百大爷，咋感觉百大爷比我亲爹还亲-.-！
功夫不负有心人！有铁！）
yum安装时出现：Cannot retrieve metalink for repository: epel. Please verify its path and try again
（心里再次默念：感谢大佬这种共享精神，才能让我这种小白苟延残喘）
解决方法： 一句话：把/etc/yum.repos.d/epel.repo，文件第3行注释去掉，把第四行注释掉。具体如下：

打开/etc/yum.repos.d/epel.repo，将

1.[epel]
2.name=Extra Packages for Enterprise Linux 6 - $basearch
3.#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4.mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

修改为

1.[epel]
2.name=Extra Packages for Enterprise Linux 6 - $basearch
3.baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4.#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

再清理源，重新安装

yum clean all
yum install -y 需要的包

（走到这心里默默的祈祷，别再出岔子了，哥快秃顶了！）

再次执行 yum install

 You could try using --skip-broken to work around the problem
** Found 3 pre-existing rpmdb problem(s), 'yum check' output follows:
2:postfix-2.6.6-6.el6_5.x86_64 has missing requires of libmysqlclient.so.16()(64bit)

2:postfix-2.6.6-6.el6_5.x86_64 has missing requires of mysql-libs

(我已经无力再为自己的无知吐槽了。。。继续百度)
yum报错： You could try using --skip-broken to work around the problem
解决办法：

一般都是用

yum install *** --skip-broken
后来在网上找到了解决方案:

1、将/etc/yum.repos.d文件夹下所有repos文件转移，然后把用的那个repo拷贝回来(保证repo所在目录只有你的那1个文件) 2、yum clean all

3、再yum install安装看看

我采用了yum install *** --skip-broken方法跳过了重复的包

安装到这先看看能不能用吧，希望这一天不要白瞎忙活
（瞎白忙活了后面补上太晚了，我特么明天还能活着起来吗-.-！）
