CentOS(tlinux)安装php55w失败，Requires: libjpeg.so.62(LIBJPEG_6.2)(64bit)解决办法
问题描述：
使用yum install 下载php55w（或php55w-gd 、php55w-bcmath等等）命令时，报了如下错误：
Error: Package: php55w-gd-5.5.34-1.w6.x86_64 (local)
Requires: libjpeg.so.62(LIBJPEG_6.2)(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
但实际上在/usr/lib以及/usr/lib64中都有这个libjpeg.so.62。
我的环境：TencentLinux1.2 （基于CentOS6.2）
解决办法：
既然自带的不起作用，那我就自己下一个吧，然后把原来的卸载了。
我用的是下面这个下载链接
wget http://mirror.ox.ac.uk/sites/mirror.centos.org/6/os/x86_64/Packages/libjpeg-turbo-1.2.1-3.el6_5.x86_64.rpm
当然你能找得到资源也可以不用这个。
下载好后rpm安装报错：

这是由于系统中已经存在了libjpeg：
卸载：
再执行yum install libjpeg-turbo-1.2.1-3.el6_5.x86_64.rpm。
最后再尝试安装php55w的东西，成功：
