redhat6.6+nginx安装phpmyadmin

phpmyadmin可以被理解成一个web程序，要放在nginx的www目录下解释执行，我的www目录是/var/www

配置好了虚拟主机，访问www.mathandcs.com/phpmyadmin时，报500错误。

1.查看nginx 错误日志：

tail -f /var/log/nginx/error.log 没发现什么问题，很困惑

2.然后看php-fpm的错误日志：

tail -f /var/log/php-fpm/www-error.log:

发现：PHP Fatal error:  Call to undefined function mb_detect_encoding() 

好了，发现了问题，解决问题就简单了，google之：

得到解决办法（地址：http://stackoverflow.com/questions/10278561/how-to-install-php-mbstring-on-centos-6-2）：

*Make sure you update your linux box first

yum update

In case someone still has this problem, this is a valid solution:

centos-release : rpm -q centos-release

Centos 6.*

wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm

Centos 5.*

wget http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
rpm -Uvh remi-release-5*.rpm

Then just do this to update:

yum --enablerepo=remi upgrade php-mbstring

Or this to install:

yum --enablerepo=remi install php-mbstring

安装了php-mbstring这个拓展就ok了。
