方法一：

如果运行phpMyAdmin发现如下错误:

The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.
是因为没有mbstring扩展所致,解决方法如下

在SSH登录LINUX后执行以下命令:

1.执行
yum install php-mbstring

2. 修改php.ini (这一步非常重要, 部分lxadmin版本无法自动修改)
echo ‘extension=mbstring.so’ >>/etc/php.ini #更具php安装目录而定

3. 重启web service
如果是apache: service httpd restart

 

方法二：

php 5.36

安装目录：/usr/local/php

cd /usr/src/php-5.3.6/ext/mbstring

/usr/local/php/bin/phpize #create makefiles

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

echo ‘extension=mbstring.so’ >>/usr/local/php/php.ini

service httpd reload 

使用/usr/local/php/bin/php -v #查看配置是否错误

使用php.info查看mbstring是否安装成功

出现如下图则表明安装成功。
