centos7 装了nginx 和 mariadb 以及php71u-fpm后，我开始尝试使用phpmyadmin 去连接数据库。
出现如下错误：
网上着直接安装mbstring
http://www.jb51.net/article/58612.htm
yum install php-mbstring
于是搜索下:
[root@localhost www]# yum search php71u-mbstring Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * epel: mirror.premi.st * extras: mirrors.tuna.tsinghua.edu.cn * ius: mirrors.tuna.tsinghua.edu.cn * updates: mirrors.nwsuaf.edu.cn * webtatic: us-east.repo.webtatic.com ========================================================================= N/S matched: php71u-mbstring ========================================================================== php71u-mbstring.x86_64 : A module for PHP applications which need multi-byte string handling Name and summary matches only, use "search all" for everything. [root@localhost www]#
果然有这个包，直接安装
yum -y install php71u-mbstring
然后重启php-fpm
systemctl restart php-fpm
刷新页面，出现了新的错误
缺少json，直接yum search 然后安装
重启php-fpm
