phpmyadmin提示The mbstring extension is missing
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
centos7 安装 mariadb 出现冲突

按照之前看到的文章：

系统本身自带 MariaDB，我们需要先删除掉系统本身带的，才能正常安装比较新的

然后再次进行安装，一切顺利
yum install mariadb101-server
然后启动
[root@localhost ~]# systemctl start mariadb
添加到开机启动中。
[root@localhost ~]# systemctl enable mariadb Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
Centos7 安装PHP7.0
默认centos7的源中php的版本是5.6的
秉着使用最新的版本的原则，此次想要安装PHP7.0
添加源：
rpm -Uvh https://centos7.iuscommunity.org/ius-release.rpm
[root@localhost ~]# rpm -Uvh https://centos7.iuscommunity.org/ius-release.rpm Retrieving https://centos7.iuscommunity.org/ius-release.rpm warning: /var/tmp/rpm-tmp.tOxBVX: Header V4 DSA/SHA1 Signature, key ID 9cd4953f: NOKEY Preparing... ################################# [100%] Updating / installing... 1:ius-release-1.0-14.ius.centos7 ################################# [100%]
然后搜索php7，可以看到下面的软件包，直选择想要的直接yum install
