在mysql安装过程中如下内容：
Installed:
mysql-community-client.x86_640:5.6.26-2.el7 mysql-community-devel.x86_640:5.6.26-2.el7
mysql-community-libs.x86_640:5.6.26-2.el7 mysql-community-server.x86_640:5.6.26-2.el7
Dependency Installed:
mysql-community-common.x86_640:5.6.26-2.el7
Replaced:
mariadb.x86_641:5.5.41-2.el7_0 mariadb-devel.x86_64 1:5.5.41-2.el7_0 mariadb-libs.x86_641:5.5.41-2.el7_0
mariadb-server.x86_64 1:5.5.41-2.el7_0
所以安装完以后mariadb自动就被替换了，将不再生效。
[root@yl-web yl]# rpm -qa |grep mariadb
[root@yl-web yl]#
配置mysql
1、编码
mysql配置文件为/etc/my.cnf
最后加上编码配置
[mysql]
default-character-set=utf8
这里的字符编码必须和/usr/share/mysql/charsets/Index.xml中一致。
2、远程连接设置
把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户。
mysql> grantall privileges on *.* to root@'%'identified by 'password';
如果是新用户而不是root，则要先新建用户
mysql>createuser 'username'@'%' identified by 'password';
此时就可以进行远程连接了。
