一、官网下载安装MysqL-server
在命令行下输入：
# wget http://dev.MysqL.com/get/MysqL-community-release-el7-5.noarch.rpm
# rpm -ivh MysqL-community-release-el7-5.noarch.rpm
# yum install MysqL-community-server
安装成功后重启MysqL服务。
# service MysqLd restart
初次安装MysqL，root账户没有密码。
[root@yl-web yl]# MysqL -u root

不需要重启数据库即可生效。
在MysqL安装过程中如下内容：
Installed:
MysqL-community-client.x86_64 0:5.6.26-2.el7 MysqL-community-devel.x86_64 0:5.6.26-2.el7
MysqL-community-libs.x86_64 0:5.6.26-2.el7 MysqL-community-server.x86_64 0:5.6.26-2.el7
Dependency Installed:
MysqL-community-common.x86_64 0:5.6.26-2.el7
Replaced:
mariadb.x86_64 1:5.5.41-2.el7_0 mariadb-devel.x86_64 1:5.5.41-2.el7_0 mariadb-libs.x86_64 1:5.5.41-2.el7_0
mariadb-server.x86_64 1:5.5.41-2.el7_0
2、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> grant all 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>create user 'username'@'%' identified by 'password';
此时就可以进行远程连接了。
