安装mysql

下载mysql源安装包

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
复制代码

安装mysql源

yum localinstall mysql57-community-release-el7-8.noarch.rpm
复制代码

检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*-community.*"
复制代码

安装mysql

yum install mysql-community-server
复制代码

启动MySQL服务

systemctl start mysqld
复制代码

开机启动

systemctl enable mysqld
systemctl daemon-reload
复制代码

修改root默认密码

grep 'temporary password' /var/log/mysqld.log
查看root密码而后登录
set global validate_password_policy=1;//0,1,2(密码长度)
SET PASSWORD = PASSWORD('root');
另外一种修改密码方法:
    use mysql;
    update user set authentication_string = password("root") where User = 'root';
复制代码

容许root远程登陆

//update user set host = ’%’ where user = ’root’;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;//password为本身设置密码。
flush privileges;
复制代码

改字符编码机

//停数据库
systemctl stop mysqld
//进入 my.cnf 文件，通常是在etc路径下
vim /etc/my.cnf
//加入要修改的字符集 修改完:wq退出
在[mysqld]下追加：
character-set-server=utf8
在[mysql]下追加：
default-character-set=utf8
//重启数据库
systemctl start mysqld
