4 安装Mysql

1) 安装

# su - root
 
# rpm -ivh mysql-community-common-8.3.0-1.el8.x86_64.rpm
# rpm -ivh mysql-community-client-plugins-8.3.0-1.el8.x86_64.rpm
# rpm -ivh mysql-community-libs-8.3.0-1.el8.x86_64.rpm
# rpm -ivh mysql-community-client-8.3.0-1.el8.x86_64.rpm
# rpm -ivh mysql-community-icu-data-files-8.3.0-1.el8.x86_64.rpm
# rpm -ivh mysql-community-server-8.3.0-1.el8.x86_64.rpm
 
如果安装mysql-community-server-8.3.0-1.el8.x86_64.rpm报错,mariadb包跟mysql冲突，需要卸载
error: Failed dependencies:
        mariadb-connector-c-config is obsoleted by mysql-community-server-8.3.0-1.el8.x86_64
 
 
# rpm -qa | grep mariadb
# yum remove -y mariadb-connector-c-config

2) 初始化

# mysqld --initialize 
# grep 'temporary password' /var/log/mysqld.log
A temporary password is generated for root@localhost: !Ib<2qzkr0.W    # !Ib<2qzkr0.W是初始密码
 
# systemctl start mysqld    # 启动mysql
 
# mysql -uroot -p    # 初次登陆mysql
输入初始密码
 
mysql> ALTER USER USER() IDENTIFIED BY '密码';    # 修改初始密码
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

5 开启远程连接

# mysql -uroot -p
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
 
mysql> use mysql
mysql> select user,host from user;
+------------------+-----------+
| user             | host      |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| root             | localhost |
+------------------+-----------+
 
mysql> update user set host="%" where user="root";    # 将root帐号的host设置为%
 
mysql> flush privileges;    # 使本次修改立即生效
 
# systemctl stop firewalld    # 关闭防火墙

如果是云服务器,需要在"控制台"放开对应端口
