一、软件安装

1. 下载

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.33-1.el7.x86_64.rpm-bundle.tar

https://dev.mysql.com/downloads/mysql/
在这里插入图片描述

2. 解压

tar -xvf mysql-5.7.33-1.el7.x86_64.rpm-bundle.tar

解压后的列表：

 mysql-5.7.33-1.el7.x86_64.rpm-bundle.tarmysql-community-client-5.7.33-1.el7.x86_64.rpmmysql-community-common-5.7.33-1.el7.x86_64.rpmmysql-community-devel-5.7.33-1.el7.x86_64.rpmmysql-community-embedded-5.7.33-1.el7.x86_64.rpmmysql-community-embedded-compat-5.7.33-1.el7.x86_64.rpmmysql-community-embedded-devel-5.7.33-1.el7.x86_64.rpmmysql-community-libs-5.7.33-1.el7.x86_64.rpmmysql-community-libs-compat-5.7.33-1.el7.x86_64.rpmmysql-community-server-5.7.33-1.el7.x86_64.rpmmysql-community-test-5.7.33-1.el7.x86_64.rpm

3.安装

安装优先级：

rpm -ivh mysql-community-common-5.7.33-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.33-1.el7.x86_64.rpm
rpm -ivh  mysql-community-client-5.7.33-1.el7.x86_64.rpm
rpm -ivh  mysql-community-server-5.7.33-1.el7.x86_64.rpm

4. 跳过权限

# 配置mysql
vim /etc/my.cnf# 在[mysqld]标签下面添加，跳过校验
skip-grant-tables

5. 启动mysql服务端

# 启动mysql服务端
systemctl start mysqld.service# 使用客户端连接server端
mysql，按回车

6. 设置密码

# 设置密码
update mysql.user set authentication_string=password('123456') where user='root';# 刷新权限
flush privileges;

7. 允许远程连接

# 允许远程连接
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

8.开发3306端口

# 开放端口（开放后需要要重启防火墙才生效）
firewall-cmd --zone=public --add-port=8080/tcp --permanent
# 重新启动防火墙	
firewall-cmd --reload

二、安装报错方案

没遇到则可以跳过，

安装报错：
[root@bogon app]# rpm -ivh mysql-community-libs-5.7.33-1.el7.x86_64.rpm
警告：mysql-community-libs-5.7.33-1.el7.x86_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY
错误：依赖检测失败：mysql-community-common(x86-64) >= 5.7.9 被 mysql-community-libs-5.7.33-1.el7.x86_64 需要mariadb-libs 被 mysql-community-libs-5.7.33-1.el7.x86_64 取代
[root@bogon app]# ----------------------------------------------------------------
原因是 centos7  默认安装mariadb-libs包，需要卸载# 查看mariadb
[root@bogon app]# rpm -qa |grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64# 卸载mariadb
rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64# 跳过签名校验安装mysql(如果遇到签名错误，执行这条命令)
rpm -ivh --force --nodeps mysql-community-libs-5.7.33-1.el7.x86_64.rpm
