CentOS 7安装 mysql-8.0.27-1.el7.x86_64.rpm 安装包

访问地址：

https://mirrors.aliyun.com/mysql/MySQL-8.0/?spm=a2c6h.25603864.0.0.17ec2ca8dkeWtv

CentOS 7 专用的 MySQL 8.0 安装包就是下面这个：

mysql-8.0.27-1.el7.x86_64.rpm-bundle.tar

✅ 下载 & 安装步骤

1. 下载这个包（两种方式）

• 方式 1：浏览器直接下点这个文件下载，保存到电脑，再上传到你的 CentOS 7 服务器上。

• 方式 2：服务器上用 wget 直接下

  wget https://mirrors.aliyun.com/mysql/MySQL-8.0/mysql-8.0.27-1.el7.x86_64.rpm-bundle.tar

2. 解压安装包

# 解压 tar 包
tar -xvf mysql-8.0.27-1.el7.x86_64.rpm-bundle.tar

# 解压后会生成一堆 .rpm 文件，我们只需要安装核心的几个：
# mysql-community-common-*.rpm
# mysql-community-libs-*.rpm
# mysql-community-client-*.rpm
# mysql-community-server-*.rpm

3. 按顺序安装（解决依赖）

# 先卸载系统自带的 mariadb-libs，避免冲突
yum remove -y mariadb-libs

# 安装依赖包
rpm -ivh mysql-community-common-8.0.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.27-1.el7.x86_64.rpm



#------------------------------------------
# 或者使用下面安装

rpm -ivh mysql-community-*.rpm --nodeps --force

4. 启动 & 初始化 MySQL

# 启动服务
systemctl start mysqld
# 开机自启
systemctl enable mysqld

# 查看初始临时密码
grep 'temporary password' /var/log/mysqld.log

# 登录并修改密码
mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY '你的强密码';

---

卸载现在装坏的 MySQL（必须做）

rpm -e --nodeps mysql-community-server
rpm -e --nodeps mysql-community-client
rpm -e --nodeps mysql-community-libs
rpm -e --nodeps mysql-community-common
rpm -e --nodeps mysql-community-client-plugins

启动报错

Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

看启动失败的具体原因

先执行下面的命令，看看到底是什么问题：

# 查看服务状态
systemctl status mysqld.service

# 查看详细日志
journalctl -xe | grep mysqld

journalctl -xe | grep mysqld
