mysql安装常见的方法有四种
序号 | 安装方式 | 说明 |
1 | yum\rpm | 简单、快速，不能定制参数 |
2 | 二进制 | 解压，简单配置就可使用 免安装 mysql-a.b.c-linux2.x-x86_64.tar.gz |
3 | 源码编译 | 可以定制参数，安装时间长 mysql-a.b.c.tar.gz |
4 | 源码制成rpm包 | 把源码制作成符合要求的rpm,通过yum安装 |
MySQL RPM包下载
官网下载地址：
https://dev.mysql.com/downloads/mysql/
1. yum安装依赖包
yum -y install lrzsz wget perl-Digest-MD5
yum -y install numactl
yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make
添加用户及组
[root@jeames ~]# groupadd mysql
删除组:groupdel users
--用户加到组并指定根目录
[root@jeames ~]# useradd -g mysql -d /home/mysql mysql
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
删除用户:userdel mysql
[root@jeames ~]# passwd mysql
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
安装Mysql
[root@jeames ~]# md5sum mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar
edf4d0f95867f62cdcc97b7349bedc59 mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar
[root@jeames ~]# tar -xvf mysql-8.0.27-1.el8.x86_64.rpm-bundle.tar -C /home/mysql/
## 必须安装的四个RPM包
mysql-community-common-8.0.27-1.el8.x86_64.rpm
mysql-community-libs-8.0.27-1.el8.x86_64.rpm
mysql-community-client-8.0.27-1.el8.x86_64.rpm 是客户端的安装包
mysql-community-server-8.0.27-1.el8.x86_64.rpm 是服务端的安装包
## 授权
root@jeames ~]# chown -R mysql:mysql /home/mysql/
## 安装
注：root用户下操作
[root@jeames ~]# cd /home/mysql/
装顺序：包之间相互依赖，所以必须注意安装顺序
✓ 先装 common
✓ 再装 libs
✓ 再装 client
✓ 最后装 server
[root@jeames mysql]# rpm -ivh mysql-community-common-8.0.27-1.el8.x86_64.rpm
[root@jeames mysql]# rpm -ivh --force --nodeps mysql-community-libs-8.0.27-1.el8.x86_64.rpm
[root@jeames mysql]# rpm -ivh mysql-community-client-8.0.27-1.el8.x86_64.rpm --force --nodeps
[root@jeames mysql]# rpm -ivh mysql-community-server-8.0.27-1.el8.x86_64.rpm --f

安装 MySQL
## 用户及目录创建
注：可以部署多个实例，通过端口区分root 用户操作：
mkdir -p /mysql/data/mysql3306
mkdir -p /mysql/app/
mkdir -p /mysql/conf/
mkdir -p /mysql/data/mysql3306/pid/
mkdir -p /mysql/data/mysql3306/socket/
mkdir -p /mysql/data/mysql3306/log/
mkdir -p /mysql/data/mysql3306/binlog/
mkdir -p /mysql/data/mysql3306/errlog
mkdir -p /mysql/data/mysql3306/relaylog/
mkdir -p /mysql/data/mysql3306/slowlog/
mkdir -p /mysql/data/mysql3306/tmp/
## 用户及组
[root@rhel76 ~]# groupadd mysql
[root@rhel76 ~]# useradd -g mysql mysql
[root@rhel76 ~]# chown -R mysql:mysql /mysql
[root@rhel76 ~]# passwd mysql
Changing password for user mysql.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@rhel76 ~]# cat /etc/group | grep mysql
mysql:x:1001:
[root@rhel76 ~]# cat /etc/passwd | grep mysql
mysql:x:1001:1001::/home/mysql:/bin/bash
## 上传软件包并解压
[root@rhel76 ~]# cp mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz /mysql/app
[root@rhel76 ~]# chown -R mysql:mysql /mysql
mysql用户操作
[root@rhel76 ~]# su - mysql
md5 值验证，保证下载到的软件包无破损无木马
[mysql@rhel76 ~]$ cd /mysql/app
[mysql@rhel76 app]$ ll
total 1168588

0bdd171cb8464ba32f65f7bf58bc9533 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
解压软件包并重命名
[mysql@rhel76 app]$ tar xvf mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz
[mysql@rhel76 app]$ mv mysql-8.0.27-linux-glibc2.12-x86_64 mysql8.0.27
