一.下载链接
https://mirrors.aliyun.com/mysql/MySQL-8.0/mysql-8.0.28-linux-glibc2.12-x86_64.tar.xz
二.官方下载文档
MySQL :: MySQL 8.3 Reference Manual :: 2.2 Installing MySQL on Unix/Linux Using Generic Binaries
三.开始下载
3.1.获取软件包
bash
-rw-r--r-- 1 root root 1.2G 3月 7 11:20 mysql-8.0.28-linux-glibc2.12-x86_64.tar.xz3.2.安装
bash
因为yum方式下载过来做了下参照
[root@node1 ~]# groupadd -g 27 -r mysql
[root@node1 ~]# useradd -u 27 -g 27 -c 'MYSQL Server' -r -s /sbin/nologin mysql
[root@node1 ~]# tail -1 /etc/passwd
mysql:x:27:27:MYSQL Server:/home/mysql:/sbin/nologin#就是单纯参照安装文档一步不落的做一遍
bash
[root@node1 ~]# tar xf /root/mysql-8.0.28-linux-glibc2.12-x86_64.tar.xz -C /usr/local/
创建软连接（换名）
[root@node1 local]# ln -sv /usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/ /usr/local/mysql
'/usr/local/mysql' -> '/usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/'
bash
[root@node1 local]# cd mysql
[root@node1 mysql]# mkdir mysql-files
[root@node1 mysql]# chown mysql:mysql mysql-files
[root@node1 mysql]# chmod 750 mysql-files
bash
安装初始化，会产生密码
[root@node1 mysql]# bin/mysqld --initialize --user=mysql
2024-03-07T03:41:13.560187Z 0 [System] [MY-013169] [Server] /usr/local/mysql-8.0.28-linux-glibc2.12-x86_64/bin/mysqld (mysqld 8.0.28) initializing of server in progress as process 2019

bash
mysql服务开启ssl加密功能，安装和启用 ssl，不启用 ssl 可忽略这一步
[root@node1 mysql]# bin/mysql_ssl_rsa_setup
bash
[root@node1 mysql]# bin/mysqld_safe --user=mysql &3.3.配置环境变量
为了在在任何文件夹下都调用到某一指定目录下的文件，我们就应该配置环境变量(指定目录路径)，让系统在你所配置的路径下去自己查找这些文件然后运行，而不用我们去手动打开这些文件所在目录再运行
bash
[root@node1 mysql]# vi /etc/profile.d/mysql.sh
export PATH=$PATH:/usr/local/mysql/bin/
[root@node1 mysql]# source /etc/profile.d/mysql.sh3.4.启动，报错 ，解决，成功
bash
启动，报错
[root@node1 mysql]# mysql -uroot -p'8h.o8s<qNIM3'
mysql: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
解决：
[root@node1 mysql]# yum install ncurses-compat-libs
再启动：
[root@node1 mysql]# mysql -uroot -p'8h.o8s<qNIM3'

bash

[root@node1 mysql]# mysql -uroot -p'Mnwl_0816'

mysql> 3.6.提供服务脚本
bash
[root@node1 mysql]# mysqladmin -uroot -p'Mnwl_0816' shutdown
添加 mysql 服务到系统服务
[root@node1 mysql]# cp support-files/mysql.server /etc/init.d/mysql.server
[root@node1 mysql]# chkconfig --add mysqld
3.7.从yum安装的机子中拷一份配置文件
bash
[root@node1 mysql]# scp -r 192.168.32.132:/etc/my.cnf.d/ /etc/
[root@node1 mysql]# scp -r 192.168.32.132:/etc/my.cnf /etc/3.8.修改相关参数
root@node1 my.cnf.d# vim mysql-server.cnf
bash
basedir=/usr/local/mysql/
datadir=/usr/local/mysql/data/
socket=/tmp/mysql.sock
log-error=/usr/local/mysql/data/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid3.9.重启报错-已解决
原来是有进程在进行
