官方文档操作步骤
# Preconfiguration setup
$> groupadd mysql
$> useradd -r -g mysql -s /bin/false mysql
# Beginning of source-build specific instructions
$> tar zxvf mysql-VERSION.tar.gz
$> cd mysql-VERSION
# Postinstallation setup
$> cd /usr/local/mysql
$> mkdir mysql-files
$> chown mysql:mysql mysql-files
$> chmod 750 mysql-files
$> bin/mysqld --initialize --user=mysql
$> bin/mysql_ssl_rsa_setup
$> bin/mysqld_safe --user=mysql &
# Next command is optional
$> cp support-files/mysql.server /etc/init.d/mysql.server

环境准备

[root@node01 ~]# yum remove mariadb
[root@node01 ~]# yum install libaio-devel -y
[root@node01 ~]# rm -rf /etc/my.cnf

创建用户组和用户

[root@node01 ~]# id mysql
id: mysql: no such user

[root@node01 ~]# groupadd -g 54321 mysql

[root@node01 ~]# useradd -r -g mysql -s /bin/false -u 54321 mysql
[root@node01 ~]# id mysql
uid=54321(mysql) gid=54321(mysql) groups=54321(mysql)

下载、解压缩、创建软链接

1、wget下载mysql

[root@node01 ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-8.0.33-linux-glibc2.12-x86_64.tar

2、解压缩

[root@node01 ~]# tar -xf mysql-8.0.33-linux-glibc2.12-x86_64.tar 
[root@node01 ~]# tar -xf mysql-8.0.33-linux-glibc2.12-x86_64.tar.xz -C /usr/local/cluster/


3、创建软链接
[root@node01 ~]# ln -s /usr/local/cluster/mysql-8.0.33-linux-glibc2.12-x86_64/ /usr/local/mysql


[root@node03 ~]# ll -h /usr/local/mysql/

drwxr-xr-x  2 7161 31415   77 Mar 17 03:33 support-files

创建数据目录

[root@node01 ~]# mkdir -p /data/mysql/3306/data
[root@node01 ~]# chown -R mysql:mysql /data/mysql/3306/data

参数配置

[root@node01 ~]# vim /etc/my.cnf

[client]

socket=/data/mysql/3306/data/mysql.sock
[mysql]
prompt="\\u@\\h [\\d]> "


[mysqld]
basedir=/usr/local/mysql
datadir=/data/mysql/3306/data
user=mysql
port=3306
pid-file=/data/mysql/3306/data/mysql.pid
socket=/data/mysql/3306/data/mysql.sock
log-error=/data/mysql/3306/data/mysql.err
log-timestamps=system

mysqlx_port=33060
mysqlx_socket=/data/mysql/3306/data/mysqlx.sock

初始化数据库

默认使用/etc/my.cnf参数文件
[root@node01 ~]# /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --initialize


看到日志输出显示临时密码说明初始化成功
[root@node01 ~]# more /data/mysql/3306/data/mysql.err | grep temporary
2023-07-28T14:32:43.094407+08:00 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: d&e:Vf=ss4D<

启动数据库

[root@node01 ~]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
[1] 77851
[root@node01 ~]# 2023-07-28T06:33:14.981353Z mysqld_safe Logging to '/data/mysql/3306/data/mysql.err'.

[root@node01 ~]# ps -ef |grep mysql | grep -v grep

配置环境变量

[root@node01 ~]# vim .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export JAVA_HOME=/usr/local/cluster/jdk
export PATH=$PATH:$JAVA_HOME/bin
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

[root@node01 ~]# source .bash_profile

登录测试

登录成功
[root@node01 ~]# mysql -uroot -p -S /data/mysql/3306/data/mysql.sock

使用配置文件启动

修改配置文件/usr/local/mysql/support-files/mysql.server

通过查看配置文件/usr/local/mysql/support-files/mysql.server
basedir默认/usr/local/mysql
datadir默认/usr/local/mysql/data，修改为/data/mysql/3306/data
配置文件默认是/etc/my.cnf，不需要修改


经过测试datadir不需要修改，因为配置文件默认是/etc/my.cnf，参数中指定了datadir的具体值

[root@node01 ~]# vim /usr/local/mysql/support-files/mysql.server


basedir=/usr/local/mysql
datadir=/data/mysql/3306/data

if test -z "$basedir"
then
  basedir=/usr/local/mysql
  bindir=/usr/local/mysql/bin
  if test -z "$datadir"
  then
    datadir=/data/mysql/3306/data
  fi
  sbindir=/usr/local/mysql/bin
  libexecdir=/usr/local/mysql/bin
else
  bindir="$basedir/bin"
  if test -z "$datadir"
  then
    datadir="$basedir/data"
  fi
  sbindir="$basedir/sbin"
  libexecdir="$basedir/libexec"
fi




使用配置文件/usr/local/mysql/support-files/mysql.server启动

[root@node01 ~]# /usr/local/mysql/support-files/mysql.server start
Starting MySQL................ SUCCESS!

[root@node01 ~]# /usr/local/mysql/support-files/mysql.server status
 SUCCESS! MySQL running (102015)
 
[root@node01 ~]# /usr/local/mysql/support-files/mysql.server stop
