1.查看操作系统
[root@localhost ~]# uname -a
Linux localhost.localdomain 4.19.90-89.11.v2401.ky10.x86_64 #1 SMP Tue May 7 18:33:01 CST 2024 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# cat /etc/os-release
NAME="Kylin Linux Advanced Server"
VERSION="V10 (Halberd)"
ID="kylin"
VERSION_ID="V10"
PRETTY_NAME="Kylin Linux Advanced Server V10 (Halberd)"
ANSI_COLOR="0;31"

2.获取mysql安装介质
mysql-5.7.42-linux-glibc2.12-x86_64.tar.gz

3.创建mysql用户和用户组(系统已经创建不需要创建)
[root@localhost soft]#groupadd mysql
[root@localhost soft]#useradd -g mysql mysql
[root@localhost soft]#passwd mysql

4.创建安装主目录
[root@localhost soft]#mkdir -p /home/middle/

5.下载解压安装
[root@localhost soft]# tar -xvf mysql-5.7.42-linux-glibc2.12-x86_64.tar.gz
[root@localhost soft]# mv mysql-5.7.42-linux-glibc2.12-x86_64 /home/middle/mysql57

6.创建相应的目录
[root@node1 mysql8]# cd /home/middle/mysql57
[root@localhost mysql8]# mkdir data ##数据文件目录
[root@localhost mysql8]# mkdir conf ## 配置文件目录
[root@localhost mysql8]# mkdir -p mysqllog/relaylog ##主从环境relaylog
[root@localhost mysql8]# mkdir -p mysqllog/logfile ##错误日志文件
[root@localhost mysql8]# mkdir -p mysqllog/binlog ##binlog文件
[root@localhost mysql8]# mkdir -p secure_file ##secure_file_priv参数指定路

7.初始化数据库
root账户下
[root@localhost mysql57]# cd /home/middle/mysql57/bin
./mysqld --initialize --user=mysql --basedir=/home/middle/mysql57 --datadir=/home/middle/mysql57/data --lc_messages_dir=/home/middle/mysql57/share --lc_messages=en_US

8.准备配置文件

root@db:/home/middle/mysql57/conf# more my.cnf 
[mysqld]

basedir=/home/middle/mysql57
datadir=/home/middle/mysql57/data

quick
max_allowed_packet = 32M
[myisamchk]
key_buffer_size = 8M
sort_buffer_size = 8M
read_buffer = 4M
write_buffer = 4M

9.生成错误日志文件
[root@localhost conf]# echo>/home/middle/mysql57/mysqllog/logfile/mysql-err.log

10.修改目录权限
[root@localhost mha]# cd /home/middle
[root@localhost opt]# chown -R mysql:mysql ./mysql57

11.启动
(在root用户下执行)
[root@node1 opt]# /home/middle/mysql57/bin/mysqld_safe --defaults-file=/home/middle/mysql57/conf/my.cnf --user=mysql &

12.登陆数据库修改相应用户密码
[root@localhost middle]# /home/middle/mysql57/bin/mysql -h localhost -uroot -P13306 -p

mysql> set password=password('mysql');
Query OK, 0 rows affected, 1 warning (0.05 sec)
