mysql-8.0.40二进制单节点部署

1、下载二进制包

https://dev.mysql.com/downloads/mysql/
选择 mysql-8.0.40-linux-glibc2.28-x86_64.tar.xz

2、部署

cd /opt
tar xf mysql-8.0.40-linux-glibc2.28-x86_64.tar.xz
groupadd mysql
useradd -g mysql -s /sbin/nologin -M mysql
mkdir /data/mysql-8.0.40/{data,tmp,logs} -p
chown -R mysql.mysql /opt/mysql-8.0.40-linux-glibc2.28-x86_64
chown -R mysql.mysql /data/mysql-8.0.40
chmod -R 750 /data/mysql-8.0.40/data
ln -s mysql-8.0.40-linux-glibc2.28-x86_64 mysql
ln -s /opt/mysql/bin/* /usr/local/sbin/

3、vim /opt/mysql/my-8.0.40.cnf

4、初始化数据库

/opt/mysql/bin/mysqld --defaults-file=/opt/mysql/my-8.0.40.cnf --initialize --user=mysql --datadir=/data/mysql-8.0.40/data

5、启动实例

/opt/mysql/bin/mysqld_safe --defaults-file=/opt/mysql/my-8.0.40.cnf &

6、登录实例，需要使用初始化过程中生成的随机密码

grep password /data/mysql-8.0.40/logs/error.log
2025-01-16T15:42:06.420055+08:00 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: xE+4wr#Wl-.&

/opt/mysql/bin/mysql -uroot -S /tmp/mysql.sock -p

// 修改密码
mysql> ALTER USER user() IDENTIFIED BY 'mysql';
Query OK, 0 rows affected (0.00 sec)

7、开机自启动

cp /opt/mysql/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
chmod +x /etc/init.d/mysql
chkconfig --list
chkconfig --add mysql
chkconfig --list
