部署堡垒机2——安装MySQL8.0.32或8.0.28+

MySQL的三大版本

a）MySQL Enterprise Edition：企业版本（付费）
b）MySQL Cluster CGE：高级集群版（收费）
c）MySQL Community Server：社区版（开源）

登录MySQL官网

https://www.mysql.com/downloads/

点击“DOCUMENTATION”——“MySQL Server”——“Installing and Upgrading MySQL”——“Installing MySQL on Linux”

点击：Installing MySQL on Linux Using the MySQL Yum Repository

点击：https://dev.mysql.com/downloads/repo/yum/

点击linux 7——download

右键复制链接地址

wget https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm

操作步骤如下：

cd /opt/
wget https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm
yum install mysql80-community-release-el7-7.noarch.rpm
gcc -v
yum update -y
yum list | grep mysql
yum install -y mysql-community-server

root@jumpserver-app-t01:/opt#mysql -V
mysql  Ver 8.0.32 for Linux on x86_64 (MySQL Community Server - GPL)

启动mysqld服务

root@jumpserver-app-t01:/opt/mysql#systemctl start mysqld
root@jumpserver-app-t01:/opt/mysql#systemctl status mysqld
root@jumpserver-app-t01:/opt/mysql#systemctl enable mysqld
root@jumpserver-app-t01:/opt/mysql#

找到mysql的默认密码在这里：root@localhost: si<%<s%x7.On

root@jumpserver-app-t01:/var/log#cat /var/log/mysqld.log

root@jumpserver-app-t01:/var/log#

此时需要到mysql中使用临时密码登录，并修改临时密码，因为临时密码是不可用的

mysql -uroot -p
si<%<s%x7.On

mysql> alter user root@'localhost' identified by'*******@666';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;    #刷新数据表信息后exit退出
Query OK, 0 rows affected (0.00 sec)
mysql>exit
Bye

PS：简单的MySQL安装方法，去阿里源中找到mysql-community-server-8.0.28-1.el7.x86_64.rpm，下载到本地后，然后yum localinstall ./*

这样既能安装该组件，还能安装所需依赖

cd /opt
mkdir mysql
cd mysql
wget https://mirrors.aliyun.com/mysql/MySQL-8.0/mysql-community-server-8.0.28-1.el7.x86_64.rpm?spm=a2c6h.25603864.0.0.5e8670b2c1XZn4
yum localinstall ./*

后面一路选Y安装即可

systemctl start mysqld
systemctl status mysqld
systemctl enable mysqld

分割线

1、创建JumpServer数据库，并存储为中文支持格式

root@jumpserver-app-t01.novalocal:/jumpserver/mysql_rpm#mysql -uroot -p
Enter password:

mysql> create database jumpserver default charset 'utf8' collate 'utf8_bin';
Query OK, 1 row affected, 2 warnings (0.00 sec)
mysql>

2、创建用户 @是占位符、%是允许该账号在任何位置都可以登录

mysql> create user 'jumpserver'@'%' IDENTIFIED BY '******66666';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

###mysql登录报错时用这个命令
alter user jumpserver@'%' identified with mysql_native_password by '******66666';
###登录报错内容如下：
root@jumpserver-app-p01:/root#mysql -h 10.15.32.10 -P 3306 -u jumpserver -p
Enter password:
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

3、给JumpServer用户授予访问JumpServer数据库的权限。

#grant授权'jumpserver'@'%'用户在使用identified by 'chaoge888'密码时，允许访问jumpserver.*所有的表，的all privileges所有权限“添删改查”
mysql> grant all privileges on jumpserver.* to 'jumpserver'@'%' ;
Query OK, 0 rows affected (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>exit
Bye

MySQL数据库基础常用命令8.0版本适用

#查询数据库账户
select user, host from mysql.user;
#删除账户 'zabbix'
drop user 'zabbix'@'%';
#查询数据库
show databases;
#删除数据库zabbix;
drop database zabbix;
#修改账户密码
alter user 'zabbix'@'%' identified  by 'Qqqq1234.com';

ubuntu安装的mysql，默认配置文件保存在/etc/mysql/mysql.conf.d/mysqld.cnf

root@JumpServer-DB-P01:/opt# cat /etc/mysql/mysql.conf.d/mysqld.cnf
#
# The MySQL database server configuration file.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

# For explanations see
