MySQL 5.7.38安装审计插件 mysql-audit

MySQL版本众多，同样审计的软件众多，为什么使用 mysql-audit ，原因：老外的弄得，一直在维护，支持的MySQL版本多

安装MySQL

1.查看Linux服务器版本和glibc版本

[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)[root@localhost ~]# ldd --version
ldd (GNU libc) 2.17

4.安装MySQL

1.安装之前看是否安装过MySQL数据库

[root@localhost Desktop]# yum remove mysql
Loaded plugins: fastestmirror, langpacks
No Match for argument: mysql
No Packages marked for removal

2.查看是否有MySQL依赖


[root@localhost Desktop]# rpm -qa | grep mysql
[root@localhost Desktop]#

若有就卸载

//普通删除模式
rpm -e xxx(mysql_libs)
//强力删除模式,如果上述命令删除时，提示有依赖其他文件，则可以用该命令对其进行强力删除
rpm -e --nodeps xxx(mysql_libs)

4.检查是否有mariadb


[root@localhost Desktop]# rpm -qa | grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@localhost Desktop]#

若有就卸载


[root@localhost Desktop]# rpm -qa | grep mariadb
mariadb-libs-5.5.68-1.el7.x86_64
[root@localhost Desktop]# rpm -e --nodeps mariadb-libs
[root@localhost Desktop]# rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64
error: package mariadb-libs-5.5.68-1.el7.x86_64 is not installed
[root@localhost Desktop]#

5.安装mysql依赖包


[root@localhost Desktop]# yum install libaio
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile* base: mirrors.ustc.edu.cn* extras: mirrors.ustc.edu.cn* updates: mirrors.ustc.edu.cn

[root@localhost Desktop]#

6.解压MySQL的tar文件安装准备

 clear
[root@localhost Desktop]# tar -xvf mysql-5.7.38-linux-glibc2.12-x86_64.tar
mysql-test-5.7.38-linux-glibc2.12-x86_64.tar.gz
mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz
[root@localhost Desktop]# tar -zxvf mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz  
mysql-5.7.38-linux-glibc2.12-x86_64/bin/myisam_ftdump

mysql-5.7.38-linux-glibc2.12-x86_64/docs/INFO_SRC
[root@localhost Desktop]#

修改解压后路径名称

 [root@localhost Desktop]# ls
audit-plugin-mysql-5.7-1.1.13-1008-linux-x86_64.zip
mysql-5.7.38-linux-glibc2.12-x86_64

mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz
mysql-test-5.7.38-linux-glibc2.12-x86_64.tar.gz
[root@localhost Desktop]# mv mysql-5.7.38-linux-glibc2.12-x86_64 mysql
[root@localhost Desktop]#
[root@localhost Desktop]#

安装习惯把MySQL 移动到 /usr/local目录

 [root@localhost Desktop]# ls /usr/local/
bin  etc  games  include  lib  lib64  libexec  sbin  share  src
[root@localhost Desktop]#[root@localhost Desktop]# mv mysql /usr/local/
[root@localhost Desktop]# ls /usr/local/
bin  etc  games  include  lib  lib64  libexec  mysql  sbin  share  src
[root@localhost Desktop]# ls /usr/local/mysql/
bin  docs  include  lib  LICENSE  man  README  share  support-files
[root@localhost Desktop]#

切换到MySQL目录，创建相关用户名密码

  [root@localhost Desktop]# cd /usr/local/mysql/
[root@localhost mysql]# pwd
/usr/local/mysql
[root@localhost mysql]# ls
bin  docs  include  lib  LICENSE  man  README  share  support-files
[root@localhost mysql]# mkdir mysqld
[root@localhost mysql]# ls
bin  docs  include  lib  LICENSE  man  mysqld  README  share  support-files
[root@localhost mysql]#

mysql安装目录赋予权限

[root@localhost mysql]# ls

[root@localhost mysql]# pwd
/usr/local/mysql
[root@localhost mysql]#

创建mysql组和用户
创建组

[root@localhost mysql]#
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]#

创建用户(-s /bin/false参数指定mysql用户仅拥有所有权，而没有登录权限)

[root@localhost mysql]#
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -r -g mysql -s /bin/false mysql
[root@localhost mysql]#
[root@localhost mysql]#

将用户添加到组中

[root@localhost mysql]# clear
[root@localhost mysql]#
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -r -g mysql -s /bin/false mysql

[root@localhost mysql]#

修改 /etc/my.cnf 文件，如果没有文件就新建

[root@localhost mysql]# cd /etc/
[root@localhost etc]# ls | grep my.cnf
[root@localhost etc]#
[root@localhost etc]# pwd
/etc
[root@localhost etc]# touch my.cnf
[root@localhost etc]# ls -al | grep my.cnf
-rw-r--r--.   1 root root        0 May 16 18:54 my.cnf
[root@localhost etc]#

编辑 my.cnf文件
配置如下

[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=/usr/local/mysql
# 设置mysql数据库的数据的存放目录
datadir=/usr/local/mysql/mysqldb
# 允许最大连接数
max_connections=10000
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[client]
# 设置mysql客户端连接服务端时默认使用的端口

default-character-set=utf8

7.安装MySQL

进入MySQL的bin目录

[root@localhost etc]# cd /usr/local/mysql/bin/
[root@localhost bin]# pwd
/usr/local/mysql/bin

安装mysql，并记住初始化随机密码

[root@localhost bin]# ./mysqld --initialize --console

注意这一行

 [Note] A temporary password is generated for root@localhost: ..g0Xl1wB8u.

说明我的默认密码是，注意是 localhost冒号后面的

…g0Xl1wB8u.
在这里插入图片描述

启动mysql服务，切换目录，给权限

[root@localhost bin]# cd /usr/local/mysql/support-files
[root@localhost support-files]# chmod -R 777 /usr/local/mysql
[root@localhost support-files]#
[root@localhost support-files]#

启动MySQL

[root@localhost bin]# cd /usr/local/mysql/support-files
[root@localhost support-files]# chmod -R 777 /usr/local/mysql
[root@localhost support-files]#
[root@localhost support-files]# ./mysql.server start
Starting MySQL.Logging to '/usr/local/mysql/mysqldb/localhost.localdomain.err'.SUCCESS!
[root@localhost support-files]#

将mysql添加到系统进程中，就可以使用服务进程操作mysql了

[root@localhost support-files]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost support-files]#

设置mysql自启动

[root@localhost support-files]# chmod +x /etc/init.d/mysqld
[root@localhost support-files]# systemctl enable mysqld
mysqld.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld on
[root@localhost support-files]#

修改root用户登录密码，密码就是上面的随机字符串，我的是 …g0Xl1wB8u. 每个人随机的都不一样

[root@localhost bin]# pwd
/usr/local/mysql/bin
[root@localhost bin]# ./mysql -u root -p[root@localhost bin]# ./mysql -u root -p
Enter password:

Bye
[root@localhost bin]#
[root@localhost bin]#

重启服务且测试
命令1：systemctl restart mysql
命令2： service mysql restart
两条命令都可以重启MySQL

[root@localhost bin]#
[root@localhost bin]# service mysql restart
Redirecting to /bin/systemctl restart mysql.service
[root@localhost bin]#

查看MySQL启动状态

[root@localhost bin]#
[root@localhost bin]# cd ~/Desktop/
[root@localhost Desktop]# systemctl status mysql

8.防火墙，端口开放

查看所有端口

[root@localhost Desktop]# firewall-cmd --list-all
public (active)target: defaulticmp-block-inversion: nointerfaces: ens33sources:services: dhcpv6-client sshports:protocols:masquerade: noforward-ports:source-ports:icmp-blocks:rich rules:[root@localhost Desktop]#

开放3306端口 , --permanent 永久生效

[root@localhost Desktop]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost Desktop]#
[root@localhost Desktop]#  firewall-cmd --reload
success

看下自己的IP，连接测试

[root@localhost Desktop]# ifconfig | grep 192inet 192.168.1.106  netmask 255.255.255.0  broadcast 192.168.1.255inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255

4.安装审计插件mysql-audit

1.审计软件我已经下载了，上文有下载说明

[root@localhost Desktop]# ls -l | grep aud
-rw-r--r--. 1 root root     596787 Oct 12  2022 audit-plugin-mysql-5.7-1.1.13-1008-linux-x86_64.zip
[root@localhost Desktop]#
[root@localhost Desktop]#
[root@localhost Desktop]# pwd
/root/Desktop

2.解压软件

[root@localhost Desktop]# unzip audit-plugin-mysql-5.7-1.1.13-1008-linux-x86_64.zip
Archive:  audit-plugin-mysql-5.7-1.1.13-1008-linux-x86_64.zipcreating: audit-plugin-mysql-5.7-1.1.13-1008/creating: audit-plugin-mysql-5.7-1.1.13-1008/lib/inflating: audit-plugin-mysql-5.7-1.1.13-1008/lib/libaudit_plugin.soinflating: audit-plugin-mysql-5.7-1.1.13-1008/COPYINGinflating: audit-plugin-mysql-5.7-1.1.13-1008/THIRDPARTY.txtinflating: audit-plugin-mysql-5.7-1.1.13-1008/README.txtinflating: audit-plugin-mysql-5.7-1.1.13-1008/plugin-name.txtcreating: audit-plugin-mysql-5.7-1.1.13-1008/utils/inflating: audit-plugin-mysql-5.7-1.1.13-1008/utils/offset-extract.sh
[root@localhost Desktop]#

3.登录进入MySQL，找到你的插件所在目录

[root@localhost Desktop]# pwd
/root/Desktop
[root@localhost Desktop]# cd /usr/local/mysql/bin/
[root@localhost bin]# ./mysql -uroot -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.

owners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql>mysql> show global variables like 'plugin_dir';
+---------------+------------------------------+
| Variable_name | Value                        |
+---------------+------------------------------+
| plugin_dir    | /usr/local/mysql/lib/plugin/ |
+---------------+------------------------------+
1 row in set (0.01 sec)mysql>

4.我们的MySQL插件目录是 /usr/local/mysql/lib/plugin/

把插件复制到MySQL的插件目录，并修改权限和所有者

mysql>
mysql> quit
Bye
[root@localhost bin]# cd ~/Desktop/audit-plugin-mysql-5.7-1.1.13-1008/lib/
[root@localhost lib]#
[root@localhost lib]# cp libaudit_plugin.so /usr/local/mysql/lib/plugin/
[root@localhost lib]# chmod +x /usr/local/mysql/lib/plugin/libaudit_plugin.so
[root@localhost lib]# chown mysql:mysql /usr/local/mysql/lib/plugin/libaudit_plugin.so
[root@localhost lib]#
[root@localhost lib]#

5.获取偏移量信息

找到自己的mysqld 文件，可使用 whereis mysqld
但是我们是源码包安装的 mysqld 位置 : /usr/local/mysql/bin/

[root@localhost Desktop]# pwd
/root/Desktop
[root@localhost Desktop]# ls  /usr/local/mysql/bin/ | grep mysqld
mysqld
mysqld-debug
mysqld_multi
mysqld_safe
mysqldump
mysqldumpslow
[root@localhost Desktop]#

进入插件的解压目录 ,添加权限，然后获取数值

[root@localhost Desktop]# cd audit-plugin-mysql-5.7-1.1.13-1008/utils/
[root@localhost utils]# ls -al
total 8
drwxr-xr-x. 2 root root   31 Sep  6  2022 .
drwxr-xr-x. 4 root root  108 Sep  6  2022 ..
-rw-r--r--. 1 root root 4726 Sep  6  2022 offset-extract.sh
[root@localhost utils]# chmod +x offset-extract.sh
[root@localhost utils]#
[root@localhost utils]# ls -al
total 8
drwxr-xr-x. 2 root root   31 Sep  6  2022 .
drwxr-xr-x. 4 root root  108 Sep  6  2022 ..
-rwxr-xr-x. 1 root root 4726 Sep  6  2022 offset-extract.sh
[root@localhost utils]# ./offset-extract.sh  /usr/local/mysql/bin/mysqld
//offsets for: /usr/local/mysql/bin/mysqld (5.7.38)
{"5.7.38","adf0327064da666263ab1ba6b3cf55bb", 7832, 7880, 3640, 4800, 456, 360, 0, 32, 64, 160, 544, 7996, 4368, 3648, 3656, 3660, 6080, 2072, 8, 7064, 7104, 7088, 13480, 148, 672, 0},
[root@localhost utils]#

6.修改MySQL配置文件

[root@localhost utils]# cd /etc/
[root@localhost etc]# vim my.cnf

在这里插入图片描述

这是我的my.cnf完整配置

[root@localhost etc]# cat my.cnf
[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=/usr/local/mysql
# 设置mysql数据库的数据的存放目录
datadir=/usr/local/mysql/mysqldb
# 允许最大连接数
max_connections=10000
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password#审计offsets 不要乱配置
audit_offsets=7832, 7880, 3640, 4800, 456, 360, 0, 32, 64, 160, 544, 7996, 4368, 3648, 3656, 3660, 6080, 2072, 8, 7064, 7104, 7088, 13480, 148, 672, 0
#审计操作命令
# 如果不指定audit_record_cmds，所有DDL，DML全记录
audit_record_cmds='select,insert,delete,update,create,drop,alter,grant,truncate'
#审计开关
audit_json_file=on
#加载审计第三方库
plugin-load=AUDIT=libaudit_plugin.so
#审计日志路径
audit_json_log_file=/var/log/mysql_audit.json[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8
[root@localhost etc]#

7.安装mysql-audit插件

连接MySQL数据库，并查看安装的所有插件

[root@localhost log]# cd ~/Desktop/
[root@localhost Desktop]# cd /usr/local/mysql/bin/
[root@localhost bin]# ./mysql -uroot -p
Enter password:

8.连接数据库测试

在这里插入图片描述
我在这里添加了两条数据

[root@localhost Desktop]# cd /var/log/
[root@localhost log]# ls | grep mysql_audit.json
[root@localhost log]#
[root@localhost log]# ls | grep mysql_audit.json
[root@localhost log]#
[root@localhost log]#
[root@localhost log]#
[root@localhost log]#

但是我到这个目录下，找不到 mysql_audit.json
我们只需要把这个文件创建出来，然后修改所有者和所属组就可以了

[root@localhost log]# ls | grep mysql_audit.json
[root@localhost log]#
[root@localhost log]#
[root@localhost log]# touch mysql_audit.json
[root@localhost log]#
