运行环境：Centos 7.5+MariaDB10.3.8
1.查询默认的plugin_dir:
MariaDB [(none)]> show variables like 'plugin_dir';
+---------------+------------------------------+
| Variable_name | Value |
+---------------+------------------------------+
| plugin_dir | /usr/local/mysql/lib/plugin/ |
+---------------+------------------------------+
1 row in set (0.001 sec)
2.插件的安装和卸载：
MariaDB [(none)]> INSTALL SONAME 'server_audit';
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> UNINSTALL PLUGIN server_audit;
Query OK, 0 rows affected, 1 warning (0.000 sec)
MariaDB [(none)]> install plugin server_audit soname 'server_audit.so';
3.查看的查看：
MariaDB [(none)]> select PLUGIN_NAME,PLUGIN_VERSION,PLUGIN_STATUS,PLUGIN_MATURITY,PLUGIN_AUTH_VERSION from information_schema.plugins where plugin_name='SERVER_AUDIT';
+--------------+----------------+---------------+-----------------+---------------------+
| PLUGIN_NAME | PLUGIN_VERSION | PLUGIN_STATUS | PLUGIN_MATURITY | PLUGIN_AUTH_VERSION |
+--------------+----------------+---------------+-----------------+---------------------+
| SERVER_AUDIT | 1.4 | ACTIVE | Stable | 1.4.4 |
+--------------+----------------+---------------+-----------------+---------------------+
1 row in set (0.000 sec)
可以查看到插件的版本为1.4.4版本，为MariaDB 中审计插件最新版本且最稳定的版本。
或者：
MariaDB [(none)]> show plugins;
+-------------------------------+----------+--------------------+-----------------+---------+
| Name | Status | Type | Library | License |
+-------------------------------+----------+--------------------+-----------------+---------+
| binlog | ACTIVE | STORAGE ENGINE | NULL | GPL |
....
| SERVER_AUDIT | ACTIVE | AUDIT | server_audit.so | GPL |
+-------------------------------+----------+--------------------+-----------------+---------+
54 rows in set (0.001 sec)
4.写入配置文件my.cnf:
[mysqld]
plugin_load=server_audit=server_audit.so
server_audit=FORCE_PLUS_PERMANENT #禁止uninstall
5.查看审计的参数：
MariaDB [(none)]> show variables like 'server_audit%';
+-------------------------------+-----------------------+
| Variable_name | Value |
+-------------------------------+-----------------------+
| server_audit_events | |
| server_audit_excl_users | |
| server_audit_file_path | server_audit.log |
| server_audit_file_rotate_now | OFF |
| server_audit_file_rotate_size | 1000000 |
| server_audit_file_rotations | 9 |
| server_audit_incl_users | |
| server_audit_logging | OFF |
| server_audit_mode | 0 |
| server_audit_output_type | file |
| server_audit_query_log_limit | 1024 |
| server_audit_syslog_facility | LOG_USER |
| server_audit_syslog_ident | mysql-server_auditing |
| server_audit_syslog_info | |
| server_audit_syslog_priority | LOG_INFO |
+-------------------------------+-----------------------+
15 rows in set (0.001 sec)
server_audit_events：指定记录事件的类型，可以用逗号分隔的多个值(connect,query,table)，如果开启了查询缓存(query cache)，查询直接从查询缓存返回数据，将没有table记录。
可有选项有：CONNECT、QUERY、TABLE、QUERY_DDL、QUERY_DML、QUERY_DML_NO_SELECT、QUERY_DCL。
server_audit_excl_users：该列表的用户行为将不记录，connect将不受该设置影响。
server_audit_file_path：如server_audit_output_type为FILE，使用该变量设置存储日志的文件，可以指定目录，默认存放在数据目录的server_audit.log文件中。
server_audit_file_rotate_now：强制日志文件轮转
server_audit_file_rotate_size：限制日志文件的大小
server_audit_file_rotations：指定日志文件的数量，如果为0日志将从不轮转
server_audit_incl_users：指定哪些用户的活动将记录，connect将不受此变量影响，该变量比server_audit_excl_users优先级高。
server_audit_mode：标识版本，用于开发测试
server_audit_output_type：指定日志输出类型，可为SYSLOG或FILE
server_audit_logging：启动或关闭审计
server_audit_query_log_limit:查询日志的限制。
server_audit_syslog_facility：默认为LOG_USER，指定facility
server_audit_syslog_ident：设置ident，作为每个syslog记录的一部分
server_audit_syslog_info：指定的info字符串将添加到syslog记录
server_audit_syslog_priority：定义记录日志的syslogd priority。
以上参数均是全局参数并且可以动态修改。
MariaDB [(none)]> set global server_audit_events='CONNECT,QUERY,TABLE,QUERY_DDL,QUERY_DML,QUERY_DCL';
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global server_audit_logging=on;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global server_audit_file_path ="/data/mysql/node1/node1_audit.log";
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global server_audit_file_rotate_size=200000000;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global server_audit_file_rotations=200;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> set global server_audit_file_rotate_now=ON;
Query OK, 0 rows affected (0.001 sec)
同时将上述参数配置到配置文件以防重启MySQL生效：
[mysqld]
plugin_load=server_audit=server_audit.so
server_audit=FORCE_PLUS_PERMANENT
server_audit_logging=on
server_audit_events='CONNECT,QUERY,TABLE,QUERY_DDL,QUERY_DML,QUERY_DCL'
server_audit_file_path ="/data/mysql/node1/node1_audit.log";
server_audit_file_rotate_size=200000000
server_audit_file_rotations=200
server_audit_file_rotate_now=ON
自定义后的配置：
MariaDB [(none)]> show variables like 'server_audit%';
+-------------------------------+---------------------------------------------------+
| Variable_name | Value |
+-------------------------------+---------------------------------------------------+
| server_audit_events | CONNECT,QUERY,TABLE,QUERY_DDL,QUERY_DML,QUERY_DCL |
| server_audit_excl_users | |
| server_audit_file_path | /data/mysql/node1/node1_audit.log |
| server_audit_file_rotate_now | OFF |
| server_audit_file_rotate_size | 200000000 |
| server_audit_file_rotations | 200 |
| server_audit_incl_users | |
| server_audit_logging | ON |
| server_audit_mode | 0 |
| server_audit_output_type | file |
| server_audit_query_log_limit | 1024 |
| server_audit_syslog_facility | LOG_USER |
| server_audit_syslog_ident | mysql-server_auditing |
| server_audit_syslog_info | |
| server_audit_syslog_priority | LOG_INFO |
+-------------------------------+---------------------------------------------------+
15 rows in set (0.002 sec)
--配置完毕后需要查看审计的状态数据：
MariaDB [(none)]> SHOW STATUS LIKE 'server_audit%';
+----------------------------+-----------------------------------+
| Variable_name | Value |
+----------------------------+-----------------------------------+
| Server_audit_active | ON |
| Server_audit_current_log | /data/mysql/node1/node1_audit.log |
| Server_audit_last_error | |
| Server_audit_writes_failed | 0 |
+----------------------------+-----------------------------------+
4 rows in set (0.001 sec)
通过将以上活动监控起来之后我们可以在指定的路径下查看日志信息来审计MySQL的活动！
