一、快速安装过程
useradd mysql -s /sbin/nologin -M
mkdir /data1/mariadb/{data,logs,tmp,undolog,binlog}
cd /data1;chown -R mysql.mysql mariadb
tar xf mariadb-10.2.10-linux-glibc_214-x86_64.tar.gz -C /usr/local/
cd /usr/local;ln -sv mariadb-10.2.10-linux-glibc_214-x86_64 mysql
cp /etc/my.cnf /usr/local/mysql/.my.cnf
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data1/mariadb/data --defaults-file=./.my.cnf
启动命令：
启动方式一： /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
启动方式二：cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql; chmod +x /etc/init.d/mysql; /etc/init.d/mysql start| service mysql start
启动方式三：cp support-files/systemd/mariadb.service /usr/lib/systemd/system/mariadb.service; systemctl start mariadb
二、warning日志处理
启动mariadb服务后 发现一直出现大量的日志:
发现原因是mariadb配置文件/etc/my.cnf 开启了线程池参数导致的问题
#thread_handling = pool-of-threads
#thread_pool_max_threads = 1200
#thread_pool_size = 128
#thread_pool_stall_limit = 10
关闭上面的参数停止输出上述warning日志
三、开启审计日志插件
install plugin server_audit soname 'server_audit.so';
set global server_audit_file_path='/data/mariadb/logs';
set global server_audit_events='connect,QUERY,table';
set global server_audit_file_rotate_size=104857600;
set global server_audit_file_rotations=100;
set global server_audit_excl_users='root';
set global server_audit_logging=on;
检查审计日志内容:
[root@tidb05 ~]# mysql -uwujianwei -h 127.0.0.1 -p'wujianwei' -e "select user,host from mysql.user;"
[root@tidb05 ~]# grep -w 'wujianwei' /data1/mariadb/logs/server_audit.log
20220404 20:09:21,tidb05,wujianwei,127.0.0.1,1828,0,CONNECT,,,0
20220404 20:09:21,tidb05,wujianwei,127.0.0.1,1828,26,QUERY,,'select @@version_comment limit 1',0
20220404 20:09:21,tidb05,wujianwei,127.0.0.1,1828,27,READ,mysql,user,
20220404 20:09:21,tidb05,wujianwei,127.0.0.1,1828,27,QUERY,mysql,'select user,host from mysql.user',0
20220404 20:09:21,tidb05,wujianwei,127.0.0.1,1828,0,DISCONNECT,,,0
四、开启审计日志报错分析
执行sql指令：
set global server_audit_events='connect,QUERY_DML_NO_SELECT,QUERY_DDL,QUERY_DCL,table';
报错如下:
2022-04-04 20:02:36 140204444202752 [ERROR] /usr/local/mysql/bin/mysqld: Error while setting value 'connect,QUERY_DML_NO_SELECT,QUERY_DDL,QUERY_DCL,table' to 'server-audit-events'
问题分析：
从官网得知：
https://mariadb.com/kb/en/mariadb-audit-plugin-log-settings/
在 MariaDB Audit Plugin version 1.4.4版本才出现QUERY_DML_NO_SELECT 这个参数
server_audit: MariaDB Audit Plugin version 1.4.2 STARTED 目前版本的审计插件是不支持 QUERY_DML_NO_SELECT 这个过滤参数的，所以报错。
