mysql加载audit失败_MySQL5.5 安装mcafee mysql-audit插件 不成功

安装步骤还是比较简单的，只有几步：

1)查看插件目录

mysql> SHOW GLOBAL VARIABLES LIKE ‘plugin_dir‘;+---------------+--------------------+

| Variable_name | Value |

+---------------+--------------------+

| plugin_dir | /mysql/lib/plugin/ |

+---------------+--------------------+

1 row in set (0.00 sec)

2)复制下载的so文件至plugin_dir

3)安装插件，不报错即为成功

mysql> INSTALL PLUGIN AUDIT SONAME ‘libaudit_plugin.so‘;

4)可以查看安装的版本

mysql> SHOW GLOBAL STATUS LIKE ‘AUDIT_version‘;

5)开启审计

mysql> SET GLOBAL audit_json_file=ON;

问题是，在第三步安装插件时总是不成功，报错

mysql> INSTALL PLUGIN AUDIT SONAME ‘libaudit_plugin.so‘;

ERROR1123 (HY000): Can‘t initialize function‘AUDIT‘; Plugin initialization function failed.

查看错误日志，注意到offsets_by_version: 1，即为打开Offsets检验，但提示Offsets检验失败

关闭audit_offsets_by_version后再试试，将audit_offsets_by_version=OFF写入/etc/my.cnf，重启数据库，再安装插件，仍然报错

由于我的是percona server，另外需要指明mysqld.debug路径来计算，可能还需要mysqld-debug.debug

# ./offset-extract.sh /mysql/bin/mysqld /usr/lib/debug/usr/sbin/mysqld.debug//offsets for: /mysql/bin/mysqld (5.5.21-log)

{"5.5.21","325edbcbbfaabdddd7b22e3036c2d774", 6584, 6632, 4120, 4632, 104, 2608, 96, 0, 32, 104},

# ./offset-extract.sh /mysql/bin/mysqld /usr/lib/debug/usr/sbin/mysqld-debug.debug//offsets for: /mysql/bin/mysqld (5.5.21-log)

{"5.5.21","325edbcbbfaabdddd7b22e3036c2d774", 6608, 6656, 4136, 4656, 104, 2608, 96, 0, 32, 104},

加入my.cnf的插件参数：

plugin-load=AUDIT=libaudit_plugin.so

audit_json_file=1audit_json_socket_name=/mysql/data/audit.sock

audit_json_socket=OFF

audit_json_file=ON

audit_json_log_file=/mysql/data/audit.log

audit_record_cmds=connect,update,delete

audit_validate_checksum=OFF

audit_offsets=6608, 6656, 4136, 4656, 104, 2608, 96, 0, 32, 104

mysqld.debug和mysqld-debug.debug的offsets我都加入my.cnf试了下，仍然报错，崩溃！

问题出在哪儿呢，该怎么配置呢？这里先记一笔！
