将nginx的access.log访问日志发送到rsyslog服务器并写入数据库

nginx.conf（将原日志路径改为rsyslog服务器地址）

access_log syslog:server=10.10.14.64:514,facility=local6 main;

如果需要入库需要安装相应数据库的依赖包；mysql依赖：yum install -y rsyslog-mysql pgsql依赖：yum install -y rsyslog-pgsql 还有很多其他依赖可以用 yum list rsyslog-* 进行查看

用 rpm -ql rsyslog-mysql 或 rpm -ql rsyslog-pgsql 来查看数据库脚本文件

查出来的大概是 /usr/share/doc/rsyslog/pgsql-createDB.sql，这个sql中有建库建表语句
