syslog-ng 和 nginx 日志记录到 mysql

几天前我问过 如何将 php 和 nginx 日志记录到集中式 MySQL 数据库，而m0ntassar给出了完美的答案:) 加油！

我现在面临的问题是我似乎无法让它工作。

syslog-ng 版本：

# syslog-ng --version
syslog-ng 3.2.5

这是我的 nginx 日志格式：

log_format      main    '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';

syslog-ng 源：

source nginx { file( "/var/log/nginx/tg-test-3.access.log"
                     follow_freq(1)
                     flags(no-parse)
     );
};

syslog-ng 目标：

destination d_sql {
sql(type(mysql)
host("127.0.0.1") username("syslog") password("superpasswd")
database("syslog")
table("nginx")
columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_    referer","http_user_agent","http_x_forwarded_for")
values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR"));
};

用于测试目的的 MySQL 表：

CREATE TABLE `nginx` (
  `remote_addr` varchar(100) DEFAULT NULL,
  `remote_user` varchar(100) DEFAULT NULL,
  `time` varchar(100) DEFAULT NULL,
  `request` varchar(100) DEFAULT NULL,
  `status` varchar(100) DEFAULT NULL,
  `body_bytes_sent` varchar(100) DEFAULT NULL,
  `http_referer` varchar(100) DEFAULT NULL,
  `http_user_agent` varchar(100) DEFAULT NULL,
  `http_x_forwarded_for` varchar(100) DEFAULT NULL,
  `time_local` text,
  `datetime` text,
  `host` text,
  `program` text,
  `pid` text,
  `message` text
) ENGINE=InnoDB DEFAULT CHARSET=latin1

现在出错的第一件事就是当我重新启动 syslog-ng 时：

# /etc/init.d/syslog-ng restart
Stopping syslog-ng:                                        [  OK  ]
Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future;
                                                           [  OK  ]

我尝试创建一个文件目标并且一切正常，然后我尝试用以下方法替换我的目标：

destination d_sql {
sql(type(mysql)
host("127.0.0.1") username("syslog") password("kosmodromas")
database("syslog")
table("nginx")
columns("datetime", "host", "program", "pid", "message")
values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY")
indexes("datetime", "host", "program", "pid", "message"));
};

它确实工作了，并且正在将内容写入mysql，

问题是我想要以与 nginx 日志格式完全相同的格式写入内容。

我认为我遗漏了一些非常简单的东西，或者我需要在源和目标之间进行一些解析。

任何帮助都感激不尽 ：）

我可以帮您将 nginx 访问日志写入 postgres。开始吧 Nginx 日志格式

log_format logtodb '$time_iso8601;$http_host;$remote_addr;$http_x_forwarded_for;$request_method;$request;$status;$body_bytes_sent;$http_referer;$request_time;$upstream_http_x_cache;$uri;$upstream_addr;$host;$upstream_response_length;$upstream_status;$server_name;$newurl;$upstream_response_time';

access_log /var/log/nginx/access_logtodb.log logtodb; 我们走吧。

配置 syslog-ng

nano /etc/syslog-ng/syslog.ng

     );
};




parser p_nginx_acceess_log {
    csv-parser(columns("NGINX_TIME", "NGINX_http_host", "NGINX_remote_addr", "NGINX_http_x_forwarded_for", "NGINX_request", "NGINX_request_method","NGINX_status", "NGINX_body_bytes_sent", "NGINX_http_referer", "NGINX_request_time", "NGINX_upstream_http_x_cache", "NGINX_uri", "NGINX_upstream_addr", "NGINX_host", "NGINX_upstream_response_length", "NGINX_upstream_status", "NGINX_server_name", "NGINX_newurl", "NGINX_upstream_response_time")

         delimiters(";")
         quote-pairs('""[]')
         );
};



destination d_postgres_nginx_acceess_log{
  sql(type(pgsql)
  host("10.12.1.1")  port("5432") username("postgres") password("A1s2gdfgdfgdgdfgd")

  table("access_log_nginx_223")

  indexes("NGINX_request", "NGINX_uri", "NGINX_server_name"));

};

log {source(nginx_acceess_log);  parser(p_nginx_acceess_log); destination(d_postgres_nginx_acceess_log); };

安装要发送到数据库的数据包

apt-get install libdbd-pgsql -y

配置 db-postgres 创建数据库 nginx_logs。在 pg_hba.conf 中授予访问权限
