主机角色说明

5、foundation通过Rsyslog搭建集中日志服务器

5.1 数据存放在日志文本文件中

5.1.1 检查有没有安装rsyslog (默认都是安装了的并且开机自启动)

5.1.2 配置文件解析

服务器端配置文件配置选项解析:
[root@localhost samba]# vim /etc/rsyslog.conf
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal

 #####开启udp接收日志
$ModLoad imudp
$UDPServerRun 514
$template RemoteHost,"/data/syslog/%$YEAR%-%$MONTH%-%$DAY%/%FROMHOST-IP%.log"   
*.*  ?RemoteHost
& ~
####开启tcp协议接受日志
$ModLoad imtcp
$InputTCPServerRun 514

$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

#######启用/etc/rsyslog.d/*.conf目录下所有以.conf结尾的配置文件
$IncludeConfig /etc/rsyslog.d/*.conf     

$OmitLocalLogging on
$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

a:$template Remote,"/date/log/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"
 
b.$template Remote,"/data/log/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"  定义模板,接受日志文件路径,区分了不同主机的日志
 
c.:fromhost-ip, !isequal, "127.0.0.1" ?Remote 过滤server 本机的日志
 
最简单的办法;
$template myFormat,"%timestamp% %fromhost-ip%%msg%\n"
$template Remote,"/var/log/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"
:fromhost-ip, !isequal, "127.0.0.1" -?Remote;myFormat

local7.*                                                /var/log/boot.log

5.2 rsyslog使用数据库作为存储介质

注意:客户端配置和前面一致即可。

5.2.1 配置

服务端仅做下面的配置即可。

1 [root@foundation ~]# yum install rsyslog-mysql

使用脚本创建数据库:

[root@foundation ~]# mysql -ursyslog -h127.0.0.1 -p </usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql
Enter password:

为Rsyslog创建数据库账户

mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password_length=4;
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL ON Syslog.* TO \'rsyslog\'@\'127.0.0.1\' IDENTIFIED BY \'test\';
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> GRANT ALL ON Syslog.* TO \'rsyslog\'@\'localhost\' IDENTIFIED BY \'test\';
Query OK, 0 rows affected, 1 warning (0.01 sec)


mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

在/etc/rsyslog.conf中加入如下配置

重启rsyslogd

1 systemctl restart rsyslog.service
2 systemctl enable rsyslog.service

5.2.2 测试

使用rsyslog用户登录数据库后查看

部分截图

5.2.3 附MySQL导入导出SQL文件

导出整个数据库中的所有数据:
1、在linux命令行下输入:
mysqldump -u userName -p dabaseName > fileName.sql

fileName.sql最好加上路径名

导出数据库中的某个表的数据:
mysqldump -u userName -p dabaseName tableName > fileName.sql

导出整个数据库中的所有的表结构

在linux命令行下输入:
mysqldump -u userName -p -d dabaseName > fileName.sql

注意:是加了-d

导出整个数据库中某个表的表结构
在linux命令行下输入:
mysqldump -u userName -p -d dabaseName tableName > fileName.sql

注意:是加了-d

导入mysql方法1(测试好用)
进入linux命令命令行下:
mysql -u root -p 回车 输入密码
mysql> use weifang
mysql> source /home/user/data/fileName.sql

注意fileName.sql要有路径名,例如:source /home/user/data/fileName.sql

导入mysql方法2(测试一次,导入数据后占空间异常大,还需验证)
进入linux命令命令行下:
mysql -uroot -p database < fileName.sql

注意fileName.sql要有路径名
