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
authpriv.* /var/log/secure

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

$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal

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
最后希望大家提意见、转发、评论和交流!!!
