5、foundation通過Rsyslog搭建集中日志服務器
5.1 數據存放在日志文本文件中
5.1.1 檢查有沒有安裝rsyslog （默認都是安裝了的並且開機自啟動）
5.1.2 配置文件解析
服務器端配置文件配置選項解析： [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 #####開啟udp接收日志 $ModLoad imudp $UDPServerRun 514 $template RemoteHost,"/data/syslog/%$YEAR%-%$MONTH%-%$DAY%/%FROMHOST-IP%.log" *.* ?RemoteHost & ~ ####開啟tcp協議接受日志 $ModLoad imtcp $InputTCPServerRun 514 $WorkDirectory /var/lib/rsyslog $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat #######啟用/etc/rsyslog.d/*.conf目錄下所有以.conf結尾的配置文件 $IncludeConfig /etc/rsyslog.d/*.conf $OmitLocalLogging on $IMJournalStateFile imjournal.state *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg :omusrmsg:* uucp,news.crit /var/log/spooler local7.* /var/log/boot.log local0.* /etc/keepalived/keepalived.log

5.1.3 客戶端重要配置
[root@rhel7 log]# grep -v "^#" /etc/rsyslog.conf | grep -v "^$" $ModLoad imuxsock # provides support for local system logging (e.g. via logger command) $ModLoad imjournal # provides access to the systemd journal $template myFormat,"%timestamp% %fromhost-ip% %msg%\n" $WorkDirectory /var/lib/rsyslog $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $IncludeConfig /etc/rsyslog.d/*.conf $OmitLocalLogging on $IMJournalStateFile imjournal.state *.* @172.25.0.55:514 *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg :omusrmsg:* uucp,news.crit /var/log/spooler local7.* /var/log/boot.log
5.1.4 服務端重要配置
[root@foundation 2019-07-01]# grep -v "^#" /etc/rsyslog.conf | grep -v "^$" $ModLoad imuxsock # provides support for local system logging (e.g. via logger command) $ModLoad imjournal # provides access to the systemd journal $ModLoad imudp $UDPServerRun 514 $ModLoad imtcp $InputTCPServerRun 514 $template RemoteHost,"/var/log/rsyslog/%$YEAR%-%$MONTH%-%$DAY%/%FROMHOST-IP%.log" *.* ?RemoteHost & ~ $WorkDirectory /var/lib/rsyslog $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $IncludeConfig /etc/rsyslog.d/*.conf $OmitLocalLogging on $IMJournalStateFile imjournal.state *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg :omusrmsg:* uucp,news.crit /var/log/spooler local7.* /var/log/boot.log
5.2 rsyslog使用數據庫作為存儲介質
注意：客戶端配置和前面一致即可。
5.2.1 配置
服務端僅做下面的配置即可。
1 [root@foundation ~]# yum install rsyslog-mysql
使用腳本創建數據庫：
[root@foundation ~]# mysql -ursyslog -h127.0.0.1 -p </usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql Enter password:
為Rsyslog創建數據庫賬戶
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
重啟rsyslogd
1 systemctl restart rsyslog.service 2 systemctl enable rsyslog.service
5.2.2 測試
使用rsyslog用戶登錄數據庫后查看
部分截圖
5.2.3 附MySQL導入導出SQL文件
導出整個數據庫中的所有數據： 1、在linux命令行下輸入： mysqldump -u userName -p dabaseName > fileName.sql fileName.sql最好加上路徑名 導出數據庫中的某個表的數據： mysqldump -u userName -p dabaseName tableName > fileName.sql 導出整個數據庫中的所有的表結構 在linux命令行下輸入： mysqldump -u userName -p -d dabaseName > fileName.sql 注意：是加了-d 導出整個數據庫中某個表的表結構 在linux命令行下輸入： mysqldump -u userName -p -d dabaseName tableName > fileName.sql 注意：是加了-d 導入mysql方法1(測試好用) 進入linux命令命令行下： mysql -u root -p 回車 輸入密碼 mysql> use weifang mysql> source /home/user/data/fileName.sql 注意fileName.sql要有路徑名，例如：source /home/user/data/fileName.sql 導入mysql方法2(測試一次，導入數據后占空間異常大，還需驗證) 進入linux命令命令行下： mysql -uroot -p database < fileName.sql 注意fileName.sql要有路徑名
最后希望大家提意見、轉發、評論和交流！！！
