一、安装mysql

# yum -y install mariadb-server
# systemctl enable --now mariadb && systemctl status mariadb
● mariadb.service - MariaDB 10.3 database server
   Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2021-12-25 03:56:37 EST; 2min 38s ago
     Docs: man:mysqld(8)

   Memory: 87.3M
   CGroup: /system.slice/mariadb.service
           └─31573 /usr/libexec/mysqld --basedir=/usr

二、安装rsyslog

# yum -y install rsyslog-mysql
#将sql脚本复制到数据库服务器
# scp /usr/share/doc/rsyslog/mysql-createDB.sql 10.0.0.28:/root/

三、配置mysql服务器

3.1 导入数据库

# mysql -uroot < mysql-createDB.sql
# mysql -e "show databases;"
+--------------------+
| Database           |
+--------------------+
| Syslog             |
| information_schema |
| mysql              |
| performance_schema |
+--------------------+

3.2 创建授权用户

# mysql -e "create user rsyslog@'10.0.0.%' identified by '123456';"
# mysql -e "grant all on Syslog.* to 'rsyslog'@'10.0.0.%';"
# mysql -e "select user,host from mysql.user;"
+---------+--------------+
| user    | host         |
+---------+--------------+
| rsyslog | 10.0.0.%     |
| root    | 127.0.0.1    |
| root    | ::1          |
| root    | localhost    |
| root    | mysql-server |
+---------+--------------+

四、配置rsyslog服务器

4.1 配置日志服务器将日志发送至指定数据库

[root@ rsyslog-server ~]#vim /etc/rsyslog.conf
####MODULES####    #在 MODULES 语言下面添加
module(load="ommysql")

#在RULES语句块下面添加
#### RULES ####
#facility.priority :ommysql:DBHOST,DBNAME,DBUSER, PASSWORD
*.info :ommysql:10.0.0.28,Syslog,rsyslog,123456

[root@ rsyslog-server ~]# systemctl restart rsyslog.service

4.2 测试

#在日志服务器上生成日志
# logger "this is a test log"

#在数据库上查询到上面的测试日志
$> mysql -e "select count(*) from Syslog.SystemEvents;"
+----------+
| count(*) |
+----------+
|     1907 |
+----------+

# 可以看到测试日记已经存到Mysql的Syslog库中
# mysql -e "select *  from  Syslog.SystemEvents\G" | grep -C10 "this is a test log"
   GenericFileName: NULL
          SystemID: NULL
*************************** 1904. row ***************************
                ID: 1904
        CustomerID: NULL
        ReceivedAt: 2021-12-25 17:25:29
DeviceReportedTime: 2021-12-25 17:25:29
          Facility: 1
          Priority: 5
          FromHost: reyslog
           Message: this is a test log	
        NTSeverity: NULL
        Importance: NULL
       EventSource: NULL
         EventUser: NULL
     EventCategory: NULL
           EventID: NULL
   EventBinaryData: NULL
      MaxAvailable: NULL
         CurrUsage: NULL
          MinUsage: NULL

五、部署配置LogAnalyzer

5.1 安装LogAnalyzer

# wget https://download.adiscon.com/loganalyzer/loganalyzer-4.1.10.tar.gz
# tar xvf loganalyzer-4.1.10.tar.gz
# mkdir /var/www/html/log
# mv loganalyzer-4.1.10/src/* /var/www/html/log

5.2 安装相关服务

# yum -y install httpd php-fpm php-mysqlnd php-gd
# systemctl enable --now httpd php-fpm && systemctl status httpd php-fpm

5.3 测试php

php是使用套接字和httpd通讯的，并非监听在9000端口。
需要监听在端口，修改配置文件/etc/php-fpm.d/www.conf，监听端修改为：listen = 127.0.0.1:9000

# cat > /var/www/html/info.php << EOF
<?php phpinfo() ?>
EOF

# 打开浏览器访问http://10.0.0.38/info.php，没问题继续下一步操作

六、基于 web 页面初始化LogAnalyzer

6.1 打开浏览器

访问http://10.0.0.38/log 实现初始化

6.2 提示缺失配置文件

# touch /var/www/html/log/config.php
# chmod 666 /var/www/html/log/config.php

6.3 重新访问

6.4 测试

[root@reyslog ~]# logger "this is a test log"
[root@reyslog ~]# logger "this is a newtest log
