环境：CentOS7.6 ossec 2.8.3
1、安装所需要的包
[root@warship src]# yum install iptables-services tcpdump lrzsz gcc gcc-c++ vim wget lrzsz ntpdate sysstat dstat wget unzip httpd php php-mysql mariadb mariadb-server git
2、解压ossec，进入其中的src目录
[root@warship src]# make setdb
Error: PostgreSQL client libraries not installed.
Error: DB libraries not installed.
[root@warship src]# yum -y install mysql-devel
[root@warship src]# make setdb
Error: PostgreSQL client libraries not installed.
Info: Compiled with MySQL support.
cd …/
./install.sh
依次选择语言，smtp服务器，邮箱地址，最后显示
- 系统类型是 Redhat Linux.
- 修改启动脚本使 OSSEC HIDS 在系统启动时自动运行
- 已正确完成系统配置.
- 要启动 OSSEC HIDS:
/var/ossec/bin/ossec-control start
- 要停止 OSSEC HIDS:
/var/ossec/bin/ossec-control stop
- 要查看或修改系统配置,请编辑 /var/ossec/etc/ossec.conf
感谢使用 OSSEC HIDS.

配置mariadb
[root@warship ossec-hids-2.8.3]# mysql -uroot
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 2

[root@warship ossec-hids-2.8.3]# mysql -uossec -possec -D ossec < src/os_dbd/mysql.schema
[root@warship ossec-hids-2.8.3]# vim /var/ossec/etc/ossec.conf
在remote项设置监控的客户端服务器的地址范围
<remote>
<connection>syslog</connection>
<allowed-ips>192.168.238.0/24</allowed-ips>
</remote>
在最后添加
<ossec_config>
<database_output>
localhost
ossec
ossec
ossec
mysql
</database_output>
</ossec_config>
[root@warship ossec-hids-2.8.3]# /var/ossec/bin/ossec-control restart
ossec-monitord not running …
ossec-logcollector not running …
