2.3.1 Centos 7安装

centos7系统的代理端IP地址为：192.168.1.101。接下来静态IP的设置的方法就不一一述说，参照wazuh管理端的centos7和Ubuntu18.04操作系统将相应的IP地址进行修改，重启网络服务。

添加wazuh yum安装仓库

# rpm --import https://packages.wazuh.com/key/GPG-KEY-WAZUH
# cat > /etc/yum.repos.d/wazuh.repo << EOF
[wazuh]
gpgcheck=1
gpgkey=https://packages.wazuh.com/key/GPG-KEY-WAZUH
enabled=1
name=EL-$releasever - Wazuh
baseurl=https://packages.wazuh.com/4.x/yum/
protect=1
EOF

使用yum命令安装wazuh代理端。

或者使用如下直链进行下载到本地安装。

https://packages.wazuh.com/4.x/yum/wazuh-agent-4.1.5-1.x86_64.rpm

rpm包安装

[root@wazuh-centos-agent opt]# rpm -ivh wazuh-agent-4.1.5-1.x86_64.rpm

设置服务自启动和服务启动

[root@wazuh-centos-agent opt]# systemctl enable wazuh-agent
Created symlink from /etc/systemd/system/multi-user.target.wants/wazuh-agent.service to /usr/lib/systemd/system/wazuh-agent.service.
[root@wazuh-centos-agent opt]# systemctl start wazuh-agent
Job for wazuh-agent.service failed because the control process exited with error code. See "systemctl status wazuh-agent.service" and "journalctl -xe" for details.

发现了代理端启动错误，查看错误信息（ Invalid server address found: 'MANAGER_IP'），解决这个错误只需**设置管理端IP地址，**后面章节再说明，现在暂时放下错误。

[root@wazuh-centos-agent opt]# systemctl status wazuh-agent
