CentOS7下Centreon的安装部署

1. Centreon的Packages方式安装（安装文档来源：docs.centreon.com）

Centreon provides RPM packages for its products through the Centreon Open Sources version available free of charge in our repository.
These packages have been successfully tested in CentOS 7.x environments.
After installating your server, consider updating your operating system via the command:

yum update

1.1. 安装前准备步骤

1.1.1 关闭SELinux

SELinux should be disabled. To do this, you have to edit the file /etc/selinux/config and replace enforcing by disabled, or by running the following command:

sed -i s/^SELINUX=.*$/SELINUX=disabled/ /etc/selinux/config

After system startup, perform a quick check of the SELinux status:

1. getenforce
Disabled

1.1.2. 配置或关闭firewall

Add firewall rules or disable the firewall by running the following commands:

1. systemctl stop firewalld
2. systemctl disable firewalld

1.1.3. 安装仓库（Install the repositories）

Redhat Software Collections repository

To install Centreon you will need to set up the official Software Collections repository supported by Redhat.
Install the Software Collections repository using this command:

yum install -y centos-release-scl

Centreon repository

To install Centreon software from the repository, you should first install the centreon-release package, which will provide the repository file.
Install the Centreon repository using this command:

yum install -y http://yum.centreon.com/standard/20.10/el7/stable/noarch/RPMS/centreon-release-20.10-2.el7.centos.noarch.rpm
