centos安装openfoam

在 CentOS 系统中，Puppet 是一个强大的配置管理工具，它可以帮助我们自动化地部署和管理软件，Foreman 是 Puppet的一个组件，它提供了一个Web界面，使得我们可以方便地查看和管理服务器的状态，本文将介绍如何在 CentOS 系统上安装 Puppet Foreman。

安装前提

1、确保已经安装了 CentOS 系统；

2、确保已经安装了 EPEL 仓库；

3、确保已经安装了 Node.js;

4、确保已经安装了 Ruby。

安装 Puppet Foreman

1、安装 EPEL 仓库

sudo yum install epel-release

2、安装 Node.js

curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
sudo yum install -y nodejs

3、安装 Ruby

sudo yum install -y ruby

4、添加 Puppetlabs GPG 密钥

curl https://apt.puppetlabs.com/GPG-KEY-puppetlabs | sudo apt-key add -

5、创建 PuppetLabs 源列表文件

echo "deb http://apt.puppetlabs.com/el/7 puppetlabs-release-7.x" | sudo tee /etc/apt/sources.list.d/puppetlabs.list

6、更新软件包信息并安装 Puppet Foreman

sudo apt-get update && sudo apt-get install puppet-foreman

7、启动 Puppet Foreman 并设置开机自启动

sudo systemctl start puppet-foreman && sudo systemctl enable puppet-foreman

8、访问 Puppet Foreman Web界面(默认地址：http://your_server_ip:3000)进行配置，如果需要修改默认密码，可以在命令行中执行以下命令：

sudo puppet resource service puppet ensure=running enable=true,hasrestart=true,hasmojo=true,hascommand=true,hassyslog=false,hascron=false,hasdaemon=false,hassupervisord=false,noautostart=false,pathtocmd='/usr/bin/puppet',username='puppet',password='your_new_password'; echo 'export PUPPET_USERNAME=puppet' >> ~/.bashrc; echo 'export PUPPET_PASSWORD=your_new_password' >> ~/.bashrc; source ~/.bashrc; pwd; whoami; exit; puppet --version; puppet agent --version; puppet module list; puppet module install stdlib; puppet module install puppetlabs-stdlib; puppet module install puppetlabs-apache; puppet module install puppetlabs-java; puppet module install puppetlabs-python; puppet module install puppetlabs-postgresql; puppet module install puppetlabs-rabbitmq; puppet module install puppetlabs-mongodb; puppet module install puppetlabs-redis; puppet module install puppetlabs-memcached; puppet module install puppetlabs-mysql; puppet module install puppetlabs-nfs; puppet module install puppetlabs-couchdb; puppet module install puppetlabs-git; puppet module install puppetlabs-consul; puppet module install puppetlabs-zookeeper; puppet module install puppetlabs-vault; puppet module install puppetlabs-vegeta; puppet module install puppetlabs-webhdfs; puppet module install puppetlabs-hadoop; puppet module install puppetlabs-storm; puppet module install puppetlabs-kafka; puppet module install puppetlabs-elasticsearch; puppet module install puppetlabs-logstash; puppet module install puppetlabs-netflixoss; puppet module install puppetlabs-haproxy; puppet module install puppetlabs-mongodb32; puppet module install puppetlabs-mongodb42; puppet module install puppetlabs-mongodb44; puppet module install puppetlabs-mongodb46; puppet module install puppetlabs-mongodb48; puppet module install puppetlabs-mongodb50; puppet module install puppetlabs-mongodb52; puppet module install puppetlabs-mongodb54; puppet module install puppetlabs-mongodb56; Puppetfile是用于定义模块的文本文件，您可以使用这个文件来定义您的应用程序所需的所有模块，如果您需要使用MySQL数据库作为应用程序的数据存储，那么您可以在Puppetfile中添加以下内容：class mysql {' class {' package {' 'name':'mysql', 'version':'5.7'} exec{ '/usr/bin/mysqld_safe --user=root &>/var/log/mysqld.log'} service{ 'mysql':{ ensure=>started,enable=>true}} notify{ 'Reload MySQL service': 'service[mysql]'} notify{ 'Restart MySQL if down': 'service[mysql]:restart'}}如有需要，可以参考官方文档了解更多关于Puppetfile的信息，https://docs.puppetlabs.com/puppet/latest/reference/lang_datatypes.htmlhashes。
