Chef是领先的开源持续基础架构和应用程序自动化工具，可带我们从开发到生产的所有过程。我们之前的指南涵盖了在Ubuntu 18.04 LTS上安装Chef Server。
本指南将重点介绍已安装的独立Chef Server配置的升级。尝试在CentOS 7机器上安装Chef自动化服务器方面做一个指导。
升级Chef服务器
请按照下面的步骤将Chef服务器升级到最新版本。
备份Chef Server数据
运行以下命令以确保所有服务均处于正常状态并备份所有Chef数据。
$chef-server-ctl reconfigure
备份数据：
# chef-server-ctl backup --yes Locating rsync.. /bin/rsync Starting Chef Server backup Bringing down the Chef Server ok: down: bookshelf: 1s, normally up ok: down: nginx: 0s, normally up ok: down: oc_bifrost: 0s, normally up ok: down: oc_id: 0s, normally up ok: down: opscode-chef-mover: 302s, normally up ok: down: opscode-erchef: 0s, normally up ok: down: opscode-expander: 1s, normally up ok: down: opscode-solr4: 0s, normally up ok: down: rabbitmq: 0s, normally up ok: down: redis_lb: 0s, normally up Dumping Postgresql database to /tmp/chef_backup20161030-11018-1r60p82/chef_backup-2016-10-30-14-44-09.sql could not change directory to "/tmp/d20161030-11018-1jnkroq": Permission denied ok: down: postgresql: 0s, normally up Writing backup manifest Creating backup tar包 /opt/opscode/embedded/lib/ruby/gems/2.5.0/gems/mixlib-shellout-2.3.2/lib/mixlib/shellout/unix.rb:185: warning: conflicting chdir during another chdir block tar: Removing leading `/' from member names Bringing up the Chef Server ok: run: bookshelf: (pid 11293) 0s ok: run: nginx: (pid 11372) 1s ok: run: oc_bifrost: (pid 11386) 1s ok: run: oc_id: (pid 11467) 0s ok: run: opscode-chef-mover: (pid 11482) 0s ok: run: opscode-erchef: (pid 11559) 0s ok: run: opscode-expander: (pid 11911) 0s ok: run: opscode-solr4: (pid 12052) 0s ok: run: postgresql: (pid 12090) 0s ok: run: rabbitmq: (pid 11561) 13s ok: run: redis_lb: (pid 12357) 1s Exporting tar包 to /var/opt/chef-backup Cleaning up /tmp/chef_backup20161030-11018-1r60p82 Backup Complete!
确认备份文件
# ls /var/opt/chef-backup/ chef-backup-2016-10-30-14-44-09.tgz
下载和升级Chef Server
从官方下载页面下载最新版本的Chef服务器。以下示例下载适用于CentOS 7的最新版Chef。
Ubuntu 18.04：
sudo apt update sudo apt -y install wget wget https://packages.chef.io/files/stable/chef-server/13.2.0/ubuntu/18.04/chef-server-core_13.2.0-1_amd64.deb
CentOS 7：
sudo dnf -y wget wget https://packages.chef.io/files/stable/chef-workstation/20.7.96/el/7/chef-workstation-20.7.96-1.el7.x86_64.rpm
下载软件包后，请使用分发软件包管理器进行安装。
sudo yum localinstall <package.rpm> -- Example -- sudo yum -y localinstall chef-workstation-20.7.96-1.el7.x86_64.rpm
对于Ubuntu，请使用：
sudo dpkg -i <package.deb> --- Example -- sudo apt install ./chef-server-core_13.2.0-1_amd64.deb
输出示例：
Running transaction Updating : chef-server-core-12.18.14-1.el7.x86_64 [###################################################### ] 1/ Updating : chef-server-core-12.18.14-1.el7.x86_64 [####################################################### ] 1/ Updating : chef-server-core-12.18.14-1.el7.x86_64 [######################################################## ] 1/ Upda Updating : chef-server-core-12.18.14-1.el7.x86_64 1/2 You have upgraded Chef Server! ...... For detailed upgrade instructions please see: https://docs.chef.io/upgrade_server.html Cleanup : chef-server-core-12.17.33-1.el7.x86_64 2/2 warning: file /opt/opscode/embedded/service/oc_id/log/development.log: remove failed: No such file or directory Verifying : chef-server-core-12.18.14-1.el7.x86_64 1/2 Verifying : chef-server-core-12.17.33-1.el7.x86_64 Updated: chef-server-core.x86_64 0:12.18.14-1.el7 Complete! 2/2
升级过程的下一步是运行：
$sudo chef-server-ctl upgrade
升级命令完成后，Chef服务将保持关闭状态。使它们重新运行：
$sudo sudo chef-server-ctl start ok: run: bookshelf: (pid 14176) 1s ok: run: nginx: (pid 14233) 0s ok: run: oc_bifrost: (pid 14255) 1s ok: run: oc_id: (pid 14289) 0s ok: run: opscode-chef-mover: (pid 14332) 0s ok: run: opscode-erchef: (pid 14335) 1s ok: run: opscode-expander: (pid 14475) 0s ok: run: opscode-solr4: (pid 14705) 0s ok: run: postgresql: (pid 14145) 189s ok: run: rabbitmq: (pid 14337) 1s ok: run: redis_lb: (pid 15079) 1s
最后，删除内部服务使用的配置文件，日志，目录，用户等，这些配置文件已从此版本的Chef Server中删除：
$sudo chef-server-ctl cleanup
我们可以添加--no-op选项，以查看此命令将删除的内容。
