如何在CentOS上安装Spacewalk

Spacewalk在防火墙后面管理Red Hat衍生发行版(例如Fedora,CentOS和Scientific Linux)的软件内容更新。这是RedHat satellite 5的开源版本。我们确实有RedHat satellite 6,开源版本是katello。我将在我的下一个教程中详细介绍如何配置它。当管理基础架构时,Spacewalk是一个非常强大的工具,它确实稳定且构建良好。

我将通过Spacewalk进行安装,并将向您详细介绍如何将其配置为可投入生产,以及我们可以使用的所有功能。我要进行嵌入式Postgres安装。

在本教程中,我将使用3台服务器:

  • 192.168.1.20 – spacewalk Server – centos 7
  • 192.168.1.21 – spacewalk client – centos 6
  • 192.168.1.22 – space walk client – centos 7

要求

最低安装的CentOS 7:

cat /etc/redhat-release

结果:

CentOS Linux release 7.3.1611(Core)

强制模式下的SELinux:

sestatus
SELinux status: enabled 
SELinuxfs mount: /sys/fs/selinux
SELinux rootdirectory: /etc/selinux 
Loaded policy name: targeted 
Current mode:enforcing 
Mode from config file: enforcing 
Policy MLS status: enabled
Policy deny_unknown status: allowed 
Max kernel policy version: 28
[root@spacewalk ~]#

添加主机条目/ etc / hosts

192.168.1.20 spacewalk.sunil.cc spacewalk

Spacewalk服务器的安装

安装Spacewalk CentOS存储库。

rpm -Uvh http://yum.spacewalkproject.org/2.6/RHEL/7/x86_64/spacewalk-repo-2.6-0.el7.noarch.rpm
cat > /etc/yum.repos.d/jpackage-generic.repo << EOF

gpgcheck=1
gpgkey=http://www.jpackage.org/jpackage.asc
EOF
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

为太空行走安装PostgreSQL:

yum install -y spacewalk-setup-postgresql spacewalk-postgresql

添加防火墙规则。

firewall-cmd --add-service=http --permanent; firewall-cmd --add-service=https --permanent; firewall-cmd --add-port=5222/tcp --permanent;firewall-cmd --add-port=5269/tcp --permanent;firewall-cmd --add-port=69 â??permanent; firewall-cmd --add-port=5222/udp --permanent;firewall-cmd --add-port=5269/udp --permanent

并重新加载防火墙。

firewall-cmd --reload

启用防火墙。

systemctl enable firewalld
systemctl restart firewalld

配置PostgreSQL服务器。

在这里,我给数据库名称是spacewalk,用户名是spacewalkuser,密码是spacewalkuser。

spacewalk-setup-postgresql create --db spacewalk --user spacewalkuser --password spacewalkuser
/usr/bin/spacewalk-setup-postgresql: line 87: isSUSE: command not found

配置用户Spacewalk

从浏览器http://192.168.1.20访问URL

填写组织详细信息。

在太空漫步中填写详细信息

Spacewalk已成功安装。

太空漫步开始

Spacewalk频道创建

点击频道->管理软件频道->创建频道

创建一个父频道-> centos6.8-parent

现在我们需要创建子渠道

频道->管理频道->创建频道

选择父频道为centos-6.8-parent

现在我们将为centos 6.8创建仓库

将仓库链接到我们之前创建的子频道

需要在centos 7中复制相同的步骤以创建通道。

现在我们需要从仓库中下载软件包。我们可以通过命令行或从仪表板进行操作。

命令行

从网络浏览器

您还可以在此页面中安排每天或每周进行同步以进行自动同步,也可以选择仅同步最新软件包

为Centos 6和centos 7主机创建激活密钥以使用Spacewalk服务器进行身份验证

转到系统->激活密钥->创建密钥

现在我们需要为centos 6创建密钥,在这里我将密钥用作centos-6并选择之前创建的centos-6.8-parent的父通道

对centos 7做同样的事情

您应该看到两个键,一个用于centos 6,另一个用于centos 7

客户端配置

在本章中,我将向您展示如何使用Spacewalk服务器安装和配置客户端。

Cento6-192.168.1.21

Cento7-192.168.1.22

配置yum客户端仓库

Centos 6

[ root @ centos6〜]#rpm -Uvh http://yum.spacewalkproject.org/2.6-client/RHEL/6/x86_64/spacewalk-client-repo-2.6-0.el6.noarch.rpm

Centos 7

[ root @ centos7〜]#rpm -Uvh http://yum.spacewalkproject.org/2.6-client/RHEL/7/x86_64/spacewalk-client-repo-2.6-0.el7.noarch.rpm

安装所需的软件包。

Centos 6

在centos6和centos7节点上安装epel repo和以下软件包。

启用epel仓库

[ root @ centos6〜] #yum 安装epel-release -y    
[root@centos6 ~]# yum install rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin osad rhncfg-actions rhncfg-management -y

向Spacewalk服务器注册

在连接Spacewalk服务器之前,我们需要从Spacewalk服务器下载ssl证书。

[root@centos6 ~]# wget -O /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT http://spacewalk.sunil.cc/pub/RHN-ORG-TRUSTED-SSL-CERT
--2017-03-04 21:54:16--  http://spacewalk.sunil.cc/pub/RHN-ORG-TRUSTED-SSL-CERT

[root@centos6 ~]#

现在,我们需要与我们前面创建的激活密钥注册,我们创造了1 centos6为centos6和1 centos7的centos7。

Centos 6

[root@centos6 ~]# rhnreg_ks --force --activationkey="1-centos6" --serverUrl=http://spacewalk.sunil.cc/XMLRPC --sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT --profilename=$HOSTNAME

Centos 7

[root@centos7 ~]# rhnreg_ks --force --activationkey="1-centos7" --serverUrl=http://spacewalk.sunil.cc/XMLRPC --sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT --profilename=$HOSTNAME

将配置文件与spacewalk同步,在centos6和centos7节点上运行它。

[root@centos7 ~]# rhn-profile-sync

这可用于从spacewalk运行远程命令和文件传输,以及使用spacewalk服务器的很酷的功能之一。

[root@centos6 ~]# chkconfig osad on
[root@centos6 ~]# service osad restart
Shutting down osad:                                        [  OK  ]
Starting osad:                                             [  OK  ]
[root@centos6 ~]# rhn-actions-control --enable-all
[root@centos6 ~]#
[root@centos7 ~]# systemctl enable osad
Created symlink from /etc/systemd/system/multi-user.target.wants/osad.service to /usr/lib/systemd/system/osad.service.
[root@centos7 ~]# systemctl restart osad
[root@centos7 ~]# rhn-actions-control --enable-all
[root@centos7 ~]#

现在我们可以进行个人资料同步。

[root@centos6 ~]# rhn-profile-sync
Updating package profile...
Updating hardware profile...
[root@centos6 ~]#
[root@centos7 ~]# rhn-profile-sync
Updating package profile...
Updating hardware profile...
[root@centos7 ~]#

现在可以在Spacewalk仪表板上进行检查。

通过Spacewalk运行远程命令并管理文件。

在本章中,我们将了解在运行远程命令和管理配置文件方面,Spacewalk有多么强大。

要运行“远程命令”,请登录到spacewalk仪表板并搜索需要在其中运行远程命令的主机。

单击远程命令,然后键入执行所需的命令。

计划后,您可以转到计划选项卡并检查状态。

单击主机以查看结果。

从spacewalk运行远程命令。

我们将需要安装spacecmd才能运行远程命令。

[ root @ spacewalk〜]#yum安装spacecmd -y

我们将首先使用ssm添加系统,然后才能登录,您可以使用与前端相同的凭据。

[root@spacewalk ~]# spacecmd
Welcome to spacecmd, a command-line interface to Spacewalk.

Type: 'help' for a list of commands
      'help ' for command-specific help
      'quit' to quit

Spacewalk Username: administrator
Spacewalk Password:

centos7test.sunil.cc
spacecmd {SSM:0}> ssm_add centos6.sunil.cc
spacecmd {SSM:1}> ssm_list
centos6.sunil.cc
spacecmd {SSM:1}> exit

创建一个名称任意的脚本,在这里我将其命名为ff.sh。

[root@spacewalk ~]# cat ff.sh
#!/bin/bash
cat /etc/redhat-release
[root@spacewalk ~]#

现在运行远程命令。

[root@spacewalk ~]# spacecmd -y system_runscript "ssm -f ff.sh"

[root@spacewalk ~]#

故障排除

如果您看到命令长时间处于暂挂状态,可以执行以下步骤来解决此问题。

确保osa-dispatcher在Spacewalk服务器上运行。

[root@spacewalk ~]# systemctl status osa-dispatcher
? osa-dispatcher.service - OSA Dispatcher daemon
   Loaded: loaded (/usr/lib/systemd/system/osa-dispatcher.service; enabled; vendor preset: disabled)

Mar 05 09:59:55 spacewalk.sunil.cc systemd[1]: Started OSA Dispatcher daemon.
[root@spacewalk ~]#

如果它没有运行,请重新启动Spacewalk服务。

    [ root @ spacewalk〜]#spacewalk-service重新启动

确保为5222打开了防火墙端口。

请在客户端执行以下步骤。

[root@centos7test ~]# systemctl stop osad
[root@centos7test ~]# rm -rf /etc/sysconfig/rhn/osad-auth.conf
[root@centos7test ~]# rhn_check -vvv
[root@centos7test ~]# systemctl start osad

通过Spacewalk部署文件。

在此示例中,我将更改centos 6服务器的motd。

我将首先创建一个配置通道。



创建具有以下内容的文件。

现在,我们需要订阅需要将其部署到的服务器的通道。


可以从客户端提取文件。

[root@centos6 ~]# rhncfg-client channels
