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
[jpackage-generic]
name=JPackage generic
baseurl=http://vesta.informatik.rwth-aachen.de/ftp/pub/comp/Linux/jpackage/5.0/generic/free/
#mirrorlist=http://www.jpackage.org/mirrorlist.php?dist=generic&type=free&release=5.0
enabled=1
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
/usr/bin/spacewalk-setup-postgresql: line 100: isSUSE: command not found

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

如何在CentOS上安装Spacewalk

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

如何在CentOS上安装Spacewalk

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

如何在CentOS上安装Spacewalk

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

如何在CentOS上安装Spacewalk

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

2017-03-04 21:54:17 (630 MB/s) - /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT saved [5291/5291]

[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。

如何在CentOS上安装Spacewalk

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。

如何在CentOS上安装Spacewalk

单击远程命令，然后键入执行所需的命令。

如何在CentOS上安装Spacewalk

计划后，您可以转到计划选项卡并检查状态。

如何在CentOS上安装Spacewalk

单击主机以查看结果。

如何在CentOS上安装Spacewalk

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"

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)

[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
