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

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

填写组织详细信息。
Spacewalk已成功安装。
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 Resolving spacewalk.sunil.cc... 192.168.1.20 Connecting to spacewalk.sunil.cc|192.168.1.20|:80... connected.

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: INFO: Connected to https://spacewalk.sunil.cc/rpc/api as administrator spacecmd {SSM:0}> system_list centos6.sunil.cc centos7.sunil.cc 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" INFO: Connected to https://spacewalk.sunil.cc/rpc/api as administrator User: root Group: root Timeout: 600 seconds Start Time: 20170305T12:16:17 p Script Contents --------------- #!/bin/bash cat /etc/redhat-release Systems ------- centos6.sunil.cc INFO: Action ID: 33 INFO: Scheduled: 1 system(s) [root@spacewalk ~]#
要检查输出,您可以运行以下命令。
[root@spacewalk ~]# spacecmd schedule_getoutput 33 INFO: Connected to https://spacewalk.sunil.cc/rpc/api as administrator System: centos6.sunil.cc Start Time: 20170305T12:16:19 Stop Time: 20170305T12:16:19 Return Code: 0 Output ------ CentOS release 6.8 (Final) [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) Active: active (running) since Sun 2017-03-05 09:59:55 CET; 2h 21min ago Process: 3470 ExecStart=/usr/sbin/osa-dispatcher --pid-file /var/run/osa-dispatcher.pid (code=exited, status=0/SUCCESS) Process: 3469 ExecStartPre=/bin/rm -f /var/run/osa-dispatcher.pid (code=exited, status=0/SUCCESS) Main PID: 3474 (osa-dispatcher) CGroup: /system.slice/osa-dispatcher.service ??3474 /usr/bin/python -s /usr/sbin/osa-dispatcher --pid-file /var/run/osa-dispatcher.pid Mar 05 09:59:55 spacewalk.sunil.cc systemd[1]: Starting 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 [root@centos7test ~]# systemctl status osad ? osad.service - OSAD daemon Loaded: loaded (/usr/lib/systemd/system/osad.service; enabled; vendor preset: disabled) Active: active (running) since Sun 2017-03-05 13:54:46 CET; 26s ago Process: 18696 ExecStart=/usr/sbin/osad --pid-file /var/run/osad.pid (code=exited, status=0/SUCCESS) Main PID: 18697 (osad) CGroup: /system.slice/osad.service ??18697 /usr/bin/python -s /usr/sbin/osad --pid-file /var/run/osad.pid Mar 05 13:54:46 centos7test.sunil.cc systemd[1]: Starting OSAD daemon...

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 Using server name spacewalk.sunil.cc Config channels: Label Name ----- ---- motd-change motd [root@centos6 ~]# [root@centos6 ~]# rhncfg-client get Using server name spacewalk.sunil.cc Deploying /etc/motd [root@centos6 ~]# [root@centos6 ~]# ls -l /etc/motd -rw-r--r-- 1 root root 760 Mar 5 14:29 /etc/motd [root@centos6 ~]# cat /etc/motd ******************************************************************** * * * This system is for the use of authorized users only.
