篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了老大说saltstack,本姑娘不敢不遵----saltstack安装相关的知识,希望对你有一定的参考价值。

我们的服务器,前前后后,左左右右,上上下下,屈手指脚趾算数,恰恰刚好,再差径我的数学课程也是语文补充传授的,本姑娘始终未懂老板为什么偏偏喜欢用saltstack。

道听途说,谁谁谁推荐忽悠上司,天没理,我就是想打个酱油。

人生无奈,要怪就怪本姑娘当初选择IT,苦不堪言,谁来谁知道,谁滚谁清楚。

逼上梁山,无可奈何花落去,天若有情天亦老,开始独自学习安装saltstack,本姑娘也是拼了的。

什么是saltstack,三言两语:批量。批量管理服务器信息,批量新增用户,批量安装软件,批量更新配置文件。

反正N多服务器时需要【批量】干嘛时,估计这贷能泒到场面中间溜达。

我的虚拟机信息:

[[email protected] ~]# cat /etc/centos-release 
CentOS release 6.5 (Final)
[[email protected] ~]# uname -r
2.6.32-431.el6.x86_64

狡黠地笑笑,本来想源码安装saltstack,哎,熟知一入豪门深似贱,从此无知似朋友。

各种奇葩问题都从我指缝流窜,还川流不息,当初还自诩什么风浪本小姐没见过,当你真正领教之后,便知:爱过方知情重,试过方知悔浓。

本姑娘果断拒绝源码安装,转向epel源安装saltstack。

Complete!

然后一切突然来的这么的猝不及防,没问题,安装成功,对于源码安装成功的自然牛逼哄哄,毕竟输掉心情,即使就算赢得掌声。

如果你想尝试,我信,甭提:伤心总是多余的。我唱歌给你听~~~~

服务端安装:

[[email protected] ~]# yum install salt.noarch salt-master.noarch  -y

客户端安装【也要先安装epel: yum install epel-release.noarch -y】

 

[[email protected] ~]# yum install salt.noarch salt-minion.noarch  -y

这干净利落,简值爱得不要不要的。

我的虚拟机是克隆的,虽然气质不俗,亦不至伤风雅,改改名称,稍微装饰一下hostname更漂亮一点。

服务端:
[[email protected] ~]# hostname
localhost.localdomain
[[email protected] ~]#  cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=salt.master.localdomain

客户端:
[[email protected] ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=salt.minion.localdomain


两端都得重启 network
[[email protected] ~]# service network restart
Shutting down interface eth0:  Device state: 3 (disconnected)
                                                           [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]

                                                           [  OK  ]

 

 先瞥一眼yum都安装啥东西,这里面的听说都是家常便饭,有空常喵喵。例如:重点配置文件:/etc/salt/master,什么乱五六遭都修改此配置,另外客户端也有一配置:/etc/salt/minion 就不罗列了。

[[email protected] salt]# rpm -ql salt-master
/etc/rc.d/init.d/salt-master
/etc/salt/master
/usr/bin/salt
/usr/bin/salt-cp
/usr/bin/salt-key
/usr/bin/salt-master
/usr/bin/salt-run
/usr/bin/salt-unity
/usr/share/man/man1/salt-cp.1.gz
/usr/share/man/man1/salt-key.1.gz
/usr/share/man/man1/salt-master.1.gz
/usr/share/man/man1/salt-run.1.gz
/usr/share/man/man1/salt-unity.1.gz
/usr/share/man/man7/salt.7.gz

此时只修改客户端的配置/etc/salt/minion,只改一项目,master配置为服务端的IP,这样差不多服务端与客户端就可以勾结一块,法律允许的话。

# Set the location of the salt master server. If the master server cannot be
# resolved, then the minion will fail to start.
master: 192.168.37.131

耐不住心情,掩不住的愉悦,服务端与客户端的服务启动

[[email protected] salt]# service salt-master start
Starting salt-master daemon:                               [  OK  ]
[[email protected] salt]# 
[[email protected] salt]# service salt-minion start
Starting salt-minion daemon:                               [  OK  ]
[[email protected] salt]# 

 心情淡定如浅水,眼睛幽蓝得深邃,结果扫描一遍后,差强人意,原来防火蔷惹的锅,本姑娘较真对这防火墙咬牙切齿,一问三不知,谁让我:防人之心我没有,唯有狠心说句:宝贝,白白!

[[email protected] salt]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

来个简单测试,缓解一下压力:

[[email protected] salt]# salt-key -A -y

这简单测试我也懒得释解,本姑娘都懂的,你若是不懂的话,甚至还好意思疑问的话,估计,哈哈。

经本小姐研究一翻,这saltstack好像似乎有哪么一丁点差不多人见人爱,车见车载的,可是我这吃喝拉撒睡的时间都快没了,呜呜。。。。
