很久之前,用过一段时间的Puppet,也就是简单用了用,后来慢慢就丢了,然后就去搞mysql的一些东西了,或许,很多事情就是注定的,以为再来不会用它了的时候,任务来了,说要继续研究这玩意,后面遇到一个牛X的同事,说用SaltStack比较好,而且他已经用这个做了不少实际游泳的案例了,他说,Puppet注重于最终状态,SaltStack注重于实时命令的运行,SaltStack=Puppet+Func,且SaltStack还是使用Python开发的,入手以及后续的功能自定义开发都是非常方便的。于是乎,就看看咯.

1. 安装SaltStack Master
[1] 配置本地YUM源
[root@DemoServer ~]# cat /etc/yum.repos.d/rhel-source.repo[rhel]name=rhelbaseurl=http://192.168.150.3/rhel6.3core/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[3] 开启YUM缓存,保存安装包
[root@DemoServer ~]# cat /etc/yum.conf [main]cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 修改为 keepcache=1debuglevel=2logfile=/var/log/yum.logexactarch=1obsoletes=1gpgcheck=1plugins=1installonly_limit=3
[4] 安装SaltStack Master 软件包
[root@DemoServer ~]# yum install python-jinja2-2.2.1-1.el6.x86_64.rpm salt-master salt-minion -y //本节点即作为Master,也作为Minion使用
[5] 保存所有依赖包,用于离线安装
[root@DemoServer packages]# ll /var/cache/yum/x86_64/6Server/epel/packagestotal 3356-rw-r--r--. 1 root root 52880 May 19 2010 libyaml-0.1.3-1.el6.x86_64.rpm-rw-r--r--. 1 root root 169348 Dec 26 2012 openpgm-5.1.118-3.el6.x86_64.rpm-rw-r--r--. 1 root root 29556 Jun 2 2013 python-msgpack-0.1.13-3.el6.x86_64.rpm-rw-r--r--. 1 root root 433896 Dec 15 2012 python-zmq-2.2.0.1-1.el6.x86_64.rpm-rw-r--r--. 1 root root 161120 Apr 28 2012 PyYAML-3.10-3.el6.x86_64.rpm-rw-r--r--. 1 root root 2156412 Nov 20 22:46 salt-0.17.2-2.el6.noarch.rpm-rw-r--r--. 1 root root 32124 Nov 20 22:46 salt-master-0.17.2-2.el6.noarch.rpm-rw-r--r--. 1 root root 20956 Nov 20 22:46 salt-minion-0.17.2-2.el6.noarch.rpm-rw-r--r--. 1 root root 19292 Aug 31 2011 sshpass-1.05-1.el6.x86_64.rpm-rw-r--r--. 1 root root 341724 Sep 22 02:18 zeromq3-3.2.4-1.el6.x86_64.rpm

[6] 制作SaltStack安装YUM源
[root@DemoServer ~]# mv saltstack0.17.4 /var/www/html/saltstack/[root@DemoServer ~]# yum install createrepo -y[root@DemoServer ~]# createrepo -p -d -o /var/www/html/saltstack/ \> /var/www/html/saltstack/12/12 - salt-minion-0.17.2-2.el6.noarch.rpm Saving Primary metadataSaving file lists metadataSaving other metadataGenerating sqlite DBsSqlite DBs complete
[7] 启动httpd服务
[root@DemoServer ~]# service httpd start
[8] 安装oracle节点的salt-minion
(1) 配置YUM源
[root@oracle ~]# cat /etc/yum.repos.d/rhel-source.repo[rhel]name=rhelbaseurl=http://192.168.150.3/rhel6.3core/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release[saltstack]name=saltstackbaseurl=http://192.168.153.38/saltstackenabled=1gpgcheck=0
(2) 安装salt-minion 软件包
[root@oracle ~]# yum install salt-minion -y
2. 启动服务
[root@DemoServer ~]# iptables -F ; service iptables save ; service iptables restart //清空所有IPTABLES规则,或者开放4505与4506端口[root@DemoServer ~]# setenforce 0 //手动设置SELINUX状态[root@DemoServer ~]# sed -i 's/enforcing/disabled/g' /etc/sysconfig/selinux //修改SELINUX状态为disabled,重启生效[root@DemoServer ~]# grep 'SELINUX=' /etc/sysconfig/selinux# SELINUX= can take one of these three values:SELINUX=disabled[root@DemoServer ~]# service salt-master start //启动salt-master[root@DemoServer ~]# chkconfig salt-master on //设置salt-master开机启动[root@DemoServer ~]# service salt-minion start //启动salt-minion[root@DemoServer ~]# chkconfig salt-minion on //设置salt-minion开机启动[root@DemoServer ~]# netstat -nltup |grep python //查看端口是否被监听tcp 0 0 192.168.153.38:4505 0.0.0.0:* LISTEN 882/python tcp 0 0 192.168.153.38:4506 0.0.0.0:* LISTEN 874/python
oracle节点上面同样启动
[root@oracle ~]# service salt-minion start //启动salt-minion服务[root@oracle ~]# chkconfig salt-minion on //设为开机启动
3. 修改配置文件
Master:[root@DemoServer ~]# cat /etc/salt/master |grep -v '#' |grep interfaceinterface: 192.168.153.38 //修改监听IP[root@DemoServer ~]# service salt-master restart //重启salt-master服务两个 Minion:[root@DemoServer ~]# cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.153.38DemoServer[root@DemoServer ~]# cat /etc/salt/minion |grep -v '#'|grep mastermaster: DemoServer //指定master的可解析的主机名或者IP地址[root@DemoServer ~]# service salt-minion restart //重启 salt-minion 服务[root@oracle ~]# cat /etc/salt/minion |grep -v '#' |grep mastermaster: 192.168.153.38[root@oracle ~]# service salt-minion restart //重启 salt-minion 服务
4. 密钥验证
[root@DemoServer ~]# salt-key -L //列出所有请求keyAccepted Keys:Unaccepted Keys:DemoServer == 本机oracle ==新主机,主机名为oracle IP为192.168.153.37Rejected Keys:【 上面识别到的id 默认取客户端的主机名的FQDN值,如果在客户端的/etc/salt/minion_id中进行修改,则会显示自定义的id值 】[root@DemoServer ~]# salt-key -a DemoServer //批准DemoServerThe following keys are going to be accepted:Unaccepted Keys:DemoServerProceed? [n/Y] yKey for minion DemoServer accepted.[root@DemoServer ~]# salt-key -LAccepted Keys:DemoServerUnaccepted Keys:oracleRejected Keys:[root@DemoServer ~]# salt-key -A //批准接受全部The following keys are going to be accepted:Unaccepted Keys:oracleProceed? [n/Y] yKey for minion oracle accepted.[root@DemoServer ~]# salt-key -L //再次查看,全部被接受Accepted Keys:DemoServeroracleUnaccepted Keys:Rejected Keys:
5. 简单命令尝试
[root@DemoServer ~]# salt oracle test.pingoracle: True[root@DemoServer ~]# salt '*' test.pingDemoServer: Trueoracle: True或者[root@DemoServer ~]# salt -L 'oracle153_37,DemoServer' test.pingoracle153_37: TrueDemoServer: TrueGrains 类似于Puppet中的facter[root@DemoServer ~]# salt -G 'cpuarch:x86_64' grains.item num_cpusDemoServer: num_cpus: 4oracle153_37: num_cpus: 4[root@DemoServer ~]# salt '*' grains.ls //查看有哪些参数可以显示[root@DemoServer ~]# salt '*' grains.items //列出所有参数的条目,item复数 //列出具体的参数值,item单数[root@DemoServer ~]# salt '*' grains.item osDemoServer: os: RedHatoracle153_37: os: RedHat
昨天对SaltStack的探讨就这些,记录下来,再深究。
