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.

[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 metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite 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=rhel
baseurl=http://192.168.150.3/rhel6.3core/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[saltstack]
name=saltstack
baseurl=http://192.168.153.38/saltstack
enabled=1
gpgcheck=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 interface
interface: 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/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.153.38DemoServer
[root@DemoServer ~]# cat /etc/salt/minion |grep -v '#'|grep master
master: 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 master
master: 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key
Accepted Keys:
Unaccepted Keys:
DemoServer == 本机
oracle ==新主机,主机名为oracle IP为192.168.153.37
Rejected 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DemoServer
The following keys are going to be accepted:
Unaccepted Keys:
DemoServer
Proceed? [n/Y] y
Key for minion DemoServer accepted.
[root@DemoServer ~]# salt-key -L
Accepted Keys:
DemoServer
Unaccepted Keys:
oracle
Rejected Keys:
[root@DemoServer ~]# salt-key -A //批准接受全部
The following keys are going to be accepted:
Unaccepted Keys:
oracle
Proceed? [n/Y] y
Key for minion oracle accepted.
[root@DemoServer ~]# salt-key -L //再次查看,全部被接受
Accepted Keys:
DemoServer
oracle
Unaccepted Keys:
Rejected Keys:
5. 简单命令尝试
[root@DemoServer ~]# salt oracle test.ping
oracle:
True
[root@DemoServer ~]# salt '*' test.ping
DemoServer:
True
oracle:
True
或者
[root@DemoServer ~]# salt -L 'oracle153_37,DemoServer' test.ping
oracle153_37:
True
DemoServer:
True
Grains 类似于Puppet中的facter
[root@DemoServer ~]# salt -G 'cpuarch:x86_64' grains.item num_cpus
DemoServer:
num_cpus: 4
oracle153_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 os
DemoServer:
os: RedHat
oracle153_37:
os: RedHat
昨天对SaltStack的探讨就这些,记录下来,再深究。 |
