SaltStack(四) 配置管理
一、配置管理
Salt使用State模块文件进行配置管理，使用YAML编写，以.sls结尾，如果进行配置管理首先需要再Master的配置文件中指定“file roots”的选项，Salt支持的环境的配置，比如开发环节、测试环境、生产环境，但是base环境时必须的，而且base环境必须包含入口文件top.sls
第一步：设置file_roots
修改Master配置文件，指定Flie_roots [root@salt-server ~]# vim /etc/salt/master file_roots: base: - /srv/salt/ 创建相应的目录 [root@salt-server ~]# mkdir /srv/salt/ -p 重启Salt_Master [root@salt-server ~]# /etc/init.d/salt-master restart Stopping salt-master daemon: [确定] Starting salt-master daemon: [确定]
第二步：设置top.sls
在top.sls入口文件设置环境(如生产、开发、测试对应不同的minion和模块)
[root@salt-server ~]# cat /srv/salt/top.sls
base:
‘*‘:
- apache
解释：所有的Minion均执行base目录下的init模块下的pkg-int.sls，我们可以把很多的sls放在一个目录中，方便管理，在top.sls只需要指定目录结构即可。
第三步：编写状态文件
[root@salt-server ~]# cat /srv/salt/apache.sls
apache-install:
pkg.installed:
- names:
- httpd
- httpd-devel
apache-service:
service.running:
- enable: True
- reload: True
第四步：执行状态
[root@salt-server ~]# salt ‘*‘ state.highstate
salt-client:

Summary

Succeeded: 2 (changed=2)
Failed: 1

Total states run: 3
根据上面的设置，执行完状态后。Salt会检查Minion上是否有上面编写的三个软件包。如果没有就会自动使用Yum安装上。
启动httpd服务
[root@salt-server ~]# salt ‘*‘ cmd.run ‘/etc/init.d/httpd start‘
salt-client:
Starting httpd: httpd: apr_sockaddr_info_get() failed for salt-client
httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName

第五步：操作练习
下面是我生产安装Haproxy的案例，使用的源码，你参考下。
haproxy-install:
file.managed:
- name: /usr/local/src/haproxy-1.5.3.tar.gz
- source: salt://haproxy/files/haproxy-1.5.3.tar.gz
- mode: 755
- user: root
- group: root
cmd.run:
- name: cd /usr/local/src && tar zxf haproxy-1.5.3.tar.gz && cd haproxy-1.5.3 && make TARGET=linux26 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy
- unless: test -d /usr/local/haproxy
- require:
- file: haproxy-install
/etc/init.d/haproxy:
file.managed:
- source: salt://haproxy/files/haproxy.init
- mode: 755
- user: root
- group: root
- require:
- cmd: haproxy-install
net.ipv4.ip_nonlocal_bind:
sysctl.present:
- value: 1
haproxy-config-dir:
file.directory:
- name: /etc/haproxy
- mode: 755
- user: root
- group: root
haproxy-init:
cmd.run:
- name: chkconfig --add haproxy
- unless: chkconfig --list | grep haproxy
- require:
- file: /etc/init.d/haproxy
