salt语法：YAML
规则一：缩进
两个空格组成
不要使用tab键
规则二：冒号
他的结果是以字典的方式
以冒号结尾和路径不需要加冒号
以冒号结尾
规则三：短横线线
表示是一种列表关系（字典中的列表）
短横线后加空格

执行模块 Pillar
=======================================================
第一部分：系统的初始化模块
[root@linux-node1 base]# vim /etc/salt/master
file_roots:
base:
- /srv/salt/base
test:
- /srv/salt/test
prod:
- /srv/salt/prod
1、dns解析
[root@linux-node1 base]# mv * /tmp
[root@linux-node1 base]# mkdir init
[root@linux-node1 base]# cp /tmp/dns.sls init/
[root@linux-node1 base]# cat init/dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://init/files/resolv.conf
- user: root
- group: root
- mode: 644
[root@linux-node1 base]# mkdir init/files
[root@linux-node1 base]# cp /etc/resolv.conf init/files/
2、让history记住时间
使用file模块的append追加方式
[root@linux-node1 init]# vim history.sls
[root@linux-node1 init]# cat history.sls
/etc/profile:
file.append:
- text:
- export HISTTIMEFORMAT="%F %T `whoami` "
3、历史记录
[root@linux-node1 init]# cat audit.sls
/etc/bashrc:
file.append:
- text:
- export PROMPT_COMMAND='{ msg=$(history 1 | { read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg";}'
4、内核参数调优
使用sysctl.present:模块修改
[root@linux-node1 init]# cat sysctl.sls
vm.swappiness:
sysctl.present:
- value: 0
net.ipv4.ip_local_port_range:
sysctl.present:
- value: 10000 65000
fs.file-max:
sysctl.present:
- value: 100000
--------------------------------
此模块找/proc/sys下找东西，点分隔
/proc/sys/net/ipv4/ip_local_port_range
5、把上面四个包括进来
[root@linux-node1 init]# cat env_init.sls
include:
- init.dns
- init.history
- init.audit
- init.sysctl
[root@linux-node1 base]# cat /srv/salt/base/top.sls
base:
'*':
- init.env_init
测试一下
[root@linux-node1 init]# salt '*' state.highstate test=TRUE
2：功能模块
[root@linux-node1 ~]# mkdir /srv/salt/prod/pkg -p
[root@linux-node1 ~]# mkdir /srv/salt/prod/haproxy/files -p
[root@linux-node1 ~]# cd /srv/salt/prod/pkg/
[root@linux-node1 pkg]# vim pkg-init.sls
pkg-init:
pkg.installed:
- names:
- gcc
- gcc-c++
- glibc
- make
- autoconf
- openssl
- openssl-devel
[root@linux-node1 files]# cd /srv/salt/prod/haproxy/files
[root@linux-node1 init]# cd /srv/salt/prod/haproxy/files/
