1.selinux

[root@master init]# cd selinux/
[root@master selinux]# ls
files  main.sls
[root@master selinux]# cat main.sls 
/etc/selinux/config:
  file.managed:
    - source: salt://init/selinux/files/config
    - user: root
    - group: root
    - mode: '0644'
    
'setenforce 0':
  cmd.run
[root@master selinux]# cat files/config 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2.防火墙

[root@master firewalld]# cat main.sls 
firewalld.service:
  service.dead:
    - enable: false

3.chrony时间同步

[root@master chrony]# cat files/chrony.conf 
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
pool time1.aliyun.com iburst		 #修改时间同步服务器地址

# Record the rate at which the system clock gains/losses time.
driftfile /var/lib/chrony/drift
.......
[root@master chrony]# cat main.sls 
include:
  - init.yum.main
chrony:
