SaltStack iptables

yum install salt-master
chkconfig salt-master on
service salt-master start

cp /etc/salt/master{,.original}

yum install salt-minion
chkconfig salt-minion on

配置 master

			
cp /etc/salt/minion{,.original}
sed -i '12,12imaster: salt.example.org' /etc/salt/minion

cat >> /etc/hosts <<'EOF'

192.168.2.1    salt.example.org
EOF
			

service salt-minion start

-A INPUT -p tcp -m multiport --dports 4505,4506 -m state --state NEW -j ACCEPT

登陆master服务器，输入 salt-key 查看接入的 minion 客户端。

# salt-key
Accepted Keys:
Unaccepted Keys:
haproxy
Rejected Keys:

接受客户端 key

# salt-key -a haproxy
The following keys are going to be accepted:
Unaccepted Keys:
haproxy
Proceed? [n/Y] y
Key for minion haproxy accepted.

至此，master 与 minion 已经建立了信任关系

你可以运行下面命令测试你的 minion

salt '*' test.arg 1 "two" 3.1 txt="hello" wow='{a: 1, b: "hello"}'
salt '*' test.arg_repr 1 "two" 3.1 txt="hello" wow='{a: 1, b: "hello"}'
salt '*' test.collatz 3
salt '*' test.conf_test
salt '*' test.cross_test file.gid_to_group 0
salt '*' test.echo 'foo bar baz quo qux'
salt '*' test.fib 3
salt '*' test.get_opts
salt '*' test.kwarg num=1 txt="two" env='{a: 1, b: "hello"}'
salt '*' test.not_loaded
salt '*' test.outputter foobar
salt '*' test.ping
salt '*' test.provider service
salt '*' test.providers
salt '*' test.rand_sleep 60
salt '*' test.retcode 42
salt '*' test.sleep 20
salt '*' test.tty tty0 'This is a test'
salt '*' test.tty pts3 'This is a test'
salt '*' test.version
salt '*' test.versions_information
salt '*' test.versions_report

我通常只作ping测试

# salt '*' test.ping
haproxy:
    True

# salt '*' test.versions_information

单独测试某一节点

salt 'haproxy' test.ping

这里为你掩饰的是，将iptables文件推送到所有的服务器上。

# vim /srv/salt/top.sis

base:
  '*':
    - iptables

# vim /srv/salt/iptables.sls

/etc/sysconfig/iptables:
  file:
    - managed
    - source: salt://iptables
    - user: root
    - group: root
    - mode: 644
    - backup: minion

# vim /srv/salt/iptables

# Manual customization of this file is not recommended.

单独部署iptables

# salt '*' state.sls iptables

按照 top.sls 的设置执行

salt '*' state.highstate -v
