1. 本例中，主机server200-21为salt-master，其他主机为salt-minion
2. 【salt-master】
安装：
[root@server200-21 download]
# yum install salt-master
启动服务：
[root@server200-21 download]
# service salt-master start
Starting salt-master daemon: [ OK ]
防火墙放行端口：4505:4506
（接下来先跳转到第3步，配置一个minion）
列出salt-key：
salt-key -L
最初没有需要accept的key：
[root@server200-21 ~]
# salt-key -L
Accepted Keys:
Unaccepted Keys:
Rejected Keys:
有minion申请连接到master后：
[root@server200-21 ~]
# salt-key -L
Accepted Keys:
Unaccepted Keys:
test230
Rejected Keys:
可以accept所有被pending的key：
salt-key -A
也可以accept指定key
[root@server200-21 ~]
# salt-key -a test230
The following keys are going to be accepted:
Unaccepted Keys:
test230
Proceed? [n
/Y
] y
Key
for
minion test230 accepted.
附上【salt-key】常用命令
Actions:
-l ARG, --list=ARG List the public keys. The args
"pre"
,
"un"
, and
"unaccepted"
will list unaccepted
/unsigned
keys.
"acc"
or
"accepted"
will list accepted
/signed
keys.
"rej"
or
"rejected"
will list rejected keys. Finally,
"all"
will list all keys.
-L, --list-all List all public keys. (Deprecated: use
"--list all"
)
-a ACCEPT, --accept=ACCEPT
Accept the specified public key (use --include-all to
match rejected keys
in
addition to pending keys).
Globs are supported.
-A, --accept-all Accept all pending keys
-r REJECT, --reject=REJECT
Reject the specified public key (use --include-all to
match accepted keys
in
addition to pending keys).
Globs are supported.
-R, --reject-all Reject all pending keys
--include-all Include non-pending keys when accepting
/rejecting
-p PRINT, --print=PRINT
Print the specified public key
-P, --print-all Print all public keys
-d DELETE, --delete=DELETE
Delete the specified key. Globs are supported.
-D, --delete-all Delete all keys
-f FINGER, --finger=FINGER
Print the specified key's fingerprint
-F, --finger-all Print all keys' fingerprints
3. 【salt-minion】
安装：
[root@test230 download]
# yum install salt-minion
配置master和自己的
id
：
[root@test230 download]
# cat /etc/salt/minion |grep ^[^#]
master: 10.0.200.21
id
: test230
启动服务：
[root@test230 download]
# service salt-minion start
Starting salt-minion daemon: [ OK ]
注意：master的端口需要开放才能访问。
[root@test230 download]
# service salt-minion restart
Stopping salt-minion daemon: [FAILED]
Starting salt-minion daemon: [ OK ]
等待master接受minion的key
master已接受
4. 测试
[root@server200-21 ~]
# salt '*' test.ping
test230:
True
接下来，测试安装一个服务：
配置master：
[root@server200-21 ~]
# cat /etc/salt/master |grep -v ^$|grep -v ^#
file_roots:
base:
-
/srv/salt
[root@server200-21 ~]
# mkdir /srv/salt/
[root@server200-21 ~]
# cd /srv/salt/
[root@server200-21 salt]
# ls
servers.sls
top
.sls
[root@server200-21 salt]
# cat top.sls
base:
'*'
:
- servers
[root@server200-21 salt]
# cat servers.sls
dnsmasq:
pkg:
- installed
执行：
[root@server200-21 salt]
# salt '*' state.highstate
test230:
----------
ID: dnsmasq
Function: pkg.installed
Result: True
Comment: Package dnsmasq is already installed.
