前面使用了插件,让Minnion的数据写到数据库里。
现在让master上的数据直接写在文件里。
返回的数据在这里/var/cache/salt/master/jobs 是他自己的保存方式。
安装 MySQL-python
[root@salt-node4 ~]# yum -y install MySQL-python
salt库里的相关的建表语句请看salt一第一部分总结笔记
mysql.host: ‘127.0.0.1‘
mysql.user: ‘salt‘
mysql.pass: ‘salt@pw‘
mysql.db: ‘salt‘
mysql.port: 3306
重启master服务,让配置文件生效。
systemctl restart salt-master
3、测试。
[root@salt-node4 /srv]# mysql -usalt -psalt@pw
...
MariaDB [(none)]> select * from salt.salt_returns;
...

查看job cache里的数据
salt-run jobs.list_jobs
查看之前执行job的返回内容
salt-run jobs.lookup_jid jid号

查看minion的状态
[root@salt-node4 /srv]# salt-run manage.status
down:
up:
- test-node3.damaicha.org-203
- salt-node4.damaicha.org-204
查看正常连接的minion
[root@salt-node4 /srv]# salt-run manage.up
- test-node3.damaicha.org-203
- salt-node4.damaicha.org-204
查看down掉的minion
[root@salt-node4 /srv]# salt-run manage.down
查看minion的版本
[root@salt-node4 /srv]# salt-run manage.versions
Master:
2016.11.3
Up to date:
----------
salt-node4.damaicha.org-204:
2016.11.3
test-node3.damaicha.org-203:

files_roots pillar_roots 和master的一样,区别在预不从master获取数据,改成了从本地。
1 修改minion的配置文件。
[root@test-node3 ~]# vim /etc/salt/minion
..
530 file_client: local
..
[root@test-node3 ~]# systemctl restart salt-minion
2 测试
[root@test-node3 ~]# salt-call test.ping
local:
True
需要注意的事项。
<br/>keys: master minion<br/>file_roots里的所有文件<br/>pillar_root <br/>
####2 minion的配置。
- 10.0.0.203
- 10.0.0.204
发布任务:将先生要干一件事,他将要做的事情传给sydic(小秘),sydic再将要做的事情给陈浩南,陈浩南收到信息后再将事情指派给下面的小弟去做。
返回数据: 小弟干完事情后,将结果反馈给陈浩南,此时小秘(sydic)和陈浩南在一块,小秘听到后将消息转给蒋先生(不需要陈浩南反馈)
多机房
注意:syndic的file_roots pilar_roots必须和saltmaster的保持高度一致。
10.0.0.204 saltmaster+syndic minion
10.0.0.203 saltmaster 将先生
[root@salt-node4 ~]# yum -y install salt-syndic
[root@salt-node4 ~]# vim /etc/salt/maste
...
865 syndic_master: 10.0.0.203
...
[root@salt-node4 ~]# systemctl restart salt-master
[root@salt-node4 ~]# systemctl start salt-syndic
[root@test-node3 ~]# vim /etc/salt/master
...
857 order_masters: True
...
[root@test-node3 ~]# systemctl restart salt-master
[root@test-node3 ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
salt-node4.damaicha.org-204
Proceed? [n/Y] y
Key for minion salt-node
测试
[root@test-node3 ~]# salt ‘*‘ test.ping
salt-node4.damaicha.org-204:
True
test-node3.damaicha.org-203:
True
##4 saltstack-SSH
[root@salt-node4 ~]# yum -y install salt-ssh
[root@salt-node4 ~]# vim /etc/salt/roster
#添加如下:
test-node3.damaicha.org-203:
host: 10.0.0.204
user: root
passwd: 123..abc
port: 52113
salt-node4.damaicha.org-204:
host: 10.0.0.203
user: root
passwd: 123..abc
port: 52113
# 执行相当于c/s模式时的cmd.run (第一次使用时,这么玩。)
[root@salt-node4 ~]# salt-ssh ‘*‘ -r ‘ifconfig‘ -i
# 执行高级状态
[root@salt-node4 ~]# salt-ssh ‘*‘ state.highstate
拓展
拓展:
关闭ssh,key更换时提示的错误信息。
cd ~/.ssh
echo StricHostKeyChecking no >config
配置步骤
https://www.unixhot.com/docs/saltstack/ref/netapi/all/salt.netapi.rest_cherrypy.html#a-rest-api-for-salt
# 新建本地用户,后面调用api的时候会用到
[root@salt-node4 ~]# useradd -M -s /sbin/nologin saltapi
[root@salt-node4 ~]# echo ‘saltapi‘|passwd --stdin saltapi
# 本机产生https证书
[root@salt-node4 ~]# cd /etc/pki/tls/certs/
[root@salt-node4 /etc/pki/tls/certs]# make testcert 密码123123 然后一路回车
[root@salt-node4 /etc/pki/tls/certs]# cd /etc/pki/tls/private/
[root@salt-node4 /etc/pki/tls/private]# openssl rsa -in localhost.key -out salt_nopass.key 密码是123123
[root@salt-node4 /etc/pki/tls/private]# ls
localhost.key salt_nopass.key
[root@salt-node4 ~]# yum -y install python-pip salt-api
[root@salt-node4 ~]# pip install --upgrade pip
[root@salt-node4 ~]# pip install CherryPy==3.2.6 ``# ps: 如果不能安装这个版本就用yum来进行安装 yum install python-cherry*``
我遇到的梗:如果salt-api启动报错,记得看日志。如果是cherrypy的问题,就重装pip install CherryPy
拓展:
[root@salt-node4 ~]# vim .pip/pip.conf
#更新pip源为淘宝的:
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
[root@salt-node4 ~]# vim /etc/salt/master
...
12 default_include: master.d/*.conf
...
[root@salt-node4 ~]# cd /etc/salt/master.d/
[root@salt-node4 /etc/salt/master.d]# vim api.conf
rest_cherrypy:
host: 10.0.0.204
port: 8000
ssl_crt: /etc/pki/tls/certs/localhost.crt
ssl_key: /etc/pki/tls/private/salt_nopass.key
[root@salt-node4 /etc/salt/master.d]# vim eauth.conf
[root@salt-node4 /etc/salt/master.d]# cat eauth.conf
external_auth:
pam:
saltapi:
- .* # 代表能执行所有模块
- ‘@wheel‘ # 代表salt-key
- ‘@runner‘ # runner看机器是否存活。
重启saltmaster 和api
[root@salt-node4 /etc/salt/master.d]# systemctl restart salt-master
[root@salt-node4 /etc/salt/master.d]# systemctl restart salt-api
[root@salt-node4 master.d]# curl -k https://10.0.0.204:8000/login -H "Accept: application/x-yaml" -d username=‘saltapi‘ -d password=‘saltapi‘ -d eauth=‘pam‘
-----
return:
- eauth: pam
expire: 1490041767.050187
perms:
- .*
- ‘@wheel‘
- ‘@runner‘
start: 1489998567.050187
token: 3d625f75a04cb066e7d1f975d140ff5f96a56a47
user: saltapi
获得token后,我们使用获得的token查询minion的10.0.0.203的信息。它返回的是一个字典
curl -k https://10.0.0.204:8000/minions/test-node3.damaicha.org-203 -H "Accept: application/x-yaml" -H ‘X-Auth-Token: 3d625f75a04cb066e7d1f975d140ff5f96a56a47‘
通过runner查看那些机器活着
curl -k https://10.0.0.204:8000 -H "Accept: application/x-yaml" -H ‘X-Auth-Token: ef0b60cceb33fd66ab1ab3a8344671c461445d1c‘ -d client=‘runner‘ -d fun=‘manage.status‘
--------------
return:
- down: []
up:
- test-node3.damaicha.org-203
- salt-node4.damaicha.org-204
test.ping
[root@test-node3 sysconfig]# curl -k https://10.0.0.204:8000 -H "Accept: application/x-yaml" -H ‘X-Auth-Token: ef0b60cceb33fd66ab1ab3a8344671c461445d1c‘ -d client=‘local‘ -d tgt=‘*‘ -d fun=‘test.ping‘
----
return:
- salt-node4.damaicha.org-204: true
test-node3.damaicha.org-203: true
执行高级状态,有同步和异步,下面的是同步的比较慢。异步的是async
curl -k https://10.0.0.204:8000 -H "Accept: application/x-yaml" -H ‘X-Auth-Token: ef0b60cceb33fd66ab1ab3a8344671c461445d1c‘ -d client=‘local‘ -d tgt=‘*‘ -d fun=‘state.highstate‘
查看jobs
curl -k https://10.0.0.204:8000/jobs -H "Accept: application/x-yaml" -H ‘X-Auth-Token: ef0b60cceb33fd66ab1ab3a8344671c461445d1c‘
查看指定的jid 的执行内容
curl -k https://10.0.0.204:8000/jobs/20170320163206321875 -H "Accept: application/x-yaml" -H ‘X-Auth-Token: 3d625f75a04cb066e7d1f975d140ff5f96a56a47‘
