saltstack自动运维工具--与mysql的结合,salt-ssh连接操作,salt-syndic模块,salt-api调用
将推送操作返回到数据库
在server5（master）中：
yum install mysql-server -y
[root@server5 files]# /etc/init.d/mysqld start
[root@server5 ~]# vim test.sql ###将17行注释掉
[root@server5 ~]# mysql < test.sql ##导入数据库

mysql> grant all on salt.* to salt@'172.25.3.%' identified by 'westos';在server4（minimo）端
vim /etc/salt/minion
修改其配置文件
814 mysql.host: '172.25.3.5'
815 mysql.user: 'salt'
816 mysql.pass: 'westos'
817 mysql.db: 'salt'
818 mysql.port: 3306
[root@server5 ~]# salt 'server4' test.ping --return mysql
server4:
True
[root@server5 ~]# mysql
mysql> use salt
mysql> select * from salt_returns;
第二种模式：
在server5（master）中：
[root@server5 ~]# yum install MySQL-python.x86_64 -y
[root@server5 salt]# vim master
[root@server5 salt]# /etc/init.d/salt-master restart修改master文件内容如下：
143 master_job_cache: mysql
144 mysql.host: 'localhost' ###定义主机名
145 mysql.user: 'salt' ###定义用户
146 mysql.pass: 'westos' ##定义密码
147 mysql.db: 'salt'
148 mysql.port: 3306
[root@server5 ~]# mysql
mysql> grant all on salt.* to salt@localhost identified by 'westos';
[root@server5 ~]# salt 'server4' test.ping --return mysql
server4: ##推送,将其返回到数据库
True
[root@server5 ~]# mysql
mysql> use salt
mysql> select * from salt_returns; ###查看返回信息
[root@server5 ~]# mkdir /srv/salt/_modules ##建立python函数模块
[root@server5 ~]# cd /srv/salt/_modules
[root@server5 _modules]# vim my_disk.py
#!/usr/bin/env python
def df():
return _salt_['cmd.run']('df -h')
[root@server5 _modules]# salt '*' saltutil.sync_modules
###同步模块数据
[root@server5 _modules]# salt '*' my_disk.df
##调用模块函数
salt-syndic模块
在server5上（原来的master）：
[root@server5 ~]# salt-key -d server7
###去掉server7这个节点
[root@server5 ~]# salt-key -L
###查看是否去除
在server7（top-master）上:
[root@server7 haproxy]# /etc/init.d/salt-minion stop
[root@server7 haproxy]# chkconfig salt-minion off
[root@server7 haproxy]# /etc/init.d/haproxy stop
[root@server7 haproxy]# /etc/init.d/keepalived stop
[root@server7 haproxy]# yum install -y salt-master
[root@server7 ~]# vim /etc/salt/master
[root@server7 ~]# /etc/init.d/salt-master start
在server5上（原来的master）：
[root@server5 ~]# yum install -y salt-syndic
[root@server5 ~]# /etc/init.d/salt-syndic start
[root@server5 ~]# vim /etc/salt/master
[root@server5 ~]# /etc/init.d/salt-master start编辑master配置文件：
在server7上：
[root@server7 ~]# salt-key -L ##查看节点
Accepted Keys:
Denied Keys:
Unaccepted Keys:
server5
Rejected Keys:
[root@server7 ~]# salt-key -A ##添加节点
[root@server7 ~]# salt '*' test.ping
执行,会发现看到其它节点,topmaster实际上看的时server5的master
salt-ssh连接操作
[root@server5 ~]# yum install salt-ssh -y
[root@server5 ~]# vim /etc/salt/roster
[root@server5 ~]# vim /etc/salt/master
###将之前写的数据库的模块注释掉
关闭server6的minion,通过ssh连接,成功
salt-api调用
[root@server5 ~]# yum install salt-api -y
[root@server5 ~]# cd /etc/pki/
[root@server5 pki]# ls
CA ca-trust entitlement java nssdb product rpm-gpg rsyslog tls
[root@server5 pki]# cd tls/private/
[root@server5 private]# ls
[root@server5 private]# openssl genrsa 1024
[root@server5 private]# openssl genrsa 1024 > localhost.key
Generating RSA private key, 1024 bit long modulus
.......++++++
...............................................++++++
e is 65537 (0x10001)
[root@server5 tls]# cd certs/
[root@server5 certs]# make testcert
[root@server5 certs]# cd /etc/salt/
[root@server5 salt]# cd master.d/
[root@server5 master.d]# pwd
/etc/salt/master.d
[root@server5 master.d]# vim api.conf ###写api调用文件
rest_cherrypy:
port: 8000
ssl_crt: /etc/pki/tls/certs/localhost.crt
ssl_key: /etc/pki/tls/private/localhost.key
[root@server5 master.d]# vim auth.conf ###写认证文件
external_auth:
pam:
saltapi:
- '.*'
- '@wheel'
- '@runner'
- '@jobs'
[root@server5 master.d]# useradd saltapi ##建立用户
[root@server5 master.d]# passwd saltapi ###设置用户密码
[root@server5 master.d]# /etc/init.d/salt-master stop
