[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) [root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]#
(1)修改selinux配置文件：
[root@localhost ~]# vim /etc/sysconfig/selinux SELINUX=enforcing 改为 SELINUX=disabled
(2)关闭防火墙：
[root@localhost ~]# systemctl disable firewalld [root@localhost ~]# systemctl stop firewalld [root@localhost ~]# iptables -F [root@localhost ~]# iptables -L
IP分配如下：
master 192.168.112.140
minion 192.168.112.141
minion 192.168.112.142
(3)master和minion端部署安装
master端执行:
[root@localhost ~]# yum install epel-release [root@localhost ~]# yum install -y salt-master
minion端执行:
[root@localhost ~]# yum install epel-release [root@localhost ~]# yum install salt-minion
(4)修改配置文件:
[root@localhost ~]# vim /etc/salt/minion master: 192.168.112.140 id: server02 [root@localhost ~]# [root@localhost ~]# systemctl start salt-minion [root@localhost ~]# ps -ef|grep salt-minion root 2505 1 2 23:06 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion root 2508 2505 8 23:06 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion root 2536 2318 0 23:06 pts/0 00:00:00 grep --color=auto salt-minion [root@localhost ~]# netstat -lnupt|grep 4505 tcp 0 0 0.0.0.0:4505 0.0.0.0:* LISTEN 2304/python [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# vim /etc/salt/minion master: 192.168.112.140 id: server03 [root@localhost ~]# [root@localhost ~]# systemctl start salt-minion [root@localhost ~]# ps -ef|grep salt-minion root 2487 1 1 23:05 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion root 2490 2487 4 23:06 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion root 2521 2320 0 23:06 pts/0 00:00:00 grep --color=auto salt-minion [root@localhost ~]# [root@localhost ~]# [root@localhost ~]#
(5)设置salt-master和salt-minion开机启动
[root@localhost ~]# systemctl enable salt-master Created symlink from /etc/systemd/system/multi-user.target.wants/salt-master.service to /usr/lib/systemd/system/salt-master.service. [root@localhost ~]# [root@localhost ~]# systemctl enable salt-minion Created symlink from /etc/systemd/system/multi-user.target.wants/salt-minion.service to /usr/lib/systemd/system/salt-minion.service. [root@localhost ~]#
2、配置saltstack认证
salt-key //查看已经签名的客户端
salt-key -a //签名指定的主机
salt-key -A //签名所有的主机
salt-key -d //删除指定主机的签名
salt-key --help //查看各命令的用法
[root@localhost ~]# salt-key Accepted Keys: Denied Keys: Unaccepted Keys: server02 server03 Rejected Keys: [root@localhost ~]# [root@localhost ~]# salt-key -a server02 The following keys are going to be accepted: Unaccepted Keys: server02 Proceed? [n/Y] Y Key for minion server02 accepted. [root@localhost ~]# [root@localhost ~]# salt-key Accepted Keys: server02 server03 Denied Keys: Unaccepted Keys: Rejected Keys: [root@localhost ~]#
3、日常用法
test.ping用户检查master到minion端的网络连通性，返回True即正常，False为异常
[root@localhost ~]# salt '*' test.ping server02: True server03: True [root@localhost ~]#
cmd.run 在minion端执行shell命令，记住这模块只能执行短连接命令，比如df命令；长连接的无法返回结果，比如top命令
[root@localhost ~]# salt '*' cmd.run 'hostname' server03: localhost.localdomain server02: localhost.localdomain [root@localhost ~]# salt '*' cmd.run 'df -Th' server02: Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 xfs 90G 1.8G 89G 2% / devtmpfs devtmpfs 231M 0 231M 0% /dev tmpfs tmpfs 241M 12K 241M 1% /dev/shm tmpfs tmpfs 241M 4.6M 236M 2% /run tmpfs tmpfs 241M 0 241M 0% /sys/fs/cgroup /dev/sda1 xfs 1014M 131M 884M 13% /boot tmpfs tmpfs 49M 0 49M 0% /run/user/0 server03: Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 xfs 90G 1.8G 89G 2% / devtmpfs devtmpfs 231M 0 231M 0% /dev tmpfs tmpfs 241M 12K 241M 1% /dev/shm tmpfs tmpfs 241M 4.6M 236M 2% /run tmpfs tmpfs 241M 0 241M 0% /sys/fs/cgroup /dev/sda1 xfs 1014M 131M 884M 13% /boot tmpfs tmpfs 49M 0 49M 0% /run/user/0 [root@localhost ~]#

如果要获取具体某一项内容，可以直接在该命令后加项名，比如获取操作系统，则：
[root@localhost ~]# salt -L 'server02,server03' grains.item os server03: ---------- os: CentOS server02: ---------- os: CentOS [root@localhost ~]#
同样可以获取host、ip_interfaces、fqdn_ipv4、cpu_model对应的值：
[root@localhost ~]# salt 'server02' grains.item host server02: ---------- host: server02 [root@localhost ~]# [root@localhost ~]# salt 'server02' grains.item ip_interfaces server02: ---------- ip_interfaces: ---------- eth0: - 192.168.112.141 lo: - 127.0.0.1 [root@localhost ~]# [root@localhost ~]# salt 'server02' grains.item fqdn_ip4 server02: ---------- fqdn_ip4: - 192.168.112.141 [root@localhost ~]# [root@localhost ~]# salt 'server02' grains.item cpu_model server02: ---------- cpu_model: Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz [root@localhost ~]#
4、常用模块介绍
(1)、cp模块（实现远程文件、目录的复制，以及下载URL文件等操作）
#将主服务器file_roots指定位置下的目录复制到被控主机
打开master文件中的
#file_roots:
base:
- /srv/salt
改为：
file_roots:
base:
- /srv/salt
# salt '*' cp.get_dir salt://test_dir /data
salt:// --->表示file_root指定的路径，这里是/srv/salt，salt://test_dir 表示/srv/salt/test_dir
/data --->表示目标主机上的根目录下的data目录
[root@localhost ~]# ll /srv/salt/test_dir/ total 672 -rw-r--r-- 1 root root 686011 May 7 22:37 nginx-1.0.10.tar.gz [root@localhost ~]# salt '*' cp.get_dir salt://test_dir /data server02: - /data/test_dir/nginx-1.0.10.tar.gz server03: - /data/test_dir/nginx-1.0.10.tar.gz [root@localhost ~]# salt '*' cmd.run 'ls -l /data' server03: total 0 drwxr-xr-x 2 root root 33 Jun 1 02:12 test_dir server02: total 0 drwxr-xr-x 2 root root 33 Jun 1 02:12 test_dir [root@localhost ~]#
#将主服务器file_roots指定位置下的文件复制到被控主机
# salt '*' cp.get_file salt://nginx-1.0.10.tar.gz /root/nginx-1.0.10.tar.gz
[root@localhost salt]# salt '*' cp.get_file salt://nginx-1.0.10.tar.gz /root/nginx-1.0.10.tar.gz server02: /root/nginx-1.0.10.tar.gz server03: /root/nginx-1.0.10.tar.gz [root@localhost salt]# salt '*' cmd.run 'ls -l /root/' server02: total 676 -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz server03: total 676 -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz [root@localhost salt]#
对于大文件，cp_get_file支持gzip压缩，在参数中指定gzip的压缩级别，如下:
[root@server01 salt]# pwd /srv/salt [root@server01 salt]# ll -th test -rw-r--r-- 1 root root 1.0G Jun 13 22:04 test [root@server01 salt]# salt '*' cp.get_file salt://test /root/test gzip=5 server02: /root/test server03: /root/test [root@server01 salt]# [root@server01 salt]# salt '*' cmd.run 'ls -htl /root/test' server02: -rw-r--r-- 1 root root 1.0G Jun 13 22:06 /root/test server03: -rw-r--r-- 1 root root 1.0G Jun 13 22:06 /root/test [root@server01 salt]#
其中，1代表最小压缩，9代表最大压缩，gzip参数是在传输过程中对文件进行压缩。
cp.get_file默认不会在客户端上建立目录，如果客户端上没有这个目录了，文件拷贝将失败，所以这里又有一个参数makedirs，当客户端上的目标目录不存在时，直接将该参数的值设置为True，即makedirs=True；
[root@server01 salt]# salt '*' cmd.run 'ls -l /root/' server02: total 1049372 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 260 Jun 5 22:08 connect.py -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz -rw-r--r-- 1 root root 1073741824 Jun 13 22:06 test drwxr-xr-x 2 root root 33 Jun 13 22:54 web server03: total 1049368 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz -rw-r--r-- 1 root root 1073741824 Jun 13 22:06 test drwxr-xr-x 2 root root 33 Jun 13 22:54 web [root@server01 salt]# [root@server01 salt]# salt '*' cp.get_file salt://nginx-1.0.10.tar.gz /root/web/nginx-1.0.10.tar.gz makedirs=True server02: /root/web/nginx-1.0.10.tar.gz server03: /root/web/nginx-1.0.10.tar.gz [root@server01 salt]# [root@server01 salt]# salt '*' cmd.run 'ls -l /root/' server02: total 1049372 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 260 Jun 5 22:08 connect.py -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz -rw-r--r-- 1 root root 1073741824 Jun 13 22:06 test drwxr-xr-x 2 root root 33 Jun 13 22:54 web server03: total 1049368 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz -rw-r--r-- 1 root root 1073741824 Jun 13 22:06 test drwxr-xr-x 2 root root 33 Jun 13 22:54 web [root@server01 salt]#
注意：cp.get_file从字面上就可以看出是操作对象是文件，即只有在拷贝文件的时候，目标主机上对应的目录不存在使用makedirs参数才有用，否则该参数无效。
#下载指定URL内容到被控主机指定位置
salt '*' cp.get_url http://dl.fedoraproject.org/pub/epel/6/x86_64/GeoIP-1.6.5-1.el6.x86_64.rpm /root/GeoIP-1.6.5.-1.e16.x86_64.rpm
cp.get_url 根据指定的url地址下载文件到被控端主机的对应目录下，这里被控端目录/root/下面
[root@localhost salt]# salt '*' cmd.run 'ls -l /root/' server02: total 676 -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz server03: total 676 -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz [root@localhost salt]# salt '*' cp.get_url http://dl.fedoraproject.org/pub/epel/6/x86_64/GeoIP-1.6.5-1.el6.x86_64.rpm /root/GeoIP-1.6.5.-1.e16.x86_64.rpm server03: /root/GeoIP-1.6.5.-1.e16.x86_64.rpm server02: /root/GeoIP-1.6.5.-1.e16.x86_64.rpm [root@localhost salt]# salt '*' cmd.run 'ls -l /root/' server02: total 792 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz server03: total 792 -rw-r--r-- 1 root root 115316 Jun 1 02:26 GeoIP-1.6.5.-1.e16.x86_64.rpm -rw-------. 1 root root 1496 Jan 17 09:03 anaconda-ks.cfg -rw-r--r-- 1 root root 686011 Jun 1 02:15 nginx-1.0.10.tar.gz [root@localhost salt]#
当然URL也可以是master上的路径（salt://）
[root@server01 salt]# salt '*' cp.get_url salt://nginx-1.0.10.tar.gz /opt/nginx-1.0.10.tar.gz server02: /opt/nginx-1.0.10.tar.gz server03: /opt/nginx-1.0.10.tar.gz [root@server01 salt]# salt '*' cmd.run 'ls -l /opt' server02: total 672 -rw-r--r-- 1 root root 686011 Jun 13 23:05 nginx-1.0.10.tar.gz server03: total 672 -rw-r--r-- 1 root root 686011 Jun 13 23:05 nginx-1.0.10.tar.gz [root@server01 salt]#
#salt '*' cp.hash_file salt://test-file
cp.hash_file获取从主控端下发到被控端后文件的hash值，一般用于对比某个被控端某个文件的hash值
[root@localhost ~]# salt '*' cp.hash_file salt://nginx-1.0.10.tar.gz server02: ---------- hash_type: md5 hsum: 930b297b00fa1018fb0a1dd3e6b7e17e server03: ---------- hash_type: md5 hsum: 930b297b00fa1018fb0a1dd3e6b7e17e [root@localhost ~]#
(2)、cmd模块（实现远程的命令行调用执行）
# salt '*' cmd.run 'netstat -ntlp'
[root@localhost salt]# salt '*' cmd.run 'netstat -lnupt' server02: Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1184/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2013/master tcp6 0 0 :::22 :::* LISTEN 1184/sshd tcp6 0 0 ::1:25 :::* LISTEN 2013/master udp 0 0 0.0.0.0:32525 0.0.0.0:* 737/dhclient udp 0 0 127.0.0.1:323 0.0.0.0:* 672/chronyd udp 0 0 0.0.0.0:68 0.0.0.0:* 737/dhclient udp6 0 0 ::1:323 :::* 672/chronyd udp6 0 0 :::14472 :::* 737/dhclient server03: Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1191/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1835/master tcp6 0 0 :::22 :::* LISTEN 1191/sshd tcp6 0 0 ::1:25 :::* LISTEN 1835/master udp 0 0 0.0.0.0:32525 0.0.0.0:* 729/dhclient udp 0 0 127.0.0.1:323 0.0.0.0:* 661/chronyd udp 0 0 0.0.0.0:68 0.0.0.0:* 729/dhclient udp6 0 0 ::1:323 :::* 661/chronyd udp6 0 0 :::14472 :::* 729/dhclient [root@localhost salt]#
(3)、cron模块（实现被控主机的crontab操作）
## 为指定的被控主机、root用户添加crontab信息
# salt '*' cron.set_job root '*/5' '*' '*' '*' '*' 'date >/dev/null 2>&1'
# salt '*' cron.raw_cron root
[root@localhost salt]# salt '*' cron.set_job root '*/60' '*' '*' '*' '*' '/usr/local/nginx/sbin/nginx -s reload >/dev/null 2>&1' server02: new server03: new [root@localhost salt]# [root@localhost salt]# salt '*' cmd.run 'crontab -l' server03: # Lines below here are managed by Salt, do not edit */60 * * * * /usr/local/nginx/sbin/nginx -s reload >/dev/null 2>&1 server02: # Lines below here are managed by Salt, do not edit */60 * * * * /usr/local/nginx/sbin/nginx -s reload >/dev/null 2>&1 [root@localhost salt]#
## 删除指定的被控主机、root用户的crontab信息
[root@localhost salt]# salt '*' cron.rm_job root '/usr/local/nginx/sbin/nginx -s reload >/dev/null 2>&1' server02: removed server03: removed [root@localhost salt]# salt '*' cmd.run 'crontab -l' server03: # Lines below here are managed by Salt, do not edit server02: # Lines below here are managed by Salt, do not edit [root@localhost salt]#
(4)、DNSutil模块（实现被控主机通用DNS操作）
给被控制端添加指定的hosts配置项目，即host主机记录
#salt '*' dnsutil.hosts_append /etc/hosts 192.168.112.140 server01
