CentOS 7.2安装部署SaltStack

参考文档:

  1. Saltstack安装文档:https://repo.saltstack.com/#rhel

SaltStack的安装与简单配置,应用。

一.环境

Server:CentOS Linux release 7.2.1511 (Core)

Salt-master:172.18.12.201

Salt-minion:172.18.12.204

二.Saltstack安装与配置

1. yum安装

# Salt-master安装:
[[email protected] ~]# yum install https://repo.saltstack.com/yum/RedHat/salt-repo-latest-1.el7.noarch.rpm
[[email protected] ~]# yum clean expire-cache
[[email protected] ~]# yum install salt-master

# Salt-minion安装,最后一步安装组件有区别:
[[email protected] ~]# yum install salt-minion

2. 防火墙配置(salt-master)

# CentOS7.2默认自带firewall,无iptable;
# 移除系统自带firewall的开机启动,安装iptable,设置iptable开机启动
[[email protected] ~]# systemctl stop firewalld.service
[[email protected] ~]# systemctl disable firewalld.service
[[email protected] ~]# yum install iptables-services –y
[[email protected] ~]# systemctl enable iptables.service
[[email protected] ~]# systemctl restart iptables.service

# tcp4506是salt-master发送命令信息的端口,tcp4506是salt-minion返回信息的端口;
# Salt-minion可不做防火墙处理,默认iptable规则即可
[[email protected] ~]# vim /etc/sysconfig/iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 4505 -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 4506 -j ACCEPT

3. salt-master配置

#interface参数绑定master的通信ip,默认可不变更,表示所有主机ip;
[[email protected] ~]# sed -i 's/#interface: 0.0.0.0/interface: 172.18.12.201/g' /etc/salt/master

# hash_type参数默认可不变更,salt-master也可启动,但启动后有告警如下:
# [WARNING ] IMPORTANT: Do not use md5 hashing algorithm! Please set "hash_type" to sha256 in Salt Master config!
[[email protected] ~]# sed -i 's/#hash_type: md5/hash_type: sha256/g' /etc/salt/master

# auto_accept参数是自动认证开关,默认关闭,使用salt-key确认证书信任
[[email protected] ~]# sed -i 's/#auto_accept: False/auto_accept: True/g' /etc/salt/master

4. salt-minion配置

# master参数指定master 的ip (或者主机名),必配参数,如果minion启动时不能解析到master 主机,启动会失败;
[[email protected] ~]# sed -i 's/#master: salt/master: 172.18.12.201/g' /etc/salt/minion

# hash_type参数同master;
[[email protected] ~]# sed -i 's/#hash_type: sha256/hash_type: sha256/g' /etc/salt/master

# id参数设置salt-minion名,默认未设置,minio名取主机hostname中设定的主机名
[[email protected] ~]# sed -i 's/#id:/id: 172.18.12.204/g' /etc/salt/minion

5. 启动服务

启动salt-master

# 设置开机启动,启动后查看状态;
# 启动中有问题可通过"systemctl status salt-master.service"与"salt-mater -l debug"等命令定位故障,下面salt-minion相同
[[email protected] ~]# systemctl enable salt-master.service 
[[email protected] ~]# systemctl start salt-master.service
[[email protected] ~]# systemctl status salt-master.service

CentOS 7.2安装部署SaltStack

启动salt-minion

#设置开机启动,启动后查看状态
[[email protected] ~]# systemctl enable salt-minion.service
[[email protected] ~]# systemctl start salt-minion.service
[[email protected] ~]# systemctl status salt-mionion.service

CentOS 7.2安装部署SaltStack
 

6. 验证(salt-master)

查看minion表

[[email protected] ~]# salt-key -L

CentOS 7.2安装部署SaltStack

Salt-master已经设置"auto_accept"参数为"True",minion主机"172.18.12.204"已在"Acceptd Keys"中(主机名为salt-minion设置的id或hostname)。

手动认证key("auto_accept"参数为"False"时)

# -A指确认"Unacceptd Keys"中的全部minion(unacceptd中的minion列表为红色,确认到accepted列表中后变为绿色)
[[email protected] ~]# salt-key -A

# -a指"Unacceptd Keys"中特定的minion
# 或[[email protected] ~]# salt-key -a 172.18.12.204

简单的命令测试

# "*"表示所有"Acceptd Keys"中的minion,也可以对特定的minion执行命令;
# 返回值为"True"表示master与minion连接成功
[[email protected] ~]# salt "*" test.ping

CentOS 7.2安装部署SaltStack

#使用"cmd.run"可以执行具体的命令
[[email protected] ~]# salt "*" cmd.run "iptables -nL"
