Saltstack安装文档:
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: [root@localhost ~]# yum install https://repo.saltstack.com/yum/RedHat/salt-repo-latest-1.el7.noarch.rpm [root@localhost ~]# yum clean expire-cache [root@localhost ~]# yum install salt-master # Salt-minion安装,最后一步安装组件有区别: [root@localhost ~]# 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
[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# systemctl disable firewalld.service
[root@localhost ~]# yum install iptables-services –y
[root@localhost ~]# systemctl enable iptables.service
[root@localhost ~]# 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
[root@localhost ~]# 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
#interface参数绑定master的通信ip,默认可不变更,表示所有主机ip; [root@localhost ~]# 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! [root@localhost ~]# 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 [root@localhost ~]# 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; [root@localhost ~]# sed -i 's/#master: salt/master: 172.18.12.201/g' /etc/salt/minion # hash_type参数同master; [root@localhost ~]# 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 [root@localhost ~]# 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 [root@localhost ~]# systemctl enable salt-master.service [root@localhost ~]# systemctl start salt-master.service [root@localhost ~]# systemctl status salt-master.service
启动salt-minion
#设置开机启动,启动后查看状态 [root@localhost ~]# systemctl enable salt-minion.service [root@localhost ~]# systemctl start salt-minion.service [root@localhost ~]# systemctl status salt-mionion.service
6. 验证(salt-master) 查看minion表
[root@localhost ~]# salt-key -L
