rpm_快速安装saltstake
安装EPEL源:(mast和minion都需要安装) [root@c02 src]# wget http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm [root@c02 src]# rpm -ihv epel-release-6-8.noarch.rpm 安装rpmforge 在redhat6和centos 6的epel源上没有python-jinja2 salt-master:10.100.0.74 salt-minion:10.100.0.61 [root@salt-master ~]# yum install slat-master [root@salt-master ~]# chkconfig salt-master on [root@salt-master ~]# chkconfig --list|grep salt-master salt-master 0:off 1:off 2:on 3:on 4:on 5:on 6:off salt-minion端 [root@salt-minion ~]# yum install salt-minion -y [root@salt-minion ~]# chkconfig salt-minion on [root@salt-minion ~]# chkconfig --list |grep salt-minion salt-minion 0:off 1:off 2:on 3:on 4:on 5:on 6:off 查看salt-master的相关文件: [root@salt-master ~]# rpm -ql salt-master /etc/rc.d/init.d/salt-master /etc/salt/master /usr/bin/salt /usr/bin/salt-cp /usr/bin/salt-key /usr/bin/salt-master /usr/bin/salt-run /usr/bin/salt-unity /usr/share/man/man1/salt-cp.1.gz /usr/share/man/man1/salt-key.1.gz /usr/share/man/man1/salt-master.1.gz /usr/share/man/man1/salt-run.1.gz /usr/share/man/man1/salt-unity.1.gz /usr/share/man/man7/salt.7.gz 配份原始配置文件: [root@salt-master ~]# cp /etc/salt/master /etc/salt/master.bak 去掉下面几行的# [root@salt-master ~]# egrep -v "^#|^$" /etc/salt/master file_roots: base: - /srv/salt/ pillar_roots: #注意前面有个空格,不然会报错! base: - /srv/pillar [root@salt-master ~]# /etc/init.d/salt-master start Starting salt-master daemon: [ OK ] 查看salt-minion的相关文件: [root@salt-minion ~]# rpm -ql salt-minion /etc/rc.d/init.d/salt-minion /etc/salt/minion /usr/bin/salt-call /usr/bin/salt-minion /usr/share/man/man1/salt-call.1.gz /usr/share/man/man1/salt-minion.1.gz 配份原始文件: [root@salt-minion ~]# cp /etc/salt/minion /etc/salt/minion.bk 在/etc/salt/minion的16行去掉#改为master的IP或主机名 [root@salt-minion ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.100.0.74 salt-master [root@salt-minion ~]# egrep -v "^#|^$" /etc/salt/minion master: salt-master [root@salt-minion ~]# /etc/init.d/salt-minion start Starting salt-minion daemon: [ OK ] master端: 显示所有minion认证信息: [root@salt-master ~]# salt-key -L Accepted Keys: Denied Keys: Unaccepted Keys: salt-minion Rejected Keys: 接受salt-minion认证信息 [root@salt-master ~]# salt-key -a salt-minion The following keys are going to be accepted: Unaccepted Keys: salt-minion Proceed?
