操作内容： 一、基础环境 1、使用tvm-saltmaster操作 2、网络： eth0：host-only（用于虚拟内网，手动固定IP，这样从宿主机可以直接连接到这个vm） eth1：NAT（用于上外网，动态IP） [iyunv@tvm-zabbix ~]# cd /etc/sysconfig/network-scripts/ [iyunv@tvm-zabbix network-scripts]# cat ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=192.168.56.253 PREFIX=24 GATEWAY=192.168.56.1 DNS1=192.168.56.254 [iyunv@tvm-zabbix network-scripts]# cat ifcfg-eth1 DEVICE=eth1 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp DNS1=192.168.56.254 二、配置 1、文件结构 [iyunv@tvm-saltmaster base]# tree ops/ ops/ └── bin.sls 0 directories, 1 file [iyunv@tvm-saltmaster base]# tree conf.d/ops/ conf.d/ops/ └── bin     ├── pw     ├── randchars.py     └── sendEmail 1 directory, 3 files 2、sls配置 [iyunv@tvm-saltmaster base]# cat ops/bin.sls ## 此处列出需要的软件包 # python-pip:   pkg.installed:     - name: python-pip     - require_in:       -file: pip-pkgs pip-pkgs:   pip.installed:     - names:       - virtualenvwrapper       - pwgen /usr/bin/sendEmail:   file.managed:     - source: salt://conf.d/ops/bin/sendEmail     - mode: 755 /usr/bin/pw:   file.managed:     - source: salt://conf.d/ops/bin/pw     - mode: 755 /usr/bin/randchars:   file.managed:     - source: salt://conf.d/ops/bin/randchars.py     - mode: 755             三、执行 [iyunv@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin test=True [iyunv@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin 增加到top.sls中 [iyunv@tvm-saltmaster base]# cat top.sls base:   'tvm-yum':     - dnsmasq     - crontab     - web   'tvm-zabbix':     - mysql.server     - zabbix.server     - zabbix.web   '*':     - abc     - monit     - postfix     - salt.minion     - ssh     - vim     - zabbix.agent     - ops.bin       四、总结 此处使用到： pip.installed 使用时，需确保安装了python-pip这个包，否则会提示异常。 且pip安装包时，对应的主机可以连接到外网，如果没联网，有如下报错： ----------           ID: pip-pkgs     Function: pip.installed         Name: virtualenvwrapper       Result: False      Comment: Failed to install packages: virtualenvwrapper.
