saltstack的深入-管理python-pip
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) [root@tvm-zabbix ~]# cd /etc/sysconfig/network-scripts/ [root@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 [root@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 [root@tvm-saltmaster base]# tree ops/ ops/ └── bin.sls 0 directories, 1 file [root@tvm-saltmaster base]# tree conf.d/ops/ conf.d/ops/ └── bin ├── pw ├── randchars.py └── sendEmail 1 directory, 3 files 2、sls配置 [root@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 [root@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin test=True [root@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin 增加到top.sls中 [root@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.
