Ansible
1、安装：
yum install -y ansible
2、使用：
cd /etc/ansible/
vim hosts
ansible all -m ping
ansible all -a "date"
-f 并行默认5, -m 模块默认命令, -a 命令
ansible all -m command -a "service httpd status"
3、ansible-doc -l
将本地文件批量上传到服务器
ansible-doc -s copy
ansible dbservers -m copy -a "src=/root/tmp_test_20180207.txt dest=/tmp/" #-f强制可替换已存在文件
报错： "msg": "Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!"
ansible dbservers -m command -a "rpm -q |grep libselinux-python"
ansible dbservers -m command -a "yum install -y libselinux-python"
再次执行成功
ansible dbservers -m command -a "getenforce" #是enforce,需要关闭selinux
ansible dbservers -m command -a "ls -l /tmp/tmp_test_20180207.txt"
4、ansible all -m cron -a 'name="custom job" minute=*/5 hour=* day=* month=* weekday=* job="/usr/sbin/ntpdate 210.72.145.44"'
5、开机自动启动：
ansible all -a "chkconfig --list iptables"
ansible all -a "service iptables status"
6、YAML
[root@db10 ~]# cat test.yaml
- hosts: all
remote_user: root
tasks:
- name: add a group
group: gid=1000 name=testgroup system=no
- name: excute a command
command: /bin/date
7、上传并执行脚本的两条语句
ansible all -m copy -a "src=/root/test.sh dest=/tmp/ owner=root group=root mode=0755"
ansible all -m shell -a "sh /tmp/test.sh" ######脚本中的命令一定要写全路径
-m 常用模块 command copy shell service cron file blockinfile
8、查看启动的端口：
ansible all -a "ss -tnl"
