ansible hosts 格式

name1 ansible_ssh_host=*.*.*.* ansible_ssh_user=root ansible_ssh_pass=* ansible_ssh_port=22
name2 ansible_ssh_host=*.*.*.* ansible_ssh_user=root ansible_ssh_pass=* ansible_ssh_port=22

name1 ：别名，可以写服务器名称
ansible_ssh_user：登陆账号，默认值在ansible.cfg中定义
ansible_ssh_pass：登陆密码
ansible_ssh_port：登录端口

加、解密 hosts

[root@yx01 ansible_playbook]# ansible-vault encrypt /etc/ansible/hosts 
New Vault password: 
Confirm New Vault password: 
Encryption successful

playbook code

---
- hosts: all
  remote_user: root
  gather_facts: True
  tasks:
    - name: 休眠10秒，防止刚开始登陆负载飙升
      shell: "sleep 10"
    - name: 过滤负载信息
      shell: "top -c -n 1 -b|grep load|grep -v grep|awk '{print $(NF-2),$(NF-1),$NF}'"
    - name: 过滤cpu信息
      shell: "top -c -n 1 -b|grep Cpu|grep -v grep|cut -c 10-"

shell code

#!/bin/bash

localtime=`date "+%Y-%m-%d_%H:%M:%S"`
logfile=logs/${
    
    localtime}.txt

if [ "$(ls -A logs)" ]
then
echo "-------start time:$localtime-------"
    rm -rf logs/*
fi

# 获取信息，--verbose将执行回显输出
# 添加 --ask-vault-pass参数手动交互式的输入密码
# 添加 --vault-password-file 指定存放密码的文件
ansible-playbook collect.yml --verbose > logs/tempfile.txt
# 过滤负载信息
cat logs/tempfile.txt |grep load|awk '{print $(NF-2),$(NF-1),$NF}'|sed 's/\[\"//g'|sed 's/\"\]\}//g' > $logfile
# 过滤cpu信息
cat logs/tempfile.txt|grep Cpu|egrep -o "\[\".*\"\]\}"|sed 's/\[\"//g'|sed 's/\"\]\}//g' >> $logfile

localtime=`date "+%Y-%m-%d_%H:%M:%S"`
echo "-------end time:$localtime-------"

解决ansible首次连接host服务器需验证问题

 "msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host."

修改/etc/ansible/ansible.cfg，放开注释
