`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

**注意**:`密码有#等特殊字符会导致登陆失败，需要加上转义`  
`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`

      tasks:
        - name: 休眠10秒，防止刚开始登陆负载飙升

        - 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."
