ansible-的修改配置文件

1. ansible的配置文件

[root@1-230 python-2.7.5]# tree /etc/ansible/
/etc/ansible/
├── ansible.cfg
├── hosts
└── roles

1 directory, 2 files

　　ansible.cfg：是ansible执行需求的全局性、默认的配置文件
　　hosts：默认的主机资产清单文件

3.Ansible.cfg是ansible自动化任务所用的一个核心配置文件，大部分的配置文件都集中在defualts配置项目中。以下需要修改的配置

    1）inventory 
    该参数表示资源清单inventory文件的位置，资源清单就是一些Ansible需要连接管理的主机列表 
    inventory = /root/ansible/hosts
    
    2）library 
    Ansible的操作动作，无论是本地或远程，都使用一小段代码来执行，这小段代码称为模块，这个library参数就是指向存放Ansible模块的目录 
    library = /usr/share/ansible
    
    3）forks 
    设置默认情况下Ansible最多能有多少个进程同时工作，默认设置最多5个进程并行处理。具体需要设置多少个，可以根据控制主机的性能和被管理节点的数量来确定。 
    forks = 5
    
    4）sudo_user 
    这是设置默认执行命令的用户，也可以在playbook中重新设置这个参数 
    sudo_user = root
    //注意:新版本已经作了修改，如ansible2.4.1下已经为：
    default_sudo_user = root 
    
    5）remote_port 
    这是指定连接被关节点的管理端口，默认是22，除非设置了特殊的SSH端口，不然这个参数一般是不需要修改的 
    remote_port = 22
    
    6）host_key_checking 
    这是设置是否检查SSH主机的密钥。可以设置为True或False 
    host_key_checking = False
    
    7）timeout 
    这是设置SSH连接的超时间隔，单位是秒。 
    timeout = 20
    
    8）log_path 
    Ansible系统默认是不记录日志的，如果想把Ansible系统的输出记录到人i治稳健中，需要设置log_path来指定一个存储Ansible日志的文件 
    log_path = /var/log/ansible.log
    
    另外需要注意，执行Ansible的用户需要有写入日志的权限，模块将会调用被管节点的syslog来记录，口令是不会出现的日志中的
    
    9）private_key_file
    
    默认
    private_key_file=/path/to/file.pem
    
    在使用ssh公钥私钥登录系统时候，需要修改密钥路径。
    private_key_file = /root/.ssh/id_rsa
    
    10）deprecation_warnings
            #deprecation_warnings = True
            注释：
            以上使用的默认的，配置会提示警告信息，我们需要修改为False，关闭警告
            [DEPRECATION WARNING]: DEFAULT_SUDO_USER option, In favor of Ansible Become, which is a generic framework. See become_user. , use become instead. This feature will be 
            removed in version 2.8. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
            
            deprecation_warnings = False
