`因为服务器比较多，一个个添加比较麻烦，故写个shell脚本批量添加`

#### 测试代码 ####

#!/bin/bash
    set -x
    
    wan=(wan1 wan2 ...)
    lan=(lan1 lan2 ...)
    domains=yx
    n=0 
    for i in ${ wan[@]}
    do
    	# 跳过已添加的
        isEnvSet=$(ansible $i -m shell -a 'cat ~/.bashrc | grep domain')
        if [[ $isEnvSet ]]
        then
            continue
        fi  
        ansible $i -m shell -a 'echo \# sid >> ~/.bashrc'
        ansible $i -m shell -a 'echo "export domain='${ domains[n]}'" >> ~/.bashrc'
        ansible $i -m shell -a 'echo "export rsspWan='${ wan[n]}'" >> ~/.bashrc'
        ansible $i -m shell -a 'echo "export rsspLan='${ lan[n]}'" >> ~/.bashrc'
    
        if [[ $n -ge 15 ]]
        then
            ansible $i -m shell -a 'echo export isMaster=yes >> ~/.bashrc'
        fi  
        ansible $i -m shell -a 'source ~/.bashrc'
        
        # 输出
        ansible $i -m shell -a 'tail -4 ~/.bashrc'
        # 测试
        ansible $i -m shell -a 'echo $domain'
        ansible $i -m shell -a 'echo $rsspWan'
        ansible $i -m shell -a 'echo $rsspLan'
        ansible $i -m shell -a 'echo $isMaster'
        let n++ 
    done

`这里需要注意的是使用ansible命令时，后面接的单引号和双引号取值的问题`

`查看输出信息`
