使用znsible-playbook一键部署（rsync/nfs/nginx）
1.手写yaml
将如下json转为yaml
[
{
"0224": {
"老师": "于超",
"学生们": [
{
"黄彦": [
{
"年龄": 23,
"地址": "深圳"
}
],
"陈亮亮": [
{
"年龄": 24,
"地址": "广州"
}
],
"罗兴林": [
{
"年龄": 26,
"地址": "贵州"
}
]
}
]
}
}
]
- "0224":
老师: 于超
学生们:
- 黄彦:
- 年龄: 23
地址: 深圳
陈亮亮:
- 年龄: 24
地址: 广州
罗兴林:
- 年龄: 26
地址: 贵州
[
{
"0224": {
"老师": "于超",
"学生们": [
{
"黄彦": {
"年龄": 23,
"地址": "深圳"
}
},
{
"陈亮亮": {
"年龄": 24,
"地址": "广州"
}
},
{
"罗兴林": {
"年龄": 26,
"地址": "贵州"
}
}
]
}
}
]
2.练习jq命令处理json
json资料地址
使用jq命令
1.提取出 于超
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."老师" '
"于超"
2.提取出学生列表
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."学生们" '
[
{
"黄彦": {
"年龄": 23,
"地址": "深圳"
}
},
{
"陈亮亮": {
"年龄": 24,
"地址": "广州"
}
},
{
"罗兴林": {
"年龄": 26,
"地址": "贵州"
}
}
]
3.提取出罗兴林的资料
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."学生们" | .[2] '
{
"罗兴林": {
"年龄": 26,
"地址": "贵州"
}
}
4.提取出陈亮亮的资料
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."学生们" | .[1] '
{
"陈亮亮": {
"年龄": 24,
"地址": "广州"
}
}
5.提取出黄彦的地址
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."学生们" | .[0] | .[] | ."地址" '
"深圳"
6.提取出罗兴林的年龄
[root@master-61 ~]#cat 0224班.json | jq '.[]| .[] | ."学生们" | .[2] | .[] | ."年龄" '
26
