Docker-compose详解和LNMP搭建全过程

#获取在线源
curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
#安装，给予执行权限
chmod +x /usr/local/bin/docker-compose
#查看版本
docker-compose --version

#下载好安装包，直接上传到系统，给执行权限，放在指定目录
chmod +x docker-compose
mv docker-compose /usr/local/bin/

animals: pets #对象映射: 键值对的字典

pets: #对象映射:

- cat - 序列值

- dog

- pig



pets: ["cat", "dog", "pig"] #另一种表达格式

#序列的映射，是指针对一个对象，序列中的值都属于该对象，如蔬菜包含包菜、胡萝卜、土豆等。
vegetables:
- potato
- carrot
- cabbage
#映射的映射，是指针对一个对象有多个子对象，分别有他们的值，如系统状态包含cpu、内存、网络、磁盘等。
vmstat:
cpu: 2
memory: 4G
disk: 100G
network:
ipv4: 192.168.1.1
netmask: 255.255.255.0
gateway: 192.168.1.254
dns: 8.8.8.8

debug: true #真true，假false，不能用引号引用
debug: false

value: | # | 代表保留输出文本的换行和回车符，不加的话即使文本换行也会在同一行显示
hello #这种情况就是输出 hello ，不加 | 就是 helloworld!
world! world!

| - #不保留文本块末尾的换行 | + #会保留文本块末尾的换行
value: > hello #将 > 后的字符串和之后的字符串用空格分开，即 hello world!
world!

type: &a string #&是打锚点，后面跟的是锚点名称，&a 代表的就是 string
type: *a #*a 代表引用锚点，此处输出结果就是 type: string
types: #此处就是输出 types:
- int - int
- *a - string
- double - double

pets:
- cat
- dog
- pig

--- #可以将多个yml文件写入一个yml文件中，使用 --- 作为分隔符
