一、使用容器运行Nginx应用
1.1 使用docker run命令运行Nginx应用
1.1.1 观察下载容器镜像过程
查找本地容器镜像文件
执行命令过程一：下载容器镜像
# docker run -d nginx:latest
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx
a2abf6c4d29d: Downloading 1.966MB/31.36MB 下载中
a9edb18cadd1: Downloading 1.572MB/25.35MB
589b7251471a: Download complete 下载完成
186b1aaa4aa6: Download complete
b4df32aa5a72: Waiting 等待下载
a0bcbecc962e: Waiting
执行命令过程二：下载容器镜像
[root@localhost ~]# docker run -d nginx:latest
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx
a2abf6c4d29d: Downloading 22.87MB/31.36MB
a9edb18cadd1: Downloading 22.78MB/25.35MB
589b7251471a: Waiting
186b1aaa4aa6: Waiting
b4df32aa5a72: Waiting
执行命令过程三：下载容器镜像
[root@localhost ~]# docker run -d nginx:latest
Unable to find image 'nginx:latest' locally
latest: Pulling from library/nginx
a2abf6c4d29d: Pull complete 下载完成
a9edb18cadd1: Pull complete
589b7251471a: Pull complete
186b1aaa4aa6: Pull complete
b4df32aa5a72: Waiting 等待下载
1.1.2 观察容器运行情况
# docker run -d nginx:latest
9834c8c18a7c7c89ab0ea4119d11bafe9c18313c8006bc02ce57ff54d9a1cc0c
命令解释
docker run 启动一个容器
-d 把容器镜像中需要执行的命令以daemon（守护进程）的方式运行
nginx 应用容器镜像的名称，通常表示该镜像为某一个软件
latest 表示上述容器镜像的版本，表示最新版本，用户可自定义其标识，例如v1或v2等
# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9834c8c18a7c nginx:latest "/docker-entrypoint.…" 24 seconds ago Up 23 seconds 80/tcp condescending_pare
命令解释
docker ps 类似于Linux系统的ps命令，查看正在运行的容器，如果想查看没有运行的容器，需要在此命令后使用--all
输出内容解释
| CONTAINERID | IMAGE | COMMAND | CREATED | STATUS | PORTS | NAMES |
|---|---|---|---|---|---|---|
| 9834c8c18a7c | nginx:latest | “/docker-entrypoint.…” | 24 seconds ago | Up 23 seconds | 80/tcp | condescending_pare |
1.2 访问容器中运行的Nginx服务
1.2.1 确认容器IP地址
实际工作中不需要此步操作。
# docker inspect 9834
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"IPAddress": "172.17.0.2", 容器IP地址
"IPPrefixLen": 16,
"IPv6Gateway": "",
"MacAddress": "02:42:ac:11:00:02",
"Networks": {
"bridge": {
"IPAMConfig": null,
"Links": null,
"Aliases": null,
"NetworkID": "d3de2fdbc30ee36a55c1431ef3ae4578392e552009f00b2019b4720735fe5a60",
"EndpointID": "d91f47c9f756ff22dc599a207164f2e9366bd0c530882ce0f08ae2278fb3d50c",
"Gateway": "172.17.0.1",
"IPAddress": "172.17.0.2", 容器IP地址
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"MacAddress": "02:42:ac:11:00:02",
"DriverOpts": null
}
}
}
}
]
命令解释
docker inspect 为查看容器结构信息命令
9834 为前面生成的容器ID号前4位，使用这个ID号时，由于其较长，使用时能最短识别即可。
1.2.2 容器网络说明
# ip a s
......
docker0网桥，用于为容器提供桥接，转发到主机之外的网络
5: docker0: ,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
link/ether 02:42:d5:c3:d4:cc brd ff:ff:ff:ff:ff:ff
inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
valid_lft forever preferred_lft forever
inet6 fe80::42:d5ff:fec3:d4cc/64 scope link
valid_lft forever preferred_lft forever
与容器中的虚拟网络设备在同一个命名空间中，用于把容器中的网络连接到主机
9: veth393dece@if8: ,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master docker0 state UP group default
link/ether 02:e3:11:58:54:0f brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet6 fe80::e3:11ff:fe58:540f/64 scope link
valid_lft forever preferred_lft forever
1.2.3 使用curl命令访问
# curl http://172.17.0.2
返回结果，表示访问成功！

在上一节我们提到了显示使用Ehcache锁的问题，其实我们还可以隐式的来使用Ehcache的锁，那就是通过BlockingCache。BlockingCache是Ehcache的一个封装类，可以让我们对Ehcache进行并发操作。其内部的锁机制是使用的net.</div>

npm is the package manager for node
官方网站：https://www.npmjs.com/
npm上有很多优秀的nodejs包，来解决常见的一些问题，比如用node-mysql，就可以方便通过nodejs链接到mysql，进行数据库的操作
在开发过程往往会需要用到其他的包，使用npm就可以下载这些包来供程序调用
