Nginx部署

1.获取镜像

# 拉取镜像 此处我们拉取的是官方最新镜像，其它版本可以去DockerHub查询
[root@VM-24-9-centos ~]# docker pull nginx

2.创建容器

# 创建容器 第一个nginx是容器名，第二个nginx是镜像名
[root@VM-24-9-centos ~]# docker run -d -p 80:80 --name nginx nginx

3.把容器内的配置文件等复制到容器外用于挂载

# nginx的配置文件日志文件及默认的页面分别放于容器内的 /etc/nginx /usr/share/nginx/html /var/log/nginx 中,我们需要将其挂载到容器外部

# 创建三个文件夹 conf html logs
[root@VM-24-9-centos data]# mkdir -p /data/nginx/{conf.d,html,logs}

# 将容器内的 nginx.conf配置文件和default.conf配置文件复制出来
[root@VM-24-9-centos data]# docker cp nginx:/usr/share/nginx/html /data/nginx
[root@VM-24-9-centos data]# docker cp nginx:/etc/nginx/nginx.conf /data/nginx
[root@VM-24-9-centos data]# docker cp nginx:/etc/nginx/conf.d/default.conf /data/nginx/conf.d/default.conf

# 查看目录结构
[root@VM-24-9-centos nginx]# cd /data/nginx
[root@VM-24-9-centos nginx]# ll
total 16
drwxr-xr-x 2 root root 4096 Nov 16 10:48 conf.d
drwxr-xr-x 2 root root 4096 Nov 16 10:48 html
drwxr-xr-x 2 root root 4096 Nov 16 10:48 logs
-rw-r--r-- 1 root root  648 Nov  2 23:01 nginx.conf

4.删除之前的容器，然后创建新的容器把目录挂载上去

# 停止容器
[root@VM-24-9-centos nginx]# docker stop  nginx 
nginx
# 删除容器
[root@VM-24-9-centos nginx]# docker rm  nginx 
nginx
# 创建新的容器 --privileged=true 容器内部对挂载的目录拥有读写等特权
docker run -d -p 9200:9200 --name nginx_9200 \
-v /data/nginx/html:/usr/share/nginx/html \
-v /data/nginx/logs:/var/log/nginx \
-v /data/nginx/conf.d:/etc/nginx/conf.d \
-v /data/nginx/nginx.conf:/etc/nginx/nginx.conf \
--privileged=true \
nginx

5.访问nginx查看是否创建成功

[root@VM-24-9-centos ~]# curl http://x.x.x.x
