docker安装nginx

docker部署nginx非常简单难的是如何定义nginx.conf与部署html下的前端文件

# 拉取镜像

[root@localhost ~]# docker pull nginx:1.14.0
[root@localhost ~]# docker images
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
nginx                1.14.0              ecc98fc2f376        2 years ago         109MB

# 启动

[root@localhost ~]# docker run --name nginx-test -p 8080:80 -d nginx:1.14.0
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES

这时候访问本机ip：8080 就能看到熟悉的Welcome to nginx！

# 自定义nginx

进入容器

[root@localhost ~]# docker exec -it 8657715d04a5 /bin/bash
root@8657715d04a5:/# ls
bin  boot  dev	etc  home  lib	lib64  media  mnt  opt	proc  root  run  sbin  srv  sys  tmp  usr  var
root@8657715d04a5:/#

查找对应路径

root@8657715d04a5:/# find / -name nginx
/etc/default/nginx
/etc/init.d/nginx
/etc/logrotate.d/nginx
/etc/nginx # 配置文件路径
/usr/lib/nginx
/usr/sbin/nginx # 启停
/usr/share/doc/nginx 
/usr/share/nginx # 默认html存放路径
/var/cache/nginx 
/var/log/nginx  # 默认日志文件      
root@8657715d04a5:/# find / -name nginx.conf
/etc/nginx/nginx.conf  # 编辑该配置文件哦

复制前端文件到容器中

[root@localhost ~]# docker cp  /home/summer/nginx/html 8657715d04a5:/usr/share/nginx/html

处理默认配置

root@8657715d04a5:/etc/nginx/conf.d# pwd
/etc/nginx/conf.d
root@8657715d04a5:/etc/nginx/conf.d# mv default.conf default

编辑定制nginx.conf

root@8657715d04a5:/# vim /etc/nginx/nginx.conf

重新加载

root@8657715d04a5:/usr/sbin# ./nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
root@8657715d04a5:/usr/sbin# ./nginx -s reload
