Nginx配置解析

#运行用户，默认即是nginx，可不设置
#user  nobody;
#nginx进程,一般设置为和cpu核数一样
worker_processes  1;
 #;单个后台worker process进程的最大并发链接数

安装命令解析

docker pull nginx:1.12.2
docker run -itd --restart=unless-stopped -v /etc/localtime:/etc/localtime -v /etc/timezone:/etc/timezone -p $1:80:80 --name nginx -v /data/yjs/nginx/html:/usr/share/nginx/html -v /data/yjs/nginx/logs:/var/log/nginx -v /data/yjs/nginx/conf/nginx.conf:/etc/nginx/nginx.conf nginx:1.12.2

解析后：

#拉取版本1.12.2的nginx
docker pull nginx:1.12.2   
#-i: 以交互模式运行容器，通常与 -t 同时使用；
#-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；
#-d: 后台运行容器，并返回容器ID；
#通过--restart选项，可以设置容器的重启策略，以决定在容器退出时Docker守护进程是否重启刚刚退出的容器。
#unless-stopped，在容器退出时总是重启容器，但是不考虑在Docker守护进程启动时就已经停止了的容器
docker run -itd --restart=unless-stopped  
# 同步时区
-v /etc/localtime:/etc/localtime 
-v /etc/timezone:/etc/timezone 
#开放端口，并映射到本地的 80 端口。
-p $1:80:80 --name nginx 
#挂载到绝对路径下
-v /data/yjs/nginx/html:/usr/share/nginx/html 
-v /data/yjs/nginx/logs:/var/log/nginx 
-v /data/yjs/nginx/conf/nginx.conf:/etc/nginx/nginx.conf nginx:1.12.2

注意事项：

• 配置路径要为绝对路径
• 上面的域名要想可以访问，要使用域名信息备案过的域名方可
