安裝命令解析

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

解析後：

#拉取版本1.12.2的nginx
docker pull nginx:1.12.2   
#-i: 以交互模式運行容器，通常與 -t 同時使用；
#-t: 爲容器重新分配一個僞輸入終端，通常與 -i 同時使用；
#-d: 後臺運行容器，並返回容器ID；
#通過--restart選項，可以設置容器的重啓策略，以決定在容器退出時Docker守護進程是否重啓剛剛退出的容器。
#unless-stopped，在容器退出時總是重啓容器，但是不考慮在Docker守護進程啓動時就已經停止了的容器
docker run -itd --restart=unless-stopped  
# 同步時區
-v /etc/localtime:/etc/localtime 
-v /etc/timezone:/etc/timezone 
#開放端口，並映射到本地的 80 端口。
-p $1:80:80 --name nginx 
#掛載到絕對路徑下
-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

注意事項：

• 配置路徑要爲絕對路徑
• 上面的域名要想可以訪問，要使用域名信息備案過的域名方可
