Docker 笔记二：安装Nginx

docker pull nginx

I’d like to install nginx as a load balance server.

http {
include       mime.types;
default_type  application/octet-stream;
#定义日志格式
#log_format  main  '$remote_addr - $remote_user [$time_local] $request '
#                  '"$status" $body_bytes_sent "$http_referer" '
#                  '"$http_user_agent" "$http_x_forwarded_for"';
#access_log  off;
access_log  logs/access.log;
client_header_timeout  3m;
client_body_timeout    3m;
send_timeout           3m;
client_header_buffer_size    1k;
large_client_header_buffers  4 4k;
sendfile        on;
tcp_nopush      on;
tcp_nodelay     on;
#keepalive_timeout  75 20;
include    gzip.conf;
upstream localhost {
#根据ip计算将请求分配各那个后端tomcat，许多人误认为可以解决session问题，其实并不能。
#同一机器在多网情况下，路由切换，ip可能不同
#ip_hash;
server localhost:18081;
server localhost:18080;
}
server {
listen       80;
server_name  localhost;
location / {
proxy_connect_timeout   3;
proxy_send_timeout      30;
proxy_read_timeout      30;
proxy_pass http://localhost;
}
}

I have crossed the oceans of time, to find you

I have crossed the oceans of time, to find you

对白台词，煽情的，经典的，听得也不少
很多早就过耳既忘
可是，这一句，却常常响起在耳畔
抑或早已铭刻于心
“我穿越了时间的瀚海来寻找你……”
时间，海洋，爱情，四百年，等待，轮回，
一幅幽远，广阔，空旷的场景
如果用时间来丈量爱情，四百年够不够长？
如果用空间来丈量爱情，无边的海洋够不够宽广？

我却可以将时空的阻碍一一跨越，
纵使灵魂坠入无边的深渊
纵使绝望与痛苦的阴风霾雨要将我吞噬
只是,只是为了找到你

Docker 笔记一：安装Tomcat

 

docker pull tomcat

Run the default Tomcat server (CMD ["catalina.sh", "run"]):

$ docker run -it --rm tomcat:8.0

You can test it by visiting http://container-ip:8080 in a browser or, if you need access outside the host, on port 8888:

$ docker run -it --rm -p 8888:8080 tomcat:8.0

You can then go to http://localhost:8888 or http://host-ip:8888 in a browser.

The default Tomcat environment in the image for versions 7 and 8 is:

CATALINA_BASE:   /usr/local/tomcat
CATALINA_HOME:   /usr/local/tomcat
CATALINA_TMPDIR: /usr/local/tomcat/temp
JRE_HOME:        /usr
CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

The default Tomcat environment in the image for version 6 is:

CATALINA_BASE:   /usr/local/tomcat
CATALINA_HOME:   /usr/local/tomcat
CATALINA_TMPDIR: /usr/local/tomcat/temp
JRE_HOME:        /usr
CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar

The configuration files are available in /usr/local/tomcat/conf/. By default, no user is included in the “manager-gui” role required to operate the “/manager/html” web application. If you wish to use this app, you must define such a user in tomcat-users.xml.

 

If you want to map local file into the docker image, you can type following command with the parameter -v

docker run -p 8080:8080 -v /home/tomcat/webapps:/usr/local/tomcat/webapps -v /home/tomcat/conf:/usr/local/tomcat/conf -v /home/tomcat/work:/usr/local/tomcat/work tomcat
