1、新增使用者admin，新增許可權到wheel組

adduser admin
passwd admin
gpasswd -a admin wheel

參考：https://www.digitalocean.com/community/tutorials/initial-server-setup-with-centos-7

2、更新yum源

參考：http://help.aliyun.com/knowledge_detail.htm?knowledgeId=5974184

yum update 

3、安裝nginx

yum install nginx 

配置檔案路徑：/etc/nginx

4、systemctl 指令

5、Java環境安裝

wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie;"  http://download.oracle.com/otn-pub/java/jdk/8u45-b14/jdk-8u45-linux-x64.rpm

rpm -ivh jdk-8u45-linux-x64.rpm

/usr/java/jdk1.8.0_45

vi /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_45
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar
 
:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

source /etc/profile

6、Tomcat的安裝和配置

cd /usr

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.23/bin/apache-tomcat-8.0.23.tar.gz
tar -xzvf apache-tomcat-8.0.23.tar.gz 

安裝目錄：/usr/apache-tomcat-8.0.23

配置：
<Host name="localhost"
 
  appBase="/home/admin/webapps" unpackWARs="true" autoDeploy="true">

    <Context path="/" docBase="application" reloadable="true"/>

</Host>

7、一些便捷操作

ln -s /usr/apache-tomcat-8.0.23/bin/startup.sh /home/admin/bin/start_tomcat.sh
ln -s /usr/apache-tomcat-8.0.23/bin/shutdown.sh /home/admin/bin/stop_tomcat.sh

ln -s /usr/apache-tomcat-8.0.23/logs /home/admin/logs/tomcat

nginx_status.sh:

#!/bin/sh
exec /bin/systemctl status  nginx.service

restart_nginx.sh：

#!/bin/sh
exec /bin/systemctl restart  nginx.service

nginx_stop.sh:

#!/bin/sh
exec /bin/systemctl stop  nginx.service

8、nginx配置

/etc/nginx/nginx.conf:

user  nginx;
worker_processes  4;

error_log  /home/admin/logs/nginx/error.log;

pid        /run/nginx.pid;


events {
    worker_connections  10240;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    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   /home/admin/logs/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;

    index   index.html index.htm;

    upstream tomcat_server{
       server 127.0.0.1:8080 weight=1;
    }

    include /etc/nginx/conf.d/*.conf;
}

/etc/nginx/conf.d/www.nzaom.com.conf:

server {
    listen       80 default_server;
    server_name  www.nzaom.com nzaom.com nzaom.hehuyou.com;

    charset utf-8;
    access_log  /home/admin/logs/nginx/access.log  main;

    location / {
        root /home/admin/webapps;
        proxy_pass http://tomcat_server;
        proxy_set_header    Host $host;
        proxy_set_header    X-Real-IP $remote_addr;
        proxy_set_header    REMOTE-HOST $remote_addr;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    error_page  404              /error.htm;

    # redirect server error pages to the static page /50x.html
    #
}

以上這些都是基礎配置，相關引數還待優化。當然，進入了Java的世界，你永遠少不了更復雜的配置，這些將會在日後的開發過程中遇到。
