1安裝依賴包javascript

yum install -y wget  
yum install -y vim-enhanced  
yum install -y make cmake gcc gcc-c++  

yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel

2上傳包
php

解壓縮
[root@xiniu nginx]# ls
nginx-1.10.2.tar.gz
[root@xiniu nginx]# tar -zxvf nginx-1.10.2.tar.gz

進行configure配置

[root@xiniu nginx]# ls
nginx-1.10.2  nginx-1.10.2.tar.gz
[root@xiniu nginx]# cd nginx-1.10.2
[root@xiniu nginx-1.10.2]# ./configure --prefix=/usr/local/nginx

3編譯安裝css

執行
[root@xiniu nginx-1.10.2]# make && make install
make -f objs/Makefile
make[1]: 進入目錄「/usr/local/nginx/nginx-1.10.2」
cc -c -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g  -I src/core -I src/event -I src/event/modules -I src/os/unix -I ob
js \    -o objs/src/core/nginx.o \

.........
    '/usr/local/nginx/conf/scgi_params.default'
test -f '/usr/local/nginx/conf/nginx.conf' \
    || cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf'
cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf.default'
test -d '/usr/local/nginx/logs' \
    || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/logs' \
    || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/html' \
    || cp -R html '/usr/local/nginx'
test -d '/usr/local/nginx/logs' \
    || mkdir -p '/usr/local/nginx/logs'
make[1]: 離開目錄「/usr/local/nginx/nginx-1.10.2」

4檢查nginx是否已經正常啓動，看到以下信息說明正常啓動html

[root@xiniu nginx-1.10.2]# /usr/local/nginx/sbin/nginx
[root@xiniu nginx-1.10.2]# ps -ef | grep nginx
root       7622      1  0 15:49 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody     7623   7622  0 15:49 ?        00:00:00 nginx: worker process
root       7625   2865  0 15:49 pts/1    00:00:00 grep --color=auto nginx
[root@xiniu nginx-1.10.2]#

測試
輸入：
linux的IP:80
java

nginx配置
在nginx目錄下進入conf目錄，該目錄下有個nginx.conf文件，這是nginx最重要的配置文件node
