貌似Nginx这两年比较火，Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，并在一个BSD-like 协议下发行。由俄罗斯的程序设计师Igor Sysoev所开发，供俄国大型的入口网站及搜索引擎Rambler（俄文：Рамблер）使用。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好。

1、环境预备

nginx依赖以下模块：

(1)gzip模块需要 zlib 库

(2)rewrite模块需要 pcre 库

(3)ssl 功能需要openssl库

1.1 安装pcre：

获取pcre编译安装包，在http://www.pcre.org/上可以获取当前最新的版本

root@webank:~# cd /usr/local/
root@webank:/usr/local# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-10.20.tar.gz

2. 解压缩pcre-xx.tar.gz包

3. 进入解压缩目录，执行./configure

root@webank:/usr/local/pcre2-10.20# ./configure

4. make & make install

root@webank:/usr/local/pcre2-10.20# make
root@webank:/usr/local/pcre2-10.20# make install

1.2 安装zlib库

root@webank:/usr/local/pcre2-10.20# cd /usr/local/ 
root@webank:/usr/local# wget http://zlib.net/zlib-1.2.8.tar.gz
root@webank:/usr/local# tar -zxvf zlib-1.2.8.tar.gz 
root@webank:/usr/local# cd zlib-1.2.8 
root@webank:/usr/local/zlib-1.2.8# ./configure
root@webank:/usr/local/zlib-1.2.8# make
root@webank:/usr/local/zlib-1.2.8# make install

1.3 安装openssl

root@webank:/usr/local/zlib-1.2.8# cd /usr/local/
root@webank:/usr/local# wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
root@webank:/usr/local# tar -zxvf openssl-1.0.1c.tar.gz 
root@webank:/usr/local/openssl-1.0.1c# cd openssl-1.0.1c
root@webank:/usr/local/openssl-1.0.1c# ./config
root@webank:/usr/local/openssl-1.0.1c# make
root@webank:/usr/local/openssl-1.0.1c# make install

2.安装nginx

root@webank:/usr/local/openssl-1.0.1c# cd /usr/local/
root@webank:/usr/local# wget http://nginx.org/download/nginx-1.9.8.tar.gz
root@webank:/usr/local# tar -zxvf nginx-1.9.8.tar.gz 
root@webank:/usr/local# cd nginx-1.9.8  
root@webank:/usr/local/nginx-1.9.8# ./configure --prefix=/usr/local/nginx  --with-pcre=/usr/local/pcre2-10.20/ --with-zlib=/usr/local/zlib-1.2.8/ --with-openssl=/usr/local/openssl-1.0.1c/
root@webank:/usr/local/nginx-1.9.8#  make & make install

在最后一步make & make install的时候报错如下：

src/core/ngx_regex.h:15:18: fatal error: pcre.h: No such file or directory
compilation terminated.
make[1]: *** [objs/src/core/nginx.o] Error 1
make[1]: Leaving directory `/usr/local/nginx-1.9.8'
make: *** [build] Error 2

解决办法：apt-get install libpcre3-dev

3. 启动nginx

直接输入命令nginx即可，但是报了以下端口错误：

ubuntu@webank:/etc/init.d$ /etc/init.d/nginx start
Starting nginx: nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
