我们可以使用Nginx做什么：
- web服务器
- 负载均衡和反向代理
编译Nginx所需依赖
| 依赖 | 功用 |
|---|---|
| pcre | 解决C语言中使用正则表达式的问题，rewrite模块需要 pcre 库 |
| zlib | 通用的压缩库，gzip模块需要 zlib 库 |
| openssl | 提供了丰富的加密解密的相关功能，ssl 功能需要openssl库 |
| perl | openssl的编译需要perl |
| gcc | nginx的编译需要gcc |
安装依赖
如果主机上没有以上依赖可以执行以下命令：
yum -y install gcc perl zlib pcre-devel openssl openssl-devel获得Nginx安装包
[root@centos6-1 ~]# cd /export/servers/
[root@centos6-1 servers]# wget http://nginx.org/download/nginx-1.14.0.tar.gz解压安装包
[root@centos6-1 servers]# tar -zvxf nginx-1.14.0.tar.gz编译安装
执行configure
[root@centos6-1 servers]# cd nginx-1.14.0
[root@centos6-1 nginx-1.14.0]# ./configure博主报了以下错误
./configure: error: the HTTP rewrite module requires the PCRE library.博主主机缺少PCRE依赖，现在安装
[root@centos6-1 nginx-1.14.0]# yum install pcre-devel再执行configure，结果如下

编译安装
[root@centos6-1 nginx-1.14.0]# make & make install启动Nginx
默认安装路径为：/usr/logcal/nginx
[root@centos6-1 ~]# cd /usr/local/
[root@centos6-1 local]# ll

root 101578 96782 0 17:04 pts/1 00:00:00 grep nginx可以看到nginx已经启动了，一个master进程，一个worker进程

总结
nginx已经安装成功。除了通过源码编译安装，还可以通过其他方式安装，但是源码编译可以安装最新版的nginx。在安装过程中会出现一些bug，只需要根据错误提示解决即可。当然博主这里只是介绍了最简单暴力的默认编译安装方式，如果想了解Nginx的编译安装的其他配置细节可以进入Nginx官网获取相关信息。博主后面将使用Nginx与Tomcat集成，优化web的业务处理。
