在上一篇中介绍了Nginx依赖组件的安装过程：Nginx安装部署（一）
本篇主要内容为Nginx本身在Linux环境下的安装部署步骤。
Nginx下载
访问Nginx官网：http://nginx.org/en，右边栏点击download进入下载页

[root@localhost local]# wget http://nginx.org/download/nginx-1.16.0.tar.gz
[root@localhost local]# tar -xzvf nginx-1.16.0.tar.gz
[root@localhost local]# cd nginx-1.16.0
// --prefix是指定nginx安装的目录，--with-xx指定了pcre和zlib的路径
[root@localhost nginx-1.16.0]# ./configure --prefix=/usr/local/nginx \
> --with-pcre=/usr/local/pcre-8.43 \
> --with-zlib=/usr/local/zlib-1.2.11
Nginx检查环境变量结束后输出以下信息：
Configuration summary
+ using PCRE library: /usr/local/pcre-8.43
+ OpenSSL library is not used
+ using zlib library: /usr/local/zlib-1.2.11
nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx modules path: "/usr/local/nginx/modules"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"
OpenSSL在使用https时才会用到，所以没有指定路径。如果用到openssl，照着例子套就行。
nginx开头的文字建议记住，这些信息告诉了我们Nginx的安装目录，Nginx进程信息，http的访问日志等，使用过程中经常会用到。
// 执行编译和安装
make && make install
cd /usr/local/nginx/sbin
[root@localhost sbin]# ll

-rwxr-xr-x. 1 root root 3957496 5月 23 22:06 nginx
[root@localhost sbin]# ./nginx
// 查看nginx状态
[root@localhost sbin]# ./nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost sbin]# ps -ef | grep nginx
root 90250 1 0 22:07 ? 00:00:00 nginx: master process ./nginx
nobody 90251 90250 0 22:07 ? 00:00:00 nginx: worker process
root 90254 79852 0 22:10 pts/1 00:00:00 grep --color=auto nginx
[root@localhost sbin]# netstat -nlp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 90250/nginx: master
可以看到Nginx默认绑定80端口，如果nginx起不来，可以查看日志检查是否端口已绑定。已绑定端口可以执行
service httpd stop
关闭端口。更好的方式是修改nginx的监听端口,Nginx配置文件位于/usr/local/nginx/conf目录下的nginx.conf
vi nginx.conf

将80端口修改成你期望的端口。
重启Nginx
[root@localhost sbin]# ./nginx -s reload

此时access.log文件有字节，开始记录访问日志：
[root@localhost sbin]# cd ../logs/
[root@localhost logs]# ll
