CentOS 7.3 x64 安装 Nginx

GCC & GCC-C++

[root@jdu4e00u53f7 ~]# yum install gcc
[root@jdu4e00u53f7 ~]# yum install gcc-c++

若未安装GCC，后续安装Nginx时会报如下错误：
./configure: error: C compiler cc is not found
若未安装GCC-C++，后续安装PCRE库时会报如下错误：
configure: error: You need a C++ compiler for C++ support.

PCRE library

[root@jdu4e00u53f7 centos]# wget https://ftp.pcre.org/pub/pcre/pcre-8.41.tar.gz
[root@jdu4e00u53f7 centos]# tar -zxf pcre-8.41.tar.gz
[root@jdu4e00u53f7 centos]# cd pcre-8.41
[root@jdu4e00u53f7 pcre-8.41]# ./configure 
[root@jdu4e00u53f7 pcre-8.41]# make
[root@jdu4e00u53f7 pcre-8.41]# make install

可在 [https://ftp.pcre.org/pub/pcre/](https://ftp.pcre.org/pub/pcre/) 查看最新版本。
若未安装PCRE库，后续安装Nginx时会报以下错误：
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option,or install the PCRE library into the system,or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

ZLIB Library

[root@jdu4e00u53f7 centos]# wget http://www.zlib.net/zlib-1.2.11.tar.gz
[root@jdu4e00u53f7 centos]# tar -zxf zlib-1.2.11.tar.gz
[root@jdu4e00u53f7 centos]# cd zlib-1.2.11
[root@jdu4e00u53f7 zlib-1.2.11]# ./configure 
[root@jdu4e00u53f7 zlib-1.2.11]# make
[root@jdu4e00u53f7 zlib-1.2.11]# make install

可在 [http://www.zlib.net/](http://www.zlib.net/) 查看最新版本。
若未安装ZLIB库，后续安装Nginx时会报以下错误：
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option,or install the zlib library into the system,or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.

Nginx

[root@jdu4e00u53f7 centos]# wget http://nginx.org/download/nginx-1.13.4.tar.gz
[root@jdu4e00u53f7 centos]# tar -zxf nginx-1.13.4.tar.gz
[root@jdu4e00u53f7 centos]# cd nginx-1.13.4
[root@jdu4e00u53f7 nginx-1.13.4]# ./configure 
[root@jdu4e00u53f7 nginx-1.13.4]# make
[root@jdu4e00u53f7 nginx-1.13.4]# make install

可在 [http://nginx.org/download/](http://nginx.org/download/) 查看最新版本。
Nginx的默认安装位置为 /usr/local/nginx 。

[root@jdu4e00u53f7 centos]# cd /usr/local/nginx/
[root@jdu4e00u53f7 nginx]# ls
conf  html  logs  sbin
[root@jdu4e00u53f7 nginx]# ./sbin/nginx 
[root@jdu4e00u53f7 nginx]# ps -ef | grep nginx
root     30325     1  0 23:47 ?        00:00:00 nginx: master process ./sbin/nginx
nobody   30326 30325  0 23:47 ?        00:00:00 nginx: worker process
root     30328 14495  0 23:47 pts/1    00:00:00 grep --color=auto nginx

当前工作路径为 /user/local/nginx 。
./sbin/nginx 启动 Nginx，默认端口为80。
修改端口号可编辑 ./conf/nginx.conf 中的"listen 80;"，如可以修改为"listen 8080;"。
     35     server {
     36         listen       8080;
     37         server_name  localhost;
     38 
     39         #charset koi8-r;
     40 
     41         #access_log logs/host.access.log main;
     42 
     43         location / {
     44             root   html;
     45             index  index.html index.htm;
     46         }
 保存退出后使用 "./sbin/nginx -s reload" 重新加载配置文件。
