什么是Nginx
Nginx是一个HTTP和反向代理服务器,一个邮件代理服务器和一个通用的TCP / UDP代理服务器,最初由Igor Sysoev编写。很长一段时间以来,它一直在许多负载很重的俄罗斯网站上运行,包括 Yandex, Mail.Ru, VK和 Rambler。据Netcraft称,nginx 在2019年3月服务或代理了 26.20%最繁忙的网站。
Nginx能干什么
Nginx具体能干嘛可以参考下以下博客
https://www.cnblogs.com/wcwnina/p/8728391.html
Nginx安装
- 安装编译工具和库文件
1
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
安装成功后
- 安装 PCRE
安装PCRE是为了让 Nginx 支持 Rewrite 功能
安装前请确保安装了wget(如果没有的话请输入以下命令安装wget)1
yum install weget
1.下载 PCRE 安装包,下载地址: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz1
2[root@name /]# cd /usr/local/src/
[root@name src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
2.解压安装包1
[root@name src]# tar zxvf pcre-8.35.tar.gz
3.进入安装包目录1
[root@name src]# cd pcre-8.35
4.编译安装1
2[root@name pcre-8.35]# ./configure
[root@name pcre-8.35]# make && make install
5.查看pcre版本1
[root@name pcre-8.35]# pcre-config --version
- 安装Nginx
1.下载 Nginx,下载地址:http://nginx.org/download/nginx-1.6.2.tar.gz1
2[root@bogon /]# cd /usr/local/src/
[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
2.解压安装包1
[root@name src]# tar zxvf nginx-1.6.2.tar.gz
3.进入安装包目录1
[root@name src]# cd nginx-1.6.2
4.编译安装1
2[root@name nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@name nginx-1.6.2]# make && make install
5.查看pcre版本1
2[root@name pcre-8.35]# /usr/local/webserver/nginx/sbin/nginx -v

Nginx配置
创建Nginx运行使用的用户uername
1
2[root@name /]# /usr/sbin/groupadd uername
[root@name src]# /usr/sbin/useradd -g uername uername配置前我们需要了解一些vim的基础命令(因为我们是用vim对配置文件进行编辑)
vim命令可以参考以下博客:
https://blog.csdn.net/sumword_/article/details/53011463?utm_source=blogxgwz1- 配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
