1.简介
2.特性
二.nginx安装
1.rpm包方式
(1)下载扩展源
(2)安装扩展rpm包,nginx -V查看配置参数,后面源码安装时要用到
2.源码方式
(1)建议提前下好所需要的部分包
(2)下载tar.gz包
(3)建议将包解压到/usr/local/src下,执行configure文件
(4)安装好上面需要的包,继续执行第一步
(5)一直到这步,configure文件就执行好了
(6)make,make install编译安装

一.nginx简介
1.简介
nginx是一个轻量级的网页服务器、方向代理服务器和电子邮件代理服务器,具有配置灵活、静态资源高并发、系统资源占用少、拥有缓存服务等优点。
2.特性
(1)对于静态资源,高速,高并发访问和缓存,支持htto相应速率限制
(2)支持使用反向代理加速,缓存数据
(3)可实现负载均衡和节点健康检查
(4)支持FastCGI,SCGI,Memcached Servers等服务的急速和缓存
(5)支持基于域名、端口、IP的虚拟主机站点代理,可以进行访问控制
(6)支持Keep-alive和pipelined连接
(7)在代码上线时可以平滑重启,不影响基本功能
(8)可以对日志进行格式自定义、临时缓冲、快速轮训和rsyslog处理
(9)支持信号控制nginx进程
(10)支持url重写和正则表达式匹配
(11)支持PUT、DELETE、MKCOL、COPY、MOVE等特殊http请求方法
(12)支持邮件服务代理
二.nginx安装
前提要卸载或关闭apache的httpd
[root@localhost ~]# systemctl stop httpd
[root@localhost ~]# systemctl status httpd
● httpd.service - The Apache HTTP ServerLoaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled)Active: inactive (dead)Docs: man:httpd(8)man:apachectl(8)
1.rpm包方式
(1)下载扩展源
(2)安装扩展rpm包,nginx -V查看配置参数,后面源码安装时要用到
[root@localhost ~]# yum install https://nginx.org/packages/centos/7Server/x86_64/RPMS/nginx-debuginfo-1.22.0-1.el7.ngx.x86_64.rpm
