Nginx学习入门一
1. 基本介绍
Nginx是高性能的http/https和反向代理服务器，特点是占用内存少，处理高并发能力强大。有报告表明Nginx能够支持50000个并发连接数。
2. 安装
安装环境：CentOS7
1) 安装gcc-c++
yum install gcc-c++
2) 安装pcre
wget http://downloads.sourceforge.net/project/pcre/pcre/8.44/pcre-8.44.tar.gz
tar -xvf pcre-8.44.tar.gz
./configigure
make
make install
3) 安装openssl、zlib、gcc
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
4) 安装nginx
官网下载：http://nginx.org/
tar -xvf nginx-1.16.1.tar.gz
./configigure
make
make install
3. 命令
nginx安装目录：/usr/local/nginx
命令行操作nginx前，先cd到/usr/local/nginx/sbin
查看版本号 ./nginx -v
启动nginx ./nginx
停止nginx ./nginx -s stop
重加载nginx ./nginx -s reload
4. 访问nginx主页
centos防火墙默认关闭80端口，外网需要访问到该服务，需要开放对应端口号
查看防火墙开放全部端口号
firewall-cmd --list-all
添加端口号
firewall-cmd --add-service=http --permanent
firewall-cmd --add-port=80/tcp --permanent
重启防火墙
Firewall-cmd --reload
