//关闭防火墙
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0

//安装依赖环境
[root@localhost ~]# yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++

[root@localhost ~]# yum -y groups mark install 'Development Tools'

//创建系统用户nginx
[root@localhost ~]# useradd -r -M -s /sbin/nologin nginx

//创建日志存放目录
[root@localhost ~]# mkdir -p /var/log/nginx
[root@localhost ~]# chown -R nginx.nginx /var/log/nginx
[root@localhost ~]# id nginx
uid=973(nginx) gid=972(nginx) 组=972(nginx)

//下载nginx

编译安装nginx
[root@localhost nginx-1.20.1]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-debug \
--with-http_ssl_module \
--with-http_realip_module \

--error-log-path=/var/log/nginx/error.log


//查看内核
[root@localhost nginx-1.20.1]# nproc
2
//使用两个内核去安装
[root@localhost nginx-1.20.1]# make -j 2
[root@localhost nginx-1.20.1]# make install

//配置环境变量
[root@localhost ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
[root@localhost ~]# source /etc/profile.d/nginx.sh


//启动nginx
[root@localhost ~]# nginx
[root@localhost ~]# ss -antl

//下载echo功能的包和nginx的包
[root@localhost ~]# yum -y install git
