//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

--http-log-path=/var/log/nginx/access.log \
--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

升级、添加echo功能

//查看nginx安装了哪些功能

//下载echo功能的包和nginx的包
[root@localhost ~]# yum -y install git
[root@localhost ~]# wget https://nginx.org/download/nginx-1.20.1.tar.gz
[root@localhost ~]# git clone https://github.com/openresty/echo-nginx-module.git
[root@localhost ~]# tar xf nginx-1.20.1.tar.gz 
[root@localhost ~]# ls
anaconda-ks.cfg  echo-nginx-module  nginx-1.20.1  nginx-1.20.1.tar.gz

//升级nginx
[root@localhost ~]# cp /usr/local/nginx/sbin/nginx{,-bak}
[root@localhost ~]# cd nginx-1.20.1/

[root@localhost nginx-1.20.1]# vim /usr/local/nginx/conf/nginx.conf
        location /test {
            echo "test";
        }
        
[root@localhost nginx-1.20.1]# nginx -t
