sudo yum install openssl openssl-devel pcre pcre-devel zlib zlib-devel gcc gcc-c++gcc: 一个开源的编译器集合，用于处理各种各样的语言，其中就包含了C语言
pcre:正则表达式库
zlib:压缩算法,gzip压缩
openssl：开放源代码的ssl软件库包

tar -zxvf nginx-1.20.2.tar.gz进入nginx-1.20.2
cd nginx-1.20.2编译
./configure // 默认编译在/usr/local/nginx./configure --prefix=/etc/nginx --with-http_ssl_module
#后面加上了nginx_limit_speed_module 模块
./configure --prefix=/etc/nginx --with-http_ssl_module --add-module=/home/nginx_limit_speed_module这种方式和简单的安装配置不同的地方在第一步，通过./configure来对编译参数进行设置，需要我们手动来指定。那么都有哪些参数可以进行设置，接下来我们进行一个详细的说明。
PATH:是和路径相关的配置信息
with:是启动模块，默认是关闭的
without:是关闭模块，默认是开启的
我们先来认识一些简单的路径配置已经通过这些配置来完成一个简单的编译：
--prefix=PATH
指向Nginx的安装目录，默认值为/usr/local/nginx--sbin-path=PATH
指向(执行)程序文件(nginx)的路径,默认值为<prefix>/sbin/nginx--modules-path=PATH
指向Nginx动态模块安装目录，默认值为<prefix>/modules--conf-path=PATH
指向配置文件(nginx.conf)的路径,默认值为<prefix>/conf/nginx.conf--error-log-path=PATH
指向错误日志文件的路径,默认值为<prefix>/logs/error.log--http-log-path=PATH
指向访问日志文件的路径,默认值为<prefix>/logs/access.log--pid-path=PATH
指向Nginx启动后进行ID的文件路径，默认值为<prefix>/logs/nginx.pid--lock-path=PATH
指向Nginx锁文件的存放路径,默认值为<prefix>/logs/nginx.lock要想使用可以通过如下命令
./configure --prefix=/usr/local/nginx \
--sbin-path=/usr/local/nginx/sbin/nginx \
--modules-path=/usr/local/nginx/modules \
--conf-path=/usr/local/nginx/conf/nginx.conf \
--error-log-path=/usr/local/nginx/logs/error.log \
--http-log-path=/usr/local/nginx/logs/access.log \
--pid-path=/usr/local/nginx/logs/nginx.pid \
--lock-path=/usr/local/nginx/logs/nginx.lock安装
make & make install命令
sbin下的nginx命令默认是指定/etc/nginx/conf/nginx.conf，我的nginx.conf路径不同需要单独指定
#启动
./nginx -c /etc/nginx/nginx.conf
#重载
./nginx -s reload
./nginx -c /etc/nginx/nginx.conf -s reload
#杀掉nginx
./nginx -s quit
./nginx -c /etc/nginx/nginx.conf -s quit
#测试

WantedBy=multi-user.target重新加载 systemd 配置文件
systemctl daemon-reload设置开机自启动
systemctl start nginx // 开启
systemctl stop nginx // 停止
systemctl restart nginx // 重启
systemctl reload nginx // 重新加载配置文件
systemctl status nginx // 状态
systemctl enable nginx // 开机启动
systemctl disable nginx // 关闭开机启动系统环境
修改/etc/profile文件
在最后一行添加
export PATH=$PATH:/usr/local/nginx/sbin生效
