1、安装所需依赖
yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel
2、创建nginx目录并下载Nginx安装包
//进入/usr/local
cd /usr/local
//创建nginx目录
mkdir nginx
//进入nginx目录
cd nginx
//下载nginx tar包
wget http://nginx.org/download/nginx-1.20.1.tar.gz
//解压tar
tar -xvf nginx-1.20.1.tar.gz
3、安装Nginx
//进入nginx目录
cd /usr/local/nginx/nginx-1.20.1
//执行命令
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-pcre --with-stream
//执行命令（如果不成功，检查yum安装的依赖是否成功）
make
//执行命令
make install
4、启动Nginx
//进入/usr/local/nginx/sbin目录，输入./nginx即可启动nginx
./nginx
//关闭nginx
./nginx -s quit 或者 ./nginx -s stop
//重启nginx
./nginx -s reload
//查看nginx进程
ps -ef|grep nginx
5、设置全局Nginx
//编辑/etc/profile
vim /etc/profile
//设置PATH
PATH=$PATH:/usr/local/nginx/sbin
export PATH
//执行命令
source /etc/profile
6、设置开机启动
//编辑
vim /etc/rc.local
//最底部增加这一行
/usr/local/nginx/sbin/nginx
