1、安装所需依赖
yum -y install pcre pcre-devel gcc openssl openssl-devel zlib zlib-devel（pcre： 包括 perl 兼容的正则表达式库
openssl： 支持安全传输协议https(和财务有关系的请求会走的协议)
创建运行用户、组
useradd -M -s /sbin/nologin nginx
2、上传安装包到local下
解压
tar -zxvf nginx-1.20.2.tar.gz切换到解压目录下
cd /usr/local/nginx-1.20.2
执行安装命令
./configuremake&&make install3、切换到安装目录
cd /usr/local/nginx/conf找到nginx.conf文件，需修改端口
vim nginx.confserver {listen 80;（默认时80端口需要更改）server_name localhost;
4、启动nginx服务
cd /usr/local/nginx/sbin启动命令./nginx
5.查看nginx是否启动成功
ps -ef|grep nginx
6、设置防火墙，开放8066端口
查看防火墙是否开放过此端口
firewall-cmd --list-all
开放端口
firewall-cmd --zone=public --add-port=8066/tcp --permanent一定要重启防火墙
firewall-cmd --reload7、设置开机自动启动
切换到/lib/systemd/system/目录，创建nginx.service文件vi nginx.service
# cd /lib/systemd/system/
# vim nginx.service文件内容如下：[Unit]
Description=nginx
After=network.target [Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx reload
ExecStop=/usr/local/nginx/sbin/nginx quit
PrivateTmp=true [Install]
WantedBy=multi-user.target退出并保存文件，执行systemctl enable nginx.service 使nginx开机启动systemctl start nginx.service 启动nginxsystemctl stop nginx.service 结束nginxsystemctl restart nginx.service 重启nginx##############################nginx.conf配置文件############################
