我的系统是OpenEuler。

• 安装nginx

yum install -y nginx

• 启动&开机启动

systemctl start nginx
systemctl enable nginx

• 自定义conf配置文件

cat <<EOF >> /etc/nginx/conf.d/load_balancer.conf
upstream backend {ip_hash; # 防止验证码验证失败server 192.168.1.150:443;server 192.168.1.153:443;

• 检查配置文件的语法是否正确

nginx -t

• 重新加载 Nginx 配置 

nginx -s reload

• OpenSSL 生成自签名证书

openssl genpkey -algorithm RSA -out server.key -pkeyopt rsa_keygen_bits:2048openssl req -new -key server.key -out server.csr #【这一步建议绑定ip】openssl x509 -req -in server.csr -signkey server.key -out server.crt -days 36500

• 开启443端口 

firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload

• 验证 

curl -k https://192.168.1.155
