Nginx服务器安装证书并启用SSL(acme.sh)

本文主要是介绍Nginx服务器安装证书并启用SSL(acme.sh)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前提

1. 您已购置vps服务器，例如阿里云全球站ecs、AWS EC2、Azure VM、GCP Compute等
2. 安全组已开启80、443端口，且访问源设置为0.0.0.0/0
3. 域名已设置A记录指向当前操作服务器，若您使用aws ec2，有公有 IPv4 DNS，可供使用

安装Acme.sh并申请证书Step-By-Step

Ubuntu—EasyWay

cat >> install-CA.sh << EOF
#!/bin/bash
rm -rf /etc/nginx/cert/ && mkdir /etc/nginx/cert/
read -p "Enter your domain: " domain
rootDomain=\`echo $domain|cut -d '.' -f2-\`
apt -y install wget unzip socat
curl https://get.acme.sh | sh
rm -rf /usr/local/bin/acme.sh
ln -s  /root/.acme.sh/acme.sh /usr/local/bin/acme.sh
acme.sh --register-account -m admin@$rootDomain
acme.sh  --issue -d ${domain}  --standalone -k ec-256
cp /root/.acme.sh/${domain}_ecc/fullchain.cer /etc/nginx/cert/server.cert
cp /root/.acme.sh/${domain}_ecc/${domain}.key /etc/nginx/cert/server.key
acme.sh --installcert -d ${domain} --ecc  --key-file   /etc/nginx/cert/server.key   --fullchain-file /etc/nginx/cert/server.cert
systemctl start nginx
EOF

CentOS—EasyWay

cat >> install-CA.sh << EOF
#!/bin/bash
rm -rf /etc/nginx/cert/ && mkdir /etc/nginx/cert/
read -p "Enter your domain: " domain
rootDomain=\`echo $domain|cut -d '.' -f2-\`
yum -y install wget unzip socat
curl https://get.acme.sh | sh
rm -rf /usr/bin/acme.sh
ln -s  /root/.acme.sh/acme.sh /usr/bin/acme.sh
acme.sh --register-account -m admin@$rootDomain
acme.sh  --issue -d ${domain}  --standalone -k ec-256
cp /root/.acme.sh/${domain}_ecc/fullchain.cer /etc/nginx/cert/server.cert
cp /root/.acme.sh/${domain}_ecc/${domain}.key /etc/nginx/cert/server.key
acme.sh --installcert -d ${domain} --ecc  --key-file   /etc/nginx/cert/server.key   --fullchain-file /etc/nginx/cert/server.cert
systemctl start nginx
EOF

nginx配置设置—以centos为例

修改nginx.conf的内容

取消Settings for a TLS enabled server下的注释内容

    server {listen       443 ssl http2;listen       [::]:443 ssl http2;server_name  YourDomain;root         /usr/share/nginx/html;ssl_certificate "/etc/nginx/cert/server.cert";ssl_certificate_key "/etc/nginx/cert/server.key";ssl_session_cache shared:SSL:1m;ssl_session_timeout  10m;ssl_ciphers DEFAULT;# This is default SSL_ciphers setting,if you get error,you can change it like me,set DEFAULT#ssl_ciphers PROFILE=SYSTEM;ssl_prefer_server_ciphers on; # Load configuration files for the default server block.include /etc/nginx/default.d/*.conf;error_page 404 /404.html;location = /40x.html {}   error_page 500 502 503 504 /50x.html;location = /50x.html {}   }   

Trouble Shooting

SSL_CTX_set_cipher_list:no cipher match

报错信息

[emerg] 11926#11926: SSL_CTX_set_cipher_list("PROFILE=SYSTEM") failed (SSL: error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match)

Solution

将nginx.config默认的ssl_ciphers PROFILE=SYSTEM;设置为ssl_ciphers DEFAULT;
重启nginx即可
