RHEL/CentOS 7/6-da Nginx üçin SSL şahadatnamasyny şifrlemek bilen HTTPS gurmak

Nginx.conf-a aşakdaky blok böleklerini goşuň:

ssl_dhparam /etc/nginx/ssl/dhparams.pem;
ssl_session_timeout 30m;
ssl_session_cache shared:SSL:10m;
ssl_buffer_size 8k;
add_header Strict-Transport-Security max-age=31536000;

15. Üýtgeşmeleri ulanmak we öňki netije keşini ýokarda görkezilen baglanyşykdan arassalamak bilen Nginx hyzmatyny täzeden açyň.

# systemctl restart nginx
# service nginx restart

5-nji ädim: Nginx mugt SSL şahadatnamalaryny şifrlemäge mümkinçilik berýär

16. Geliň, şifrlemek CA 90 günüň dowamynda mugt SSL/TLS şahadatnamalaryny çykaralyň. Şahadatnamalar, aşakdaky buýruklary bermek bilen, web serweriňizi saklamazdan, webroot plaginini ulanyp, el bilen täzelenip we ulanylyp bilner:

# ./letsencrypt-auto certonly -a webroot --agree-tos --renew-by-default --webroot-path=/usr/share/nginx/html/ -d yourdomain.tld -d www.yourdomain.tld
# systemctl reload nginx

Aboveokardaky buýrugy ýerine ýetireniňizde, Nginx kök beýany bilen görkezilen web serwer resminama köküne gabat gelmek üçin webroot-path çalyşýandygyňyzy anyklaň.

17. Şahadatnamanyň möhleti gutarmanka awtomatiki täzelenmek üçin/usr/local/bin/katalogynda github erikaheidi-den bu baş skript dörediň we aşakdaky mazmuny goşuň (Nginx sazlamasyny görkezmek üçin birneme üýtgedilen skript).

# vi /usr/local/bin/cert-renew

cert-update faýlyna aşakdaky setirleri goşuň.

#!/bin/bash

webpath='/usr/share/nginx/html/'
domain=$1
le_path='/opt/letsencrypt'
le_conf='/etc/letsencrypt'
exp_limit=30;

get_domain_list(){
        certdomain=$1
        config_file="$le_conf/renewal/$certdomain.conf"

        if [ ! -f $config_file ] ; then
                echo "[ERROR] The config file for the certificate $certdomain was not found."
                exit 1;
        fi

        last_char=$(echo "${domains}" | awk '{print substr($0,length,1)}')

        if [ "${last_char}" = "," ]; then
                domains=$(echo "${domains}" |awk '{print substr($0, 1, length-1)}')
        fi

        echo $domains;

        exit 1;

        echo "[ERROR] certificate file not found for domain $domain."
        exit 1;

echo "Checking expiration date for $domain..."

if [ "$days_exp" -gt "$exp_limit" ] ; then
        echo "The certificate is up to date, no need for renewal ($days_exp days left)."
        exit 0;
else
        echo "The certificate for $domain is about to expire soon. Starting renewal request..."
        domain_list=$( get_domain_list $domain )

        echo "Reloading Nginx..."
sudo systemctl reload nginx
        echo "Renewal process finished for domain $domain"
        exit 0;
fi

18. Nginx resminama köküňize gabat gelmek üçin skriptiň başyndan $webpath üýtgeýjisini çalyşyň. Scriptazuwyň ýerine ýetirilýändigine we aşakdaky buýruklary bermek bilen ulgamyňyza bc kalkulýatorynyň gurnalandygyna göz ýetiriň.

# chmod +x /usr/local/bin/cert-renew
# yum install bc

Aşakdaky buýrugy bermek bilen skriptiňizi domeniňize synap bilersiňiz:

# /usr/local/bin/cert-renew yourdomain.tld

19. Netijede, şahadatnamanyň täzeleniş amalyny awtomatiki usulda işletmek üçin, şahadatnamanyň möhleti gutarýança 30 günüň dowamynda täzelenmek üçin her hepde skripti ýerine ýetirmek üçin täze bir iş goşuň.

# crontab -e

Faýlyň aşagyna aşakdaky setiri goşuň.

@weekly  /usr/local/bin/cert-renew your_domain.tld >> /var/log/your_domain.tld-renew.log 2>&1

Bu hemmesi! Indi Nginx serweri, web sahypaňyzda mugt SSL/TLS Geliň şifrlemek şahadatnamasy bilen ygtybarly web mazmunyny berip biler.
