Installing SSL certificates in the domain is a necessary step to protect WordPress sites. You can now use let’s encrypt to obtain certificates for free. SSL certificate encrypts the connection between the site and the visitor browser. Hackers cannot steal or steal personal information. Usually, SSL certificates are cumbersome and expensive to install, but they change quickly. Let’s encrypt is a new open source certification body supported by top companies including automated, including WordPress, Facebook, Mozilla, chrome, Cisco and Sucuri. The goal of the project is to automate the installation of SSL certificates and create them for everyone free of charge. The
Let’s encrypt has an automated installer called certbot that can help you add certificates to your site in a matter of minutes. Certbot is currently a public beta version. There may be many changes in the official release, but the current version is stable enough to be tried on the production site. What are let’s encrypt, certbot, and SSL? SSL certificate SSL (secure socket layer) certificate was first created in 1996. It is used to encrypt the connection between websites and end users to protect the exchanged data. Data encryption refers to mixing human readable text into character and numeric strings that can only be decrypted with the private key. The
Data encryption refers to mixing human readable text into character and numeric strings that can only be decrypted with the private key. Encrypting data is the safest way to protect information over the Internet, because if the private key is hidden, no one can understand it. If a green lock is displayed in the address bar of the browser with an HTTPS prefix for accessing the site URL instead of standard HTTP, you will notice that an SSL certificate is installed on the site. The installation of the domain name SSL certificate helps protect the website. SSL certificates are installed in domains. One certificate must be installed in each domain. The
When SSL certificates are enabled, sites connected to the domain are encrypted. No matter what browser or device visitors use to access the site, as long as they use HTTPS to enter the site URL at the beginning, the connection will be encrypted and secure. Using SSL certificates on WordPress sites ensures that data and user data are unobtrusive. Because of its popularity and transparency, WordPress is a particularly big target for hackers, so it is very important to take all appropriate measures for site security. If the latest version is installed, WordPress itself is very secure. However, in order to make hacker attacks more difficult, the more obstacles to deployment, the less likely the site will be damaged. One way to add an extra layer of protection to a site is to install an SSL certificate. The
Whether it is an e-commerce site or a site that allows users to log in, SSL certificates are required for all sites that exchange information with visitors. Since all WordPress sites must have at least one user logged in, it is recommended that all WordPress sites have SSL certificates. For more information about SSL certificates and ways to help secure your site, see how WordPress uses SSL and HTTPS. The green lock and HTTPS displayed on the URL means that the SSL certificate is active. The encryptor let’s encrypt is a California public welfare legal person operated by ISRG (Internet Security Research Group), which is recognized as a tax exempt institution by the IRS. One of the approved companies can issue SSL certificates to the registered certificates. The

If CDN is enabled on the site through cloudflare, errors may occur when installing certificates. This can be prevented by temporarily interrupting cloudflare. After the certificate installation is completed, the CDN service can be restored. Restriction and location renewal condition the certificate is valid for 90 days and will not be automatically renewed, but you can use the command to automate the renewal process. There is also a limit to the number of certificates that can be installed within a specific time period. For speed limited IP addresses and 5 Certificate registrations for each domain, the limit is 500 within 3 hours, and 300 are to be verified every week. The 100 domain limit for a single certificate is also valid. In addition, each state is limited to 20 subdomains and other variants of a single domain, and each state is limited to 5 certificates of the FQDN (formal domain name) set. That is, if you want to issue certificates for up to 20 sub domains, you can issue an additional 4 certificates for the same sub domain group, unless there are more than 20 sub domains. For example, if you issued a certificate for, your site. COM, www.your-site COM, blog Your site You can issue these four certificates again. Your site COM domain name for a week. There are 20 domains in total, reaching the limit. Conversely, if you issue certificates for five domains, you can only issue three more certificates containing the same domain within a week. This is because it is the same as the 20 domains. Wildcards and ev (extended validation) SSL certificates cannot currently be used. These types of certificates may be considered in the future, but have not been developed at the time this document was created. In other words, you don’t need too many wildcard certificates, because as long as the deployment does not exceed the speed limit, you can install as many certificates as you want. Certificate location the certificate is stored in a file on the server. The cert.pem file contains the chain. Contains the certificate chain for the server. The PEM file contains all other certificates. Fullchain The PEM file contains all the certificates. The secret key is privkey. The PEM will be kept confidential to all. Otherwise, the certificate may be maliciously used and infiltrated by hackers. All of these files are located in \/etc\/letsentype\/live\/domain\/. During the update, \/etc\/letsentype\/live\/ will be updated to reflect the latest changes and files. Certbot installation certbot needs to be installed before adding certbot. Some operating systems are pre installed, but not all operating systems are pre installed. Navigate to the certbot website to determine if you need to install dependencies and find the specific commands you need. Select the web server type and operating software from the drop-down boxes to display additional information as required. On the androg certbot website, find the necessary operating system specific commands. The details are displayed below the drop-down box, so to view the commands required to install dependencies, you must scroll down slightly before you can install certbot. The command to perform this operation is listed under the dependency information on the same page of the certbot website. This page should also display the automatic renewal command. Examples of installation instructions listed. You can enter the corresponding command through SSH to install certbot. When you are finished, you can begin installing the SSL certificate. Install SSL certificate when installing a certificate, you can enter a domain in the chain. That is, a certificate can contain all the transformations of a single domain. For example, a subdomain. For all subdomains
You can create a certificate with multiple subdomains unless you create a new certificate without exceeding the speed limit described above. For example, your site. COM, www.your-site COM, blog Your site COM, store Your site COM and login. Your site You can create certificates for com. Your site COM, domain COM and example. A certificate (such as COM) cannot contain all individual sites. This setting is your site. Com below. The other items listed below will first avoid the certificates in the listed domains. https:\/\/domain.com and https:\/\/example.com An error occurred while trying to access. The browser error message shows that the certificate is invalid and prompts visitors to view that the site is unsafe. To prevent this from happening, you must ensure that all disparate domains have individually issued certificates or include file paths for each site. With this information in mind, you can proceed and install the certificate without errors. The details will be described later. In addition, when you install the first certificate, you will be prompted to enter an email and accept the terms of service. After this initial setup, you do not have to continue entering email and accepting the terms each time you install the certificate. Method 1: the control panel of some hosting companies (such as SiteGround and Dreamhost servers with basic software packages installed) contains let’s encrypt. If present, you can navigate to this path and automatically install the certificate. In addition, many platforms have basic software packages installed, making it easier to install and issue certificates. If applicable to the currently used fee system, you can confirm with the hosting company, and you should follow the instructions above to view the certbot website. The site must list the appropriate commands for installing certificates. Method 2: before installing the certificate on the stand-alone plug-in real-time site of the test site, it is recommended to use it in the test environment. The standalone certbot plug-in is fully available for this purpose. If you use this option, you must close port 80 or 443 on the server before installing the certificate. This port is used to load the site. If both ports continue to run, certbot will have an error. Port 80 is used to provide the site as the default HTTP request. Port 443 uses SSL to load the site. Therefore, port 443 can be used during certificate installation to allow visitors to continue to visit the site without HTTPS. The command to stop and restart ports depends on the type of operating software used, so you must refer to the server type documentation for this command. If the desired port is closed, you can enter one of the following commands to let certbot use the selected port– The standalone supported challenge http-01 uses port 80 — the standalone supported challenge tls-sni-01 uses port 443. Next, check the certbot website for specific methods that you need to call certbot. Rename is required to use the following certbot command. Load summary jennimckinnon\/bb1a354d9b6e7fd602e6552442f65688 the path is set in the above command, so a single certificate will be issued for each domain listed\/ The var\/www\/example Webroot directory is the path to the first two domains bundled together, \/var\/www\/other is the path to the second domain.
