On a Cpanel server running CloudLinux, PHP Selector did not show all PHP versions.
I reinstalled EasyApache profile “CloudLinux + All PHP Options + OpCache + mod_lsapi”.
Even after installing EasyApache profile with all PHP versions, PHP 7.2 and PHP 7.4 was missing on this server.
To fix, the problem, i run
|
1 2 3 4 |
yum clean all yum install -y alt-php72* yum install -y alt-php74* yum install -y alt-php73* |
To renew SSL for site hosted in EasyEngine, run
|
1 |
ee site ssl-renew --all |
You can set a cronjob to run every month to auto renew the SSL certificates.
AlibabaCloud DirectMail is transactional email service from AlibabaCloud. It is like Amazon SES, MailGun, SendGrid etc…
They have 3 differnt mail server hostname depending on region. Unlike other SMTP providers, they allow email using port 80.

1 2 3 4 5 6 7 |
SMTP service address (China East 1): smtpdm.aliyun.com SMTP service address (Singapore): smtpdm-ap-southeast-1.aliyun.com SMTP service address (Sydney): smtpdm-ap-southeast-2.aliyun.com SMTP port: 25, 80, 465 (SSL encrypted). |
Note: Port 25 is currently disabled to maintain ECS security. If your sending application is deployed on Alibaba Cloud ECS, we recommend that you use port 80 when SSL is not checked, and use port 465 when SSL is checked. Besides, we support explict ssl/tls functionality on port 25 or 80 with “STARTTLS” smtp cmd.

MySQL 8 use caching_sha2_password as default autentication method. Many mysql clients still not support this method. If you need to use old method, you can set autentication plugin as mysql_native_password. You can also set this as default method by editing my.cnf file.

[mysqld] default_authentication_plugin=mysql_native_password |
To change a user to use mysql_native_password, run
|
1 |
ALTER USER ‘username’@’localhost’ IDENTIFIED WITH ‘mysql_native_password’ BY ‘PASSWORD_HERE’; |
if you have cloud sevrer with less disk space, it is better disable MySQL bin log as it take approx 3 GB of disk space on bitnami server.
