Use yum to update php, just use one command to do it:
#yum update php
But the problem is coming. After using this command, the system told me that no available code was found. Updated package. The current PHP version is only 5.2.1, and PHP has been officially updated to 5.2.6.
After some inquiries, I found out that the source of php in the original centos system is still 5.2.1, and additional sources are needed to upgrade php.
According to the introduction of foreign netizens, Binggu added additional sources:
After logging in to ssh, run the following commands in sequence:
#rpm –import http://www.jasonlitka.com /media/rpm-gpg-key-jlitka
#vi /etc/yum.repos.d/utterramblings.repo # Nano is used here in the article, but vps cannot start nano. It is also possible to use vi instead. Yes
Add the following content to the open document:
[utterramblings]
name=jason's utter ramblings repo
baseurl=http://www.jasonlitka.com/ media/el$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.jasonlitka.com/media/rpm-gpg-key-jlitka
save.
Run the following command again to complete the php upgrade
#yum update php
Similarly, run the following command to upgrade mysql
#yum update mysql
The above is the detailed content of How to upgrade PHP and MySQL in CentOS system. For more information, please follow other related articles on the PHP Chinese website!

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
