PHP installation pdo extension
This article only adds pdo extensions to php installed through compilation, and does not try to practice when yum installs php.
1. Install the PDO component
Unzip the php installation package, enter the pdo component directory, create the PDO plug-in module through phpize, specify the php-config path, and install pdo.
cd /usr/local/download/php-5.6.23/ext/pdo phpize ./configure --with-php-config=/usr/local/app/php/bin/php-config make & make install
2. Install the PDO_MYSQL component
Enter the pdo_myqsl component directory, create a php plug-in module through phpize, specify the php-config path and mysql installation path, and install pdo_mysql.
cd /usr/local/download/php-5.6.23/ext/pdo_mysql phpize ./configure --with-php-config=/usr/local/app/php/bin/php-config --with-pdo-mysql=/usr/ make & make install
There are some pitfalls in specifying the mysql path here, because I installed mysql using yum. The mysql path I found through the find / -name mysql and service mysqld status commands were not correct, and an error was prompted.
#提示msyql没找到 checking for mysql_config... not found configure: error: Unable to find your mysql installation #提示没有mysql_query configure: error: mysql_query missing!?
Later I saw that others had successfully installed using --with-pdo-mysql=/usr/, so I tried the same, and it worked.
If you downloaded the installation package from http://pecl.php.net/package/PDO_MYSQL, decompress the installation file and follow the command in step 2.
3. Add extension
After the pdo component is successfully installed, the output message will include the installation path, such as:
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/
Edit the php configuration file php.ini, find the line; extension_dir = “./”, and remove the comment.
And modify the path to extension_dir = "/usr/local/php/lib/php/extensions/".
Find extension=, add the reference module:
extension=pdo.so extension=pdo_mysql.so
Finally restart php, you can view the pdo component information through phpinfo(). Here you need to make sure that the configuration file loaded by php is the one you modified.
