Check your PATH (and lib path). When you use archive.sh, you're using php-cli -- depending on your PATH, this could be Zend Server or the pre-built php binaries that came with your original CentOS install.

Where can directly set the path to pdo_mysql, which would archive.sh saw him?

That's not what I said.

The problem is that archive.sh is finding your old php binary instead of the Zend Server version. Check your PATH. You might have to do something like editing your PATH, customizing archive.sh for your environment, or creating a soft-link, eg

ln -s /usr/local/zend/bin/php-cli /usr/bin/php

Write:

for TEST_PHP_BIN in php5 php; do
      if which /usr/local/zend/bin/php >/dev/null 2>/dev/null; then
        PHP_BIN=`/usr/local/zend/bin/php`
        break
      fi
    done

But it became an error:

The mysql driver is not currently installed

Mysql - installed, and - works fine.:

rpm-qa | grep mysql
libdbi-dbd-mysql-0.8.1a-1.2.2
mysql-5.0.77-4.el5_4.1
mysql-server-5.0.77-4.el5_4.1
mysql-5.0.77-4.el5_4.1
mysql-devel-5.0.77-4.el5_4.1
mysql-bench-5.0.77-4.el5_4.1
mysql-connector-odbc-3.51.26r1127-1.el5
mysql-devel-5.0.77-4.el5_4.1

What to do? What data are needed to solve this problem?
