So, there are results of my experiment:
- adding /usr/local/mysql/lib to ld.so.conf solve problem with libmysqlclient.so
- extension mysql.so was deprecated and deleted from php7, stay only mysqli.so and pdo_mysql.so
- libgd 2.2.4 works correct both php5 and php7
- apache2.2 not launch with apr-utils ver 1.5.4 and needed older version, crashing with child pid XXXX exit signal Segmentation fault (11)
Unfortunately one of my php-project required mysql-extension, so i have to stay on php5, while not to fix it.
Thanks for help!
