  • How to Change PHP version in OpenLiteSpeed

    I installed OpenLiteSpeed on a server. The default PHP version was 7.3. I wanted PHP 7.4 on this server.

    To install PHP 7.4, run

    apt install -y lsphp74 lsphp74-apcu lsphp74-common lsphp74-curl lsphp74-dbg lsphp74-dev lsphp74-igbinary lsphp74-imagick lsphp74-imap lsphp74-intl lsphp74-ioncube lsphp74-json lsphp74-ldap lsphp74-memcached lsphp74-modules-source lsphp74-msgpack lsphp74-mysql lsphp74-opcache lsphp74-pear lsphp74-pgsql lsphp74-pspell lsphp74-redis lsphp74-snmp lsphp74-sqlite3 lsphp74-sybase lsphp74-tidy

    To change PHP version, i edited file

    vi /usr/local/lsws/conf/httpd_config.conf

    Find

    extProcessor lsphp{
    type                            lsapi
    address                         uds://tmp/lshttpd/lsphp.sock
    maxConns                        10
    env                             PHP_LSAPI_CHILDREN=10
    env                             LSAPI_AVOID_FORK=200M
    initTimeout                     60
    retryTimeout                    0
    persistConn                     1
    pcKeepAliveTimeout
    respBuffer                      0
    autoStart                       1
    path                            lsphp73/bin/lsphp
    backlog                         100
    instances                       1
    priority                        0
    memSoftLimit                    2047M
    memHardLimit                    2047M
    procSoftLimit                   1400
    procHardLimit                   1500
}

    In that, find

        path                            lsphp73/bin/lsphp

    Replace with

        path                            lsphp74/bin/lsphp

    Now restart PHP and openlitespeed

    killall -9 lsphp
systemctl restart lsws

    Now the site will use the new PHP version.

    You can install multiple PHP versions, to find other PHP versions available, run the command.

    apt-cache search lsphp

    As of 2023-01, openlitespeed image provided by AWS have PHP versions 7.4, 8.0, 8.1 and 8.2

    root@ip-172-31-22-59:~# apt-cache search lsphp | grep common
lsphp74-common - Common files for packages built from the PHP source
lsphp80-common - Common files for packages built from the PHP source
lsphp81-common - Common files for packages built from the PHP source
lsphp82-common - Common files for packages built from the PHP source
root@ip-172-31-22-59:~#

    If you need to install any other available PHP version, use the same apt install command as above, and replace lsphp74 with another version you need. For example, to install PHP 8.2

    apt install -y lsphp82 lsphp82-apcu lsphp82-common lsphp82-curl lsphp82-dbg lsphp82-dev lsphp82-igbinary lsphp82-imagick lsphp82-imap lsphp82-intl lsphp82-ioncube lsphp82-json lsphp82-ldap lsphp82-memcached lsphp82-modules-source lsphp82-msgpack lsphp82-mysql lsphp82-opcache lsphp82-pear lsphp82-pgsql lsphp82-pspell lsphp82-redis lsphp82-snmp lsphp82-sqlite3 lsphp82-sybase lsphp82-tidy

    After installing, you need to edit the OpenLiteSpeed config file to switch php version.

    OpenLiteSpeed move Swapping Directory

    By default OpenLiteSpeed use /tmp/lshttpd/swap for temp files. If your /tmp partition is small, disk may get full.

    To move OpenLiteSpeed swap partition to / partition do the following.

    mkdir -p /lswstmp/lshttpd/swap
chmod 750 /lswstmp/lshttpd
chmod 700 /lswstmp/lshttpd/swap
chown -R nobody:nobody /lswstmp/lshttpd

    Now login to OpenLiteSpeed admin interface at

    https://your-server-ip:7080/login.php

    If you don’t have user name and password, you can reset it by running command

    /usr/local/lsws/admin/misc/admpass.sh

    Once logged in, go to

    Server Configuration > General

    OpenLiteSpeed

    Under “Server Process’ section, you need to edit value of “Swapping Directory”. Default value is “/tmp/lshttpd/swap”, change it to “/lswstmp/lshttpd/swap”.

    Restart OpenLiteSpeed. You can do it using web interface or using SSH.

    systemctl restart lsws
