Auto-installation script for the newly deployed systems
This page generates a script for an automatic installation of operating system for AltaGrade dedicated and virtual private servers. The script incorporates all the steps on this page and referenced steps of other nodes in this book hierarchy. Introduction fields will be ignored. Make sure to properly reference steps on other nodes to get them included. To reference another node place only its nid in the source code field of any paragraph.
Newly created Virtualizor systems can pull the script by the following commands placed in the `Extra` parameter:
Additional notes:
- To install AltaOS on EU-based server, don't forget to include EU IP addresses to `Allow from` rule for in.altagrade.org in the Apache configuration file (/etc/httpd/conf/httpd.conf).
0) Check if the system is freshly installed before doing anything else, because we don't want to run the installation script twice
if [ -d /etc/webmin ]; then echo "It seems this script has already been executed on this server." echo "This script should be run only once as otherwise it will duplicate entries in number of configuration files!" exit 0 fi
1) Creating global aliases for user SSH sessions
242) Defining some variable at early stage, so the installation script uses them later
if grep -q "QEMU" /proc/bus/input/devices; then PORT=19759 else PORT=19753 fi export PORT dnf install policycoreutils semanage port -a -t ssh_port_t -p tcp ${PORT} sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config IP="$( ip -f inet a show eth0| grep inet| awk '{ print $2}' | cut -d/ -f1 )" IP6="$( ip -6 addr | grep inet6 | awk -F '[ \t]+|/' '{print $3}' | grep -v ^::1 )" IFACE=$( ip addr | grep $IP | awk '{print $NF}' ) OWNER="owner" TIMESTAMP=$(date +%s) SECONDS=0 if [ "$(readlink /etc/localtime)" != "/usr/share/zoneinfo/UTC" ]; then echo "==================================================================================" echo "Setting local time to UTC .." rm -f /etc/localtime ln -s /usr/share/zoneinfo/UTC /etc/localtime fi # Setting the receiver of the root mail sed -ie 's/#root:/root:/' /etc/aliases sed -ie 's/marc/[email protected]/' /etc/aliases echo "#owner: ${OWNER}" >> /etc/aliases newaliases # Disabling IPv6 echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
3) Setting cron job definitions before other scripts start puting their own lines
cd /var/spool/cron/ rm -f root cat > root << 'EOF' # Example of cron job definition on AltaGrade servers: # .---------------- minute (0 - 59) # | .------------- hour (0 - 23) # | | .---------- day of month (1 - 31) # | | | .------- month (1 - 12) OR jan,feb,mar,apr ... # | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat # | | | | | # # 1. Entry: Minute when the process will be started [0-60] # 2. Entry: Hour when the process will be started [0-23] # 3. Entry: Day of the month when the process will be started [1-28/29/30/31] # 4. Entry: Month of the year when the process will be started [1-12] # 5. Entry: Weekday when the process will be started [0-6] [0 is Sunday] # # every x min = */x # So according to this your 5 8 * * 6 would run 8:05 every Saturday. # Ex: 39 * * * * wget -O - -q -t 1 http://YourDrupalSite.com/cron.php?key=YourDrupalSiteCronKeyHere EOF
4) Installing Virtualmin that comes with Apache, PHP, MariaDB
dnf update -y # Perl per https://forum.virtualmin.com/t/virtualmin-install-sh-support-for-centos-8/104880/19 dnf install perl -y # Get and run the Virtualmin installation script wget https://raw.githubusercontent.com/virtualmin/virtualmin-install/master/virtualmin-install.sh sh virtualmin-install.sh -y # Need to run updates once more as fresh Webmin UI shows there is an update for libnghttp2 dnf update -y # We have to stop Webmin in the following particular way, so it successfully restarts # only if we want to start working right away before the reboot, which is less likely. # /etc/webmin/stop # systemctl start webmin.service # /usr/libexec/webmin/changepass.pl /etc/webmin root tik88Fv # If we need $MYSQL_VER variable anywhere in the installation script later # MYSQL_VER=`mysql --version|awk '{ print $5 }'|awk -F\-MariaDB, '{ print $1 }'` # Remove PHP 7.2 that comes by default, because Drupal 9 requires PHP 7.3 and more. # dnf remove php-* # We might leave the original PHP per https://www.virtualmin.com/comment/782623#comment-782623 # just removing php-fpm mode. dnf -y remove php-fpm
5) Installing useful packages
dnf -y install htop git php-devel gcc gcc-c++ pcre-devel patch libxml2-devel pam-devel \ perl-Authen-PAM nmap pecl channel-update pecl.php.net # Per https://github.com/php/pecl-php-uploadprogress PHP-FPM is not supported. # pecl install uploadprogress # echo extension=uploadprogress >> /etc/php.d/30-uploadprogress.ini # pecl install apcu # echo extension=apcu >> /etc/php.d/30-apcu.ini # dnf -y install php-pecl-apcu systemctl enable psacct && systemctl start psacct
6) Configuring Webmin and Virtualmin
727) Installing additional packages
708) Configure AltaOS 8
699) Finalizing the installation script
# Calculating execution time executed="$(($SECONDS / 60)) minutes and $(($SECONDS % 60)) seconds" echo "The installation took $executed" echo "AltaOS8 installed on $(date)" > /root/.altaos/.install_date # Sending the final e-mail notification dnf -y install mailx echo "Installation of AltaOS8 on ${HOSTNAME} completed in $executed. The system is rebooting..." | mail -s "AltaOS8 has been installed on ${HOSTNAME}" 6504506428@vtext.com rm -f /root/recipe* rm -f /usr/src/altaos8.sh updatedb echo "Rebooting the system..." reboot
