1. System Backup
1.1 Backup under /var/www/html
① Create backup_all.sh script under /opt/script
# vi /opt/script/backup_all.sh
backup_all.sh script contents
10-day data storage
#!/bin/bash
#date processing
TODAY=`/bin/date +%Y%m%d`
DAY_AGO=`/bin/date --date '10day ago' +%Y%m%d`
#backup source
HTML_DIR="/var/www/html"
#output file
BACKUP_DIR="/var/www/backup/www_bak" #Backup File Output Destination
RUN_FLAG="/var/www/backup/www_bak/www_flag"
/bin/mkdir -p ${BACKUP_DIR}
/bin/touch ${RUN_FLAG}
/bin/tar vfcz ${BACKUP_DIR}/www_back_${TODAY}.tar.gz ${HTML_DIR}
/bin/chmod 644 ${BACKUP_DIR}/www_back_${TODAY}.tar.gz
if [ -f ${BACKUP_DIR}/www_back_${DAY_AGO}.tar.gz ];
then
/bin/rm -f ${BACKUP_DIR}/www_back_${DAY_AGO}.tar.gz
fi
/bin/rm -f ${RUN_FLAG}
➁Grant execute permissions to scripts
# chmod 755 /opt/script/backup_all.sh
➂Create a directory to store backup files
# mkdir -p /var/www/backup/www_bak
# chmod 755 /var/www/backup/www_bak
④Add settings to cron for periodic backups
# crontab -e
0 6 * * * /opt/script/backup_all.sh > /dev/null 2>&1
1.2 MariaDB database backup
①Create db_backup.sh script under /opt/script
# vi /opt/script/db_backup.sh
db_backup.sh script contents
#!/bin/bash
export LANG=ja_JP.eucJP
export PATH="$PATH":/usr/bin
export MYSQL_HOME=/etc/mysql
export MYLIB=/usr/lib/mysql
export MANPATH=":wq/usr/share/man"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}":"MYLIB"
#MariaDB Connection Settings
MYUSER="root" #MariaDBb connection user name
MYPASS="********" #MariaDB connection password
#Date processing related
TIME_STRING=`/bin/date '+%Y%m%d'`
DAY_AGO=`/bin/date --date '10day ago' +%Y%m%d`
#Output File Related
DB_BAK_DIR="/var/www/backup/db_bak" #Backup File Output Destination
RUN_FLAG="${DB_BAK_DIR}/db_my_flag"
MYSQL_BACKUP_FILE=${DB_BAK_DIR}/mariadb_backup_"${TIME_STRING}".dump
/bin/mkdir -p ${DB_BAK_DIR}
/bin/touch ${RUN_FLAG}
mysqldump -u${MYUSER} -p${MYPASS} --all-databases --events > ${MYSQL_BACKUP_FILE}
/bin/gzip ${MYSQL_BACKUP_FILE}
if [ -f ${DB_BAK_DIR}/${MT_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${MT_DB}"${DAY_AGO}".dump.gz
fi
if [ -f ${DB_BAK_DIR}/${XOOPS_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${XOOPS_DB}"${DAY_AGO}".dump.gz
fi
if [ -f ${DB_BAK_DIR}/${GEEKLOG_DB}"${DAY_AGO}".dump.gz ];
then
/bin/rm -f ${DB_BAK_DIR}/${GEEKLOG_DB}"${DAY_AGO}".dump.gz
fi
/bin/rm -f ${RUN_FLAG}
➁Grant execute permissions to scripts
# chmod 755 /opt/script/db_backup.sh
➂Create a directory to store backup files
# mkdir -p /var/www/backup/db_bak
# chmod 755 /var/www/backup/db_bak
③Add settings to cron for periodic backups
# crontab -e
0 7 * * * /opt/script/db_backup.sh > /dev/null 2>&1
2. System Restore
2.1 Restore backup files under HTML
① Store HTML backup files used for backup in the "/ (root)" directory
Select the backup file with the latest timestamp
# cd /var/www/backup/www_bak
# cp www_back_[time stamp].tar.gz /
# cd /
# tar zxvf www_back_[time stamp].tar.gz
2.2 Restore MariaDB database
①Save DB backup file to any directory and extract data
# cd /var/www/backup/db_bak
# gzip -d mariadb_backup_[time stamp].dump.gz
②Restore MariaDB
# mysql -u root -p < mariadb_backup_[time stamp].dump
