=== Importing data from MySql sql file ===
{{exclaim}} Notice: existing database will be overwritten

Optional
# (optional) install {{kbd | key =pv}} if the {{kbd | key =pv}} was not installed for RHEL / CentOS / SL / Fedora Linux or {{kbd | key =brew install pv}} for {{Mac}}<ref>[https://formulae.brew.sh/formula/pv pv — Homebrew Formulae]</ref>
# (optional if the 7Zip was not installed) {{kbd | key =yum install p7zip}} for RHEL / CentOS / SL / Fedora Linux
'''method 1''': Import *.sql file: 
# (optional if the .sql file was compressed) {{kbd | key =unzip data.zip}} or {{kbd | key =gzip -d data.gz}} if the file was compressed by gzip
# {{kbd | key =  <nowiki>mysql -u username -p -h localhost --default_character_set utf8 --force DATA_BASE_NAME < data.sql</nowiki>}} <ref>[http://www.cyberciti.biz/faq/import-mysql-dumpfile-sql-datafile-into-my-database/ Import MySQL Dumpfile, SQL Datafile Into My Database]</ref> and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }}

'''method 2''': Import *.sql file with {{kbd | key =--binary-mode}} (useful when the dump contains complex JSON string, binary data or BLOB fields, to avoid "\r\n" being misinterpreted and causing corrupted imports):
# (optional if the .sql file was compressed) {{kbd | key =unzip data.zip}} or {{kbd | key =gzip -d data.gz}} if the file was compressed by gzip
# {{kbd | key =  <nowiki>mysql -u username -p -h localhost --default_character_set utf8 --binary-mode --force DATA_BASE_NAME < data.sql</nowiki>}} <ref>[https://dev.mysql.com/doc/refman/8.0/en/mysql-command-options.html#option_mysql_binary-mode mysql Command-Line Client Options — MySQL Reference Manual]</ref> and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }} {{kbd | key =--binary-mode}} disables all client-side conversions of {{kbd | key =\r\n}} and treats {{kbd | key =\0}} as a normal character, which is recommended whenever the dump was produced with {{kbd | key =mysqldump --hex-blob}} or otherwise contains binary/BLOB content

'''method 3''': Import the *.sql file (especially for BIG sql file). It will show a progress bar and estimated time to complete the mysql command<ref>[http://dba.stackexchange.com/questions/17367/how-can-i-monitor-the-progress-of-an-import-of-a-large-sql-file mysql - How can I monitor the progress of an import of a large .sql file? - Database Administrators Stack Exchange]</ref>: 
# Install {{kbd | key =pv}}
# {{kbd | key =  <nowiki>pv data.sql | mysql -u username -p -h localhost --default_character_set utf8 --force DATA_BASE_NAME</nowiki>}} <ref>[http://www.cyberciti.biz/faq/import-mysql-dumpfile-sql-datafile-into-my-database/ Import MySQL Dumpfile, SQL Datafile Into My Database]</ref> and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }} The console window will show ETA (Estimated Time of Arrival)

'''method 4''': Same as method 3, but combined with {{kbd | key =--binary-mode}} to safely handle binary/BLOB content while showing a progress bar:
# Install {{kbd | key =pv}}
# {{kbd | key =  <nowiki>pv data.sql | mysql -u username -p -h localhost --default_character_set utf8 --binary-mode --force DATA_BASE_NAME</nowiki>}} and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }} The console window will show ETA (Estimated Time of Arrival), and {{kbd | key =--binary-mode}} disables all client-side conversions of {{kbd | key =\r\n}} and treats {{kbd | key =\0}} as a normal character, which is recommended whenever the dump was produced with {{kbd | key =mysqldump --hex-blob}} or otherwise contains binary/BLOB content

'''method 5''': {{Gd}} Import the compressed *.sql file with gzip (especially for BIG sql file). It will show a progress bar and estimated time to complete the mysql command: 
# Install {{kbd | key =pv}}
# Check if the file is gzip format (test the compressed file integrity) ex: (1) {{kbd | key =  <nowiki>gunzip -t database.sql.gz</nowiki>}} If not, it will return the message "gzip: database.sql.gz: not in gzip format." (2) Using [http://www.winmd5.com/ WinMD5 Free] for {{Win}} or [http://linux.die.net/man/1/md5sum md5sum] command for {{Linux}} to obtain MD5 checksum of files.
# {{kbd | key =  <nowiki> pv database.sql.gz | gunzip | mysql -u username -p -h localhost --default_character_set utf8 --force DATA_BASE_NAME</nowiki>}} <ref>[http://journal.andrewloe.com/2009/05/12/pv-gzip-mysql/ pv + gzip + mysql — W. Andrew Loe III: Journal]</ref> and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }} The console window will show ETA (Estimated Time of Arrival)

'''method 6''': Same as method 5, but combined with {{kbd | key =--binary-mode}} to safely handle binary/BLOB content while showing a progress bar:
# Install {{kbd | key =pv}}
# Check if the file is gzip format (test the compressed file integrity) ex: (1) {{kbd | key =  <nowiki>gunzip -t database.sql.gz</nowiki>}} If not, it will return the message "gzip: database.sql.gz: not in gzip format." (2) Using [http://www.winmd5.com/ WinMD5 Free] for {{Win}} or [http://linux.die.net/man/1/md5sum md5sum] command for {{Linux}} to obtain MD5 checksum of files.
# {{kbd | key =  <nowiki> pv database.sql.gz | gunzip -c | mysql -u username -p -h localhost --default_character_set utf8 --binary-mode --force DATA_BASE_NAME</nowiki>}} and press {{kbd | key =  <nowiki>Enter</nowiki> }}
# enter {{kbd | key =  <nowiki>password</nowiki> }} and press {{kbd | key =  <nowiki>Enter</nowiki> }} The console window will show ETA (Estimated Time of Arrival), and {{kbd | key =--binary-mode}} disables all client-side conversions of {{kbd | key =\r\n}} and treats {{kbd | key =\0}} as a normal character, which is recommended whenever the dump was produced with {{kbd | key =mysqldump --hex-blob}} or otherwise contains binary/BLOB content

'''method 7''': Import ZIP file to MySql directly:
# Install the 7Zip
# {{kbd | key = <nowiki>7za x -so data.zip | mysql -u username -p -h localhost --default_character_set utf8 --force DATA_BASE_NAME</nowiki>}} <ref>[http://stackoverflow.com/questions/11267309/importing-zipped-files-in-mysql-using-command-line database - Importing zipped files in Mysql using command line - Stack Overflow]</ref><ref>[http://needs-be.blogspot.tw/2011/01/install-7zip-on-centos-55.html Install 7Zip on CentOS 5.5]</ref> and press {{kbd | key =  <nowiki>Enter</nowiki> }}
