Hapus File Lama di linux

lumbans — Wed, 11 Nov 2009 06:02:47 +0000

Cara menghapus file lama dari n hari, maksudnya n adalah jumlah hari.
Contoh kasus saya backup MySQL setiap hari di folder /home/cyberthug/backup/, agar space hardisk tidak cepat habis maka perlu dibuat atau di tambah kan script untuk menghapus file lama.
Berikut adalah caranya;
#find /home/cyberthug/backup/* -mtime +7 -exec rm {} \;

Keterangan :
1. find : untuk mencari file pada folder /home/cyberthug/backup/
2. -mtime : option modified time atau tanggal modifikasi file
3. +7 : ini adalah jumlah hari dimana file yg lebih dari 7 hari
4. -exec : untuk melaksanakan perintah/command
5. rm : hapus file
6. {} \; : untuk mengakhiri perintah/command tersebut.

Semoga bermanfaat.

MySQL Instance Manager on phpMyAdmin

lumbans — Thu, 08 Oct 2009 07:23:37 +0000

Last few days ago my friend ask me to install phpMyAdmin on CentOS 5.0 which in has installed MySQL Server. In our server the database/MySQL has many instance so mysql runs as MySQL Instance Manager.
Cause this is my first chase to install phpMyAdmin with MySQL Instance Manager, so i looking for how to install it.

On this server, Apache, php and MySQL Library must installed before if didn’t install using yum :
yum install httpd mysql-share-community php-cli php-mbstring php-pdo phpMyAdmin php-common php php-devel php-mysql

After all those files install, then will get phpMyAdmin.conf on /etc/httpd/conf.d/ ;
# phpMyAdmin - Web based MySQL browser written in php # # Allows only localhost by default # # But allowing phpMyAdmin to anyone other than localhost should be considered # dangerous unless properly secured by SSL Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin order deny,allow deny from all allow from 10.62.31.0/24 # This directory does not require access over HTTP - taken from the original # phpMyAdmin upstream tarball # Order Deny,Allow Deny from All Allow from None # This configuration prevents mod_security at phpMyAdmin directories from # filtering SQL etc. This may break your mod_security implementation. # # # # SecRuleInheritance Off # #

Now we will configure to integrated MySQL Instance Manager with phpMyAdmin, first open /etc/my.cnf to see mysql configuration.
this is the example of mysql configuration :
[mysql.server] use-manager [manager] default-mysqld-path = /usr/sbin/mysqld socket = /db/log/manager.sock pid-file = /db/log/manager.pid password-file = /db/mysqlmanager.passwd port = 1999 bind-address = 127.0.0.1 user = mysql [mysqld] port = 3306 user =mysql server-id = 1 datadir = /db/testdb socket = /db/testdb/mysql.sock log-error = /db/log/mysql/testdb.log pid-file = /db/log/mysql/testdb.pid log-bin=/db/log/mysql/testdb-bin sql-mode=STRICT_ALL_TABLES,ANSI_QUOTES,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE skip-locking key_buffer = 384M max_allowed_packet = 1M max_connections = 500 table_cache = 512 sort_buffer_size = 2M read_buffer_size = 2M myisam_sort_buffer_size = 64M thread_cache = 8 query_cache_size = 64M query_cache_limit = 2M thread_concurrency = 8 skip-bdb table_cache = 8000 key_buffer_size = 6GB read_buffer_size = 2M max_heap_table_size = 1G sort_buffer_size = 8K join_buffer_size = 8K thread_cache_size = 256 thread_stack = 256K read_rnd_buffer_size = 16M thread_concurrency = 8 query_cache_size = 64M query_cache_limit = 2M long_query_time = 0 tmp_table_size = 512M default-storage-engine = INNODB ....

We just need part of [manager] which is path of socket socket = /db/testdb/mysql.sock.
Then phpMyadmin to integrate with mysql, open file config.inch.php usually on /etc/phpMyAdmin/ or /usr/share/phpMyAdmin folder.

Open your favorite editor (I usually using Vi) then find this part and set like this ;
Before :
$cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['port'] = ''; $cfg['Servers'][$i]['socket'] = ''; $cfg['Servers'][$i]['connect_type'] = 'tcp';
After :
$cfg['Servers'][$i]['host'] = '192.168.0.99'; -->Your IP MySQL Server $cfg['Servers'][$i]['port'] = ''; $cfg['Servers'][$i]['socket'] = '/db/log/manager.sock'; $cfg['Servers'][$i]['connect_type'] = 'socket';

then save and exit “:wq”.
Now restart your apache, then open your browser and input address http://192.168.0.99/phpMyAdmin, if show popup to input username and password of your MySQL Instance Manager. Your succeed….

Done
