python 定时备份MySQL数据库

作者:蘑菇 日期:2010-04-19 16:50

虽然作为程序员知道备份的重要性，但是一直没有落实过。由于近来网站的不稳定，才开始意识到：备份！太重要了！
于是写了个定时备份数据库的脚本，并发送邮件保存备份文件。

我们用到一个数据库配置文件： db.conf。 格式如下：

dbuser dbpass dbname
每行一条记录写下来，是我们要备份的数据库的列表。

下面我们要写到的是备份脚本：

下载: db_backup.py
#!/usr/bin/python
#Author: Liubing
#Email : liubing@eduicc.com
#date  : Mon, Apr 19th
 
import os
import time
import smtplib
import email.MIMEMultipart
import email.MIMEText
import email.MIMEBase
 
#directory name
today = time.strftime("%Y-%m-%d")
#backup file name
tgzfile = today+".tar.gz"
 
#mkdir
if os.path.isdir(today):
    os.system("rm -rf "+today)   
os.mkdir(today)
 
#backup databases
fp = file("db.conf");
while True:
    line = fp.readline();
    if len(line) == 0:
        break;
    db_conf = line.rstrip('\n').split(' ');
    bak_shell = "mysqldump -u"+db_conf[0]+" -p"+db_conf[1]+" "+db_conf[2]+" > "+today+"/"+db_conf[2]+"_"+today+".sql"
    print bak_shell
    os.system(bak_shell)
fp.close();
 
#create .tar.gz file
os.system("tar -zcvf "+tgzfile+" "+today)
os.system("rm -rf "+today)
 
#Send Email
From = "liubing@eduicc.com"
To = "liubing@eduicc.com"
 
server = smtplib.SMTP("localhost");
 
main_msg = email.MIMEMultipart.MIMEMultipart()
text_msg = email.MIMEText.MIMEText("Backup databases")
main_msg.attach(text_msg)
 
contype = 'application/octet-stream'
maintype, subtype = contype.split('/', 1)
 
#read tgzfile
data = open(tgzfile, 'rb')
file_msg = email.MIMEBase.MIMEBase(maintype, subtype)
file_msg.set_payload(data.read())
data.close()
email.Encoders.encode_base64(file_msg)
 
#set email header
basename = os.path.basename(tgzfile)
file_msg.add_header('Content-Disposition', 'attachment', filename=basename)
main_msg.attach(file_msg)
 
main_msg['From'] = From
main_msg['To'] = To
main_msg['Subject'] = 'daily backup'
main_msg['Date'] = email.Utils.formatdate()
 
fullText = main_msg.as_string()
 
try:
    server.sendmail(From, To, fullText)
finally:
    server.quit()
os.system("rm -f "+tgzfile)


然后，我们改变db_backup.py的属性：

chmod 0755 db_backup.py
最后，我们把脚本加到crontab中

#backup at 3:00 every day
0 3 * * * /usr/bin/python /root/db_backup.py > /dev/null

Joomla 调用module的方法

作者:蘑菇 日期:2010-04-18 22:46

Joomla调用module一般有以下几个方法：

1. 写在模板首页

<jdoc:include type="modules" name="position" />

    这种方法会受到Itemid的限制

2. 写在文章里

{loadmodule positiion}

  这种方法不会受到Itemid的限制，是内嵌在文章里的。就是说只要显示文章，就会显示引入的module

3. 用JModuleHelper类引入

<?php
$modules = JModuleHelper::getModules("position"); //这里会取到放在同一个位置的所有module，得到的是一个数组
echo JModuleHelper::renderModule($modules[index]); //这里的index是放在同一位置的module的索引

CentOS + Nginx + PHP + MySQL 环境搭建

作者:蘑菇 日期:2010-04-18 22:09

一、软件环境
CentOS 5.4 :
Nginx 0.8 : http://nginx.org/download/nginx-0.8.35.tar.gz
PHP 5.2.10 : http://www.eduicc.com/soft/php-5.2.10.tar.gz
MySQL 5.4.15 : http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.45.tar.gz/from/http://mysql.ntu.edu.tw/

二、安装
  1. 准备工作
    这一步我称它为“准备工作”，其实是安装一些系统编译及其他环境
yum -y install patch make gcc gcc-c++ gcc-g77 flex bison libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel

#安装编码格式转换库
wget http://www.eduicc.com/soft/libiconv-1.13.tar.gz
tar -zxvf libiconv-1.13.tar.gz
cd libiconv-1.13
./configure --prefix=/usr/local
make && make install
cd ..

#安装libmcrypt库

cd libmcrypt-2.5.8
./configure
make && make install
ldconfig
cd libltdl
./configure --enable-libltdl-install
make && make install
cd ../../

#安装php-mhash扩展库
wget http://www.eduicc.com/soft/mhash-0.9.9.9.tar.gz
tar -zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9
./configure
make && make install
cd ..
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

    wget http://www.eduicc.com/soft/mcrypt-2.6.8.tar.gz
tar -zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8
./configure
make && make install
cd ..

  2. 安装MySQL

tar -zxvf mysql-5.1.54.tar.gz
cd mysql-5.1.54
./configure --prefix=/usr/local/mysql --enable-assembler --with-charset=utf8 --enable-thread-safe-client --with-extra-charsets=all --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile
make && make install
cd ..
    
#添加mysql用户和用户组
groupadd mysql
useradd -g mysql mysql
cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysql_install_db --user=mysql
chown -R mysql /usr/local/mysql/var
chgrp -R mysql /usr/local/mysql/.

#设置mysql开机自启动
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql
chmod 755 /etc/init.d/mysql
chkconfig --level 345 mysql on

#增加mysql动态链接库文件
echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
echo "/usr/local/lib" >>/etc/ld.so.conf
ldconfig

ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql

#添加root密码
/etc/init.d/mysql start
/usr/local/mysql/bin/mysqladmin -u root password root
/etc/init.d/mysql restart
/etc/init.d/mysql stop

#去掉mysql集群服务
chkconfig mysql-ndb off
chkconfig mysql-ndb-mgm off 
  3. 安装PHP
#我们用php-fpm来管理fastcgi
wget http://www.eduicc.com/soft/php-5.2.10-fpm-0.5.11.diff.gz
tar -zxvf php-5.2.10.tar.gz
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1

! 这里我们要先将autoconf降低版本，否则可能会出现： buildconf: Your version of autoconf likely contains buggy cache code.
yum -y install autoconf213
    export PHP_AUTOCONF=/usr/bin/autoconf2.13

cd php-5.2.10
./buildconf --force
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-ftp --without-pear
make ZEND_EXTRA_LIBS='-libiconv'
make install
cp php.ini-dist /usr/local/php/etc/

  4. 安装nginx
#安装pcre (Perl Compatible Regular Expressions正则表达式库)
wget http://www.eduicc.com/soft/pcre-7.9.tar.gz
tar -zxvf pcre-7.9.tar.gz
cd pcre-7.9
./configure
make && make install
cd ..

tar -zxvf nginx-0.8.35.tar.gz
cd nginx-0.8.35
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install

#有关nginx.conf和php-fpm.conf的配置可以参照：nginx.conf 和 php-fpm.conf
 
5. 测试
我们先来写一个脚本
vi /etc/init.d/run

写入以下内容
   ulimit -SHn 51200
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
   
   启动测试：
chown 0755 /etc/init.d/run
/etc/init.d/run
/etc/init.d/mysql start
  好了，在/var/www/localhost下写个phpinfo测试下吧！

  感谢老婆的大力支持!

Joomla 1.6的权限控制分析图例

作者:蘑菇 日期:2010-02-09 11:42

上次发了一篇权限分析，可能对lft和rgt写的不是太清楚，于是做了个图例，应该比较好理解一些。
