前几天在robinz那看到了在Dreamhost上安装eAccelerator的教程，听说eAccelerator要比zend快多了，手就有点痒，这几天都在尝试编译安装PHP-4.4.4，但已经出错了三次，大都是因为脚本的问题，准备第四次的时候竟然一不小心rm -rf php *差点把所有东西都删了，幸好还有较早前的备份才恢复过来，今天就把WordPress升到2.0.6，趁还有时间顺便也把页面的css调整了一下，加了两张背景。

实际动手才发觉跟想象的也差太远了，安装PHP4就是因为参数和网数的问题令成功几率大大降低，而且在网上的那些脚本多数都不太完全对的，需要改动的地方也不少。就PHP4的编译小弟也积累了些经验， 刚开始我只按照robinz的方法装的，但是因为php4已经出到4.4.4了，而iMap也升级到2006了，2004g的下载地址也已经失效了，还有一好几个文件镜像都失效，后来只好参照Dreamhost官方提供的脚本重新编译，而又因为Dreamhost的脚本写的比较优美，所以我最后还是以它为基础按照robinz的参数重新安装。在这里有几点要注意的，Dreamhost提供的脚本是默认没有打开FastCGI参数的，而robinz上面又有几个变量稍微不同，还有编译的时候最好把脚本放到$HOME目录执行，这样才不会产生多余的php链接。

下面是我修改过的脚本

Download: instphp4.sh

运行

chmod +x instphp4.sh
./instphp4.sh

wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.59.tar.bz2
tar -xjf autoconf-2.59.tar.bz2
cd autoconf-2.59
./configure -prefix=YOUR PATH
make
make install

安装automake

wget http://ftp.gnu.org/gnu/automake/automake-1.9.6.tar.bz2
tar -xjf automake-1.9.6.tar.bz2
cd automake-1.9.6
./configure -prefix=YOUR PATH
make
make install

然后我们来看看eAccelerator的软件环境需求：
apache 1.3, apache 2.0 (prefork), mod_php4/5
我们的Dreamhost都能够支持，好了，下面到请主角出场：

安装eAccelerator（下面的地址如果不通的话最好自己到eAccelerator的PojectPage找合适的镜像）

wget http://voxel.dl.sourceforge.net/sourceforge/eaccelerator/eaccelerator-0.9.5.tar.bz2
tar -xjf eaccelerator-0.9.5.tar.bz2
cd eaccelerator-0.9.5
export PATH=$PATH:YOUR PATH/bin #这里的是指你安装autoconf的目录，譬如我的是$HOME/local/bin
export PHP_PREFIX=YOUR PHP PATH #这里是你的安装php的位置，就是$HOME/php，但有一个小细节要注意的，在robinz的文里是写export PHP_PREFIX= YOUR PHP PATH/bin的，其实如果这样写的话，configure是不会成功的
$PHP_PREFIX/bin/phpize
./configure -prefix=YOUR PATH --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
make
make install #最好还是make install一下，不make install会有la文件
mv YOUR PHP PATH/lib/php/extensions/no-debug-non-zts-一行数字/eaccelerator.so YOUR PHP PATH/lib/php/extensions/
rm -r YOUR PHP PATH/lib/php/extensions/no-debug-non-zts-一行数字/

[eAccelerator]
zend_extension="/home/YOUR PHP PATH/lib/php/extensions/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/home/YOUR HOME/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

[Zend]
zend_extension="/usr/local/dh/apache/template/phpext/ZendExtensionManager.so"
zend_extension="/usr/local/dh/apache/template/phpext/zend_optimizer4/ZendOptimizer.so"
zend_optimizer.optimization_level=1023

然后再运行

mkdir -p ~/tmp/eaccelerator
chmod 777 ~/tmp/eaccelerator

最后，别忘了在你的.htaccess文件里加上

AddHandler phpFour .php
Action phpFour /cgi-bin/php.cgi

再下一个iProber 探针，看看PHPINFO就可以看到

先是数据库备份脚本
#ftp Info
host=HOST #ftp host
UserName=USER #ftp user name
Passwd=PASSWD #fto user password

#MySQL Info
SQL_host=DB_HOST #MySQL host
SQL_User=DB_USER #MySQL UserName
SQL_Passwd=DB_PASSWD #User Password
SQL_db=DB_NAME #database name

backup_path=/home/YOUR TMP PATH #set saved backup path
file=$SQL_db-$(date +%Y%m%d).tar.gz
MySQL_path=/usr/bin #set the mysql database bin path

cd $backup_path
#export database
$MySQL_path/mysqldump -h $SQL_host -u$SQL_User -p$SQL_Passwd --databases $SQL_db>$SQL_db.dump

sleep 5s
#file tar
tar -czf $backup_path/$file $SQL_db.dump
gpg -e -r GPGID $file #有关gpg加解密请GOOGLE一下

cd $backup_path

#file ftp
ftp -i -n <<!
open $host
user $UserName $Passwd
cd /dbbak #请事先在你的备份用FTP上建立此目录
put $file.gpg
bye
!

sleep 10s
rm -rf $backup_path/$file
rm -rf $backup_path/$SQL_db.dump
rm -rf $backup_path/$file.gpg

---

然后是文件备份的
WEBFILE=webdir-$(date +%Y%m%d).tar.gz
cd $HOME

sleep 1s
tar -czf $HOME/YOUR TMP PATH/webdir-$(date +%Y%m%d).tar.gz $HOME/YOUR PATH

sleep 10s
cd $HOME/YOUR TMP PATH
gpg -e -r YOUR GPG ID $WEBFILE

sleep 15s
ftp -i -n <<!
open YOUR FTP HOST
user USERNAME PASSWD
cd webbak #这个也是要事先建好
put $WEBFILE.gpg
bye
!

sleep 5s
rm -rf $HOME/YOUR TMP PATH/$WEBFILE.gpg
rm -rf $HOME/YOUR TMP PATH/$WEBFILE

---

Enjoy!
