測試機上測試一些數據需要用到redis擴展，偷懶yum安裝的php，以前yum install php-pecl-redis.x86_64可以安裝擴展，這次找不到安裝包，不折騰手動安裝下。
1.下載phpredis
cd /usr/local/src
wget https://github.com/nicolasff/phpredis/archive/2.2.4.tar.gz
tar -zxvf 2.2.4.tar.gz
cd phpredis-2.2.4/
2.用phpize生成configure配置文件
/usr/bin/phpize #會生成幾個新文件，默認安裝路徑自定義的按照自定義路徑；
./configure --with-php-config=/usr/bin/php-config
make #編譯
make install #安裝
make test #測試
3.配置php支持
vim /usr/local/php/etc/php.ini #編輯配置文件，在最後一行添加以下內容
extension="redis.so"
4.
重啓http加載查看phpinfo信息：
redis
Redis Supportenabled
Redis Version2.2.4
成功！
php擴展Protobuf
下載protobuf擴展包：wget https://github.com/allegro/php-protobuf/archive/master.zip這個master.zip會報錯；
master.zip
cd /home/tools/php-protobuf-master/
phpize
可能會報錯php-devel
yum install php-devel
./configure
make && make install
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.
Installing shared extensions: /usr/lib64/php/modules/
然後再php.ini增加
extension = protocolbuffers.so
重啓下http就可以了；
裝載protobuff庫：
pear channel-discover 
pear.pollinimini.net
pear install drslump/Protobuf-beta
mcryp擴展：
yum install libmcrypt libmcrypt-devel mcrypt mhash 如果報錯找不到補丁的話手動安裝；
下載Libmcrypt,mhash,mcrypt安裝包
Libmcrypt(libmcrypt-2.5.8.tar.gz)：http://sourceforge.net/project/showfiles.php?group_id=87941&package_id=91774&release_id=487459
mcrypt(mcrypt-2.6.8.tar.gz ):http://sourceforge.net/project/showfiles.php?group_id=87941&package_id=91948&release_id=642101
mhash(mhash-0.9.9.9.tar.gz):http://sourceforge.net/project/showfiles.php?group_id=4286&package_id=4300&release_id=645636
2.先安裝Libmcrypt
tar -zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure
make
make install
說明：libmcript默認安裝在/usr/local
3.再安裝mhash
tar -zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9
./configure
make && make install
4.最後安裝mcrypt
tar -zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8
LD_LIBRARY_PATH=/usr/local/lib ./configure
make && make install
說明：由於在配置Mcrypt時，會找不到libmcrypt的鏈接庫，導致無法編譯，因爲Libmcrypt的鏈接庫在/usr/local/lib文件夾下。
因次，在配置mcrypt時要加入LD_LIBRARY_PATH=/usr/local/lib導入鍵接庫。
到http://cn.php.net/releases/ 網頁下找到自己對應php版本，下載後解壓
cd php-5.4.16/ext/mcrypt/
phpize (執行phpize命令（phpize是用來擴展php擴展模塊的，通過phpize可以建立php的外掛模塊，如果沒有？yum install php-devel)
phpize
Configuring for:
PHP Api Version: 20100412
Zend Module Api No: 20100525
Zend Extension Api No: 220100525
yum 安裝php./configure就可以，定製的需要自己的路徑如比：./configure --with-php-config=/usr/bin/php-config
./configure
make && make install
Libraries have been installed in:
/home/tools/php-5.4.16/ext/mcrypt/modules
