找到php配置文件，查看配置文件路径命令：/usr/local/php/bin/php -i |head

1. 配置disable_function

disable_functions = eval,assert,popen,passthru,escapeshellarg,escapeshellcmd,passthru,exec,system,chroot,scandir,chgrp,chown,escapeshellcmd,escapeshellarg,shell_exec,proc_get_status,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,leak,popepassthru,stream_socket_server,popen,proc_open,proc_close

使用命令可以查看禁止的函数：/usr/local/php/bin/php -i |grep disable_f

出现一个警告，这里我们配置一下时区即可：date.timezone='Asia/Chongqing'

2. 配置error_log

打开php.ini，找到如下选项进行配置

display_errors=off

log_errors=on

error_log=/path/to/logfile

error_reporting = E_ALL & ~E_NOTICE

错误级别参考

; E_ALL          所有错误和警告（除E_STRICT外）
; E_ERROR          致命的错误。脚本的执行被暂停。
; E_RECOVERABLE_ERROR 大多数的致命错误。
; E_WARNING       非致命的运行时错误，只是警告，脚本的执行不会停止。
; E_PARSE          编译时解析错误，解析错误应该只由分析器生成。
; E_NOTICE       脚本运行时产生的提醒（往往是我们写的脚本里面的一些bug，比如某个变量没有定义），这个错误不会导致任务中断。
; E_STRICT       脚本运行时产生的提醒信息，会包含一些php抛出的让我们要如何修改的建议信息。
; E_CORE_ERROR    在php启动后发生的致命性错误
; E_CORE_WARNING 在php启动后发生的非致命性错误，也就是警告信息
; E_COMPILE_ERROR php编译时产生的致命性错误
; E_COMPILE_WARNING  php编译时产生的警告信息
; E_USER_ERROR    用户生成的错误
; E_USER_WARNING 用户生成的警告
; E_USER_NOTICE    用户生成的提醒

3. 配置open_basedir

全局配置：php.ini: open_basedir = /dir1/:/dir2

针对虚拟机配置：httpd-vhost.conf: php_admin_value open_basedir "/dir1/:/dir2/"

4. 安装php的扩展模块(memcache)

memcache在php中编译
#  wget http://www.lishiming.net/data/attachment/forum/memcache-2.2.3.tgz
# tar zxvf memcache-2.2.3.tgz
# cd memcache-2.2.3
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install
# cp modules/memcache.so /usr/local/php/ext/ //把memcache.so 拷贝至php的extension_dir下，#查看php extension_dir的方法是  /usr/local/php/bin/php -i |grep extension_dir
修改扩展路径，在php.ini中修改：
extension_dir = "/usr/local/php/ext"
然后在php.ini 中添加
extension = memcache.so

保存后可以利用 /usr/local/php/bin/php -m  检测和查看具体的参数

memcached 的编译安装
wget http://syslab.comsenz.com/downloads/linux/memcached-1.4.5.tar.gz

tar zxvf memcached-1.2.8.tar.gz
cd  memcached-1.2.8
./configure --prefix=/usr/local/memcached
make && make install

启动：

/usr/local/memcached/bin/memcached -m 2048 -p 11211 -l 127.0.0.1 -d -u www
-m  后边指定memecached使用多少内存，单位是M
-p  指定memcached 启动端口
-l  指定绑定的IP
-u  指定以某个账户的身份启动

。。。
