PHP配置
查看PHP配置文件的位置
# /usr/local/php/bin/php -i |grep -i "loaded configuration file"
把一些存在安全风险的函数禁掉
disable_functions=
phpinfo,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
重启httpd服务使其生效
配置error_log
设置php错误日志
# vi /usr/local/php/etc/php.ini
修改以下内容
log_errors 如果想让PHP记录错误日志,需要设置成on
error_log 设定错误日志路径
error_reporting 设定错误日志的级别,E_ALL为所有类型的日志,&表示并且,~表示排除,意思是在E_ALL的基础上排除掉notice相关的日志
# mkdir /var/log/php 需要保证PHP的错误日志所在目录存在
# chmod 777 /var/log/php
# /usr/local/apache2.4/bin/apachectl graceful
测试
在其中写入错误内容
访问
# curl -A"123" -I -x127.0.0.1:80 www.0209.com/test.php
出现状态码500,说明访问的页面是存在错误的
查看PHP的错误日志判定错误原因
# cat /var/log/php/php_error.log
配置open_basedir
配置文件
# vi /usr/local/php/etc/php.ini
搜索open_basedir
重新加载配置
# /usr/local/apache2.4/bin/apachectl graceful
测试
# cp /usr/local/apache2.4/htdocs/1.php /data/wwwroot/gmd.com/
# curl -x127.0.0.1:80 -I gmd.com/1.php
不能访问
给单个虚拟机设置open_basedir
# vi /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
DocumentRoot "/data/wwwroot/www.0209.com"
ServerName www.0209.com
ServerAlias 0209.com
CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/0209.com-access_%Y%m%d.log 86400"
php_admin_value open_basedir "/data/wwwroot/www.0209.com/:/tmp/"
重新加载配置
# /usr/local/apache2.4/bin/apachectl -t
# /usr/local/apache2.4/bin/apachectl graceful
PHP动态扩展模块安装
查看加载了哪些模块
# /usr/local/php/bin/php -m
安装redis扩展模块
# cd /usr/local/src/
# wget http://pecl.php.net/get/redis-2.2.5.tgz
# tar -zxvf redis-2.2.5.tgz
# cd redis-2.2.5
# yum install -y autoconf
# /usr/local/php/bin/phpize 生成configure文件
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install
# /usr/local/php/bin/php -i |grep extension_dir
# ls /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
# vi /usr/local/php/etc/php.ini
最后加
extension=redis.so
查看是否加载模块
# /usr/local/php/bin/php -m |grep redis
# cd /usr/local/apache2.4/htdocs/
浏览器加载模块
# cd /usr/local/apache2.4/htdocs/
# vi index.php
phpinfo();
?>
重新加载
# /usr/local/apache2.4/bin/apachectl -t
# /usr/local/apache2.4/bin/apachectl graceful
