1. # /usr/local/php/bin/php -i |grep -i "loaded configuration file" 
  2. // 查看PHP配置文件所在位置的命令 
  3. // 如果出现PHP warning:的警告信息，就是需要php.ini，找到data.timezone设置
  4. // 将data.timezone =  配置成 data.timezone = Asia/shanghai
  5. # /usr/local/php/bin/php -i |grep -i "loaded configuration file" 
  6. Loaded Configuration File => /usr/local/php/etc/php.ini // 加载配置布

1、PHP的disable_functions

  3. # /usr/local/apache2.4/bin/apachectl graceful //重新加载配置服务

2、配置error_log


image.png

  1. # vim /usr/local/php/etc/php.ini

  7. error_reporing = E_ALL & ~E_NOTICE
  8. // 搜索display_errors修改
  9. display_errors = Off 
  10. # mkdir /var/log/php //
  11. # chmod 777 /var/log/php //需要保证PHP的错误日志所在目录存在，并且权限为可写
  12. # /usr/local/apache2.4/bin/apachectl graceful // 重新加载配置服务
  13. // 测试
  14. # vim /data/wwwroot/ww.123.com/test.php //写入内容，故意把结尾去掉
  15. <?php
  16. echo 111

3、配置 open_basedir

  1. # vim /usr/local/php/etc/php.ini //搜索open_basedir 修改
  2. open_basedir = /tmp:/data/wwwroot/www.123.com
  3. # /usr/local/apache2.4/bin/apachectl graceful //重新加载配置服务
