背景：公司一台老机器，上面有个cacti。系统为centos5.X，有天手滑卸载了httpd，但yum源已经不支持centos5系列了，无奈百度上找了一个源内容如下：
<span style="background-color: rgb(255, 102, 102);"><strong><span style="color:#ff6666;"># CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.

装上后发现原本有中文支持的cacti图片全部不显示中文了，百度上找了一圈。全是说要么重新编译rrdtool，要么修改src/cacti/lib/function.php加入setlocale(LC_CTYPE,"zh_CN.UTF-8");之类的全部试遍了还是乱码，最后google到一篇文章，参考其思路解决问题。https://www.iyunv.com/thread-366540-1-1.html
检查httpd/conf/httpd.conf中发现已有AddDefaultCharset GB2312，且cacti的grph栏中可以正常显示中文，编码格式确定。
检查/etc/sysconfig/httpd文件中发现HTTPD_LANG行为注销状态，取消此行前面的#号，修改为HTTPD_LANG=zh_CN.gb2312。
保存，重启httpd，刷新cacti页面，大功告成，流量图中已成功显示中文。
