运维日常：五分钟搞定PHP的redis问题

Posted 2021-01-13

一、前言

1.需求

2.解决
LNMP环境中的php缺少redis扩展包，导致访问页面报错500，处理问题，安装PHP扩展功能redis。

下面记录整个过程，如果不想看，而只想在最短的时间内搞定这个问题，请直接翻到最后，使用脚本。

二、安装

1.下载扩展包

[[email protected] source]# git clone https://github.com/nicolasff/phpredis

2.phpize检测安装

[[email protected] source]# cd phpredis/
[[email protected] phpredis]# /usr/local/php/bin/phpize

----------------------------------------------------------------------
Libraries have been installed in:
   /server/source/phpredis/modules

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‘.
