Record php5.4 and php-redis conflict resolution

Recently, the ubuntu source is updated, causing some lib conflicts between the original new source and the local system Library. as a result, the system desktop displays an exception. later, only the new version is installed, phpbench is installed, and redis is also installed, php-redis extension, php-redis extension 2, 10. However, when I put the original project on, I reported that n recently updated the ubuntu source, resulting in some lib conflicts between the original new source and the local system Library, leading to abnormal display on the system desktop. later, I only re-installed it, php5.4.9 is installed, redis, php-redis extension, and php-redis extension 2 and 10 are also installed. However, once the original project is put up, the nginx 502 error will be reported (nginx 502 error is a headache ). Open nginx log to view [error] 29229 #0: * 1403 recv () failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: do not know the cloud. Then open the php-fpm error log and obtain the log [21:22:23] WARNING: [pool www] child 12026 exited on signal 11 (SIGSEGV-core dumped) after 5.997917 seconds from start [08-Oct-2013 21:22:23] NOTICE: [pool www] child 12034 started can be determined that php-fpm restarts a process after a time point. There is no clue. I searched the internet a lot and found a useful tracking method. 1. set php-fpm to start only one work process. 2. restart php-fpm, run ps aux | grep php-fpm to get the work process id pid 3. under strace-p pid, the following information is obtained: getcwd ("/home/www/wms2.xxxx.com", 4096) = 26 lstat ("/home/www/Taobao", 0x7ffff4e30a10) =-1 ENOENT (No such file or directory) lstat ("/home/www/Taobao", 0x7ffff4e30a10) =-1 ENOENT (No such file or directory) lstat ("/home/www/wms2.

You can basically find that a problem occurs in php-redis. After tracing, a code error occurs: public function conn () {try {$ this-> _ redis-> pconnect ($ this-> host, $ this-> port, $ this-> timeout); // Set client option. must AFTER connected // var_dump (Redis: OPT_SERIALIZER, Redis: SERIALIZER_PHP); exit (); $ this-> _ redis-> setOption (Redis: OPT_SERIALIZER, Redis :: SERIALIZER_PHP); // $ this-> _ redis-> setOption (0, 0); $ this-> _ redis-> auth ("xm_wms_rs "); $ this-> connected = true;} catch (RedisE Xception $ e) {throw new CHttpException (500, "Redis occurs an error :". $ e-> getMessage ();} when the code in red is used, the error 502 will be reported, and the Green code is correct. SetOption: Is this a magic horse? Check php-redis api $ redis-> setOption (Redis: OPT_SERIALIZER, Redis: SERIALIZER_NONE ); // don't serialize data does not serialize data $ redis-> setOption (Redis: OPT_SERIALIZER, Redis: SERIALIZER_PHP ); // use built-in serialize/unserialize with php built-in serialization $ redis-> setOption (Redis: OPT_SERIALIZER, Redis: SERIALIZER_IGBINARY ); // use igBinary serialize/unserialize to serialize $ redis-> setOption (Redis: OPT_PREFIX, 'myappname: ') with extended IGBINARY :'); // Use custom prefix on all keys redis key prefix $ redis-> setOption (Redis: OPT_SERIALIZER, Redis: SERIALIZER_PHP ); if this is used, why does the built-in serialization of php cause an error? What happened? Later, the IGBINARY extension was installed. Finally, install php-redis with the latest version 2.24 and run it again.
