PHP编程：纪录php5.4与php-redis抵触的办理

我的这套线路可能跟许多学习PHP的爱好者不谋而合，这也算是一个循序渐进的学习过程，不过新手不要看到上面的概括就以为学习蛮简单的，默默在此不得不对您稍微泼一下冷水，任何工具其实都不简单。比来因为update了ubuntu的源，招致本来新源与当地体系库一些lib抵触，招致体系桌面显现非常，厥后只要重装，新安装了php5.4.9,还安装了redis，php-redis扩大，php-redis扩大2,10。但把本来的项目一放上往，就报nginx502毛病（nginx502毛病真是个很头疼的成绩）。翻开nginx日记检察[error]29229#0:*1403recv()failed(104:Connectionresetbypeer)whilereadingresponseheaderfromupstream,client:127.0.0.1,server:不晓得所云。厥后翻开php-fpm毛病日记，失掉的log日记[08-Oct-201321:22:23]WARNING:[poolwww]child12026exitedonsignal11(SIGSEGV-coredumped)after5.997917secondsfromstart[08-Oct-201321:22:23]NOTICE:[poolwww]child12034started能够断定的一点，是php-fpm在一个工夫点后重启了一个历程。仍是毫无眉目。在网上搜了一年夜遍，有个有效的跟踪办法。1、设置php-fpm，只起一个work历程2、重启php-fpm,实行psauxgrepphp-fpm失掉work历程号pid3、strace-ppid上面是我失掉的信息getcwd("/home/www/wms2.xxxx.com",4096)=26lstat("/home/www/wms2.xiaomi.com/./RWebUser.php",0x7ffff4e30a10)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xiaomi.com/protected/vendor/wms/api/RWebUser.php",0x7ffff4e30a10)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xiaomi.com/protected/vendor/wms/RWebUser.php",0x7ffff4e30a10)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xiaomi.com/protected/extensions/log/RWebUser.php",0x7ffff4e30a10)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xiaomi.com/protected/modules/rights/components/RWebUser.php",{st_mode=S_IFREG0777,st_size=2945,...})=0lstat("/home/www/wms2.xiaomi.com/protected/modules/rights/components",{st_mode=S_IFDIR0777,st_size=4096,...})=0lstat("/home/www/wms2.xiaomi.com/protected/modules/rights",{st_mode=S_IFDIR0777,st_size=4096,...})=0lstat("/home/www/wms2.xiaomi.com/protected/modules",{st_mode=S_IFDIR0777,st_size=4096,...})=0open("/home/www/wms2.xiaomi.com/protected/modules/rights/components/RWebUser.php",O_RDONLY)=5fstat(5,{st_mode=S_IFREG0777,st_size=2945,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2945,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2945,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2945,...})=0mmap(NULL,2945,PROT_READ,MAP_SHARED,5,0)=0x7fd9b4804000mmap(NULL,266240,PROT_READPROT_WRITE,MAP_PRIVATEMAP_ANONYMOUS,-1,0)=0x7fd9b442f000munmap(0x7fd9b4804000,2945)=0close(5)=0getcwd("/home/www/wms2.xxx.com",4096)=26lstat("/home/www/wms2.xxx.com/./XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/vendor/wms/api/XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/vendor/wms/XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/extensions/log/XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/modules/rights/components/XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/modules/rights/XMCCacheHttpSession.php",0x7ffff4e31060)=-1ENOENT(Nosuchfileordirectory)lstat("/home/www/wms2.xxx.com/protected/components/XMCCacheHttpSession.php",{st_mode=S_IFREG0777,st_size=2612,...})=0open("/home/www/wms2.xxx.com/protected/components/XMCCacheHttpSession.php",O_RDONLY)=5fstat(5,{st_mode=S_IFREG0777,st_size=2612,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2612,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2612,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2612,...})=0mmap(NULL,2612,PROT_READ,MAP_SHARED,5,0)=0x7fd9b4804000munmap(0x7fd9b4804000,2612)=0close(5)=0sendto(4,"get6cacd9674ad21aa083b5032b1a29"...,39,MSG_DONTWAITMSG_NOSIGNAL,NULL,0)=39recvfrom(4,0x2806d88,8196,64,0,0)=-1EAGAIN(Resourcetemporarilyunavailable)poll([{fd=4,events=POLLIN}],1,5000)=1([{fd=4,revents=POLLIN}])recvfrom(4,"VALUE6cacd9674ad21aa083b5032b1a"...,8196,MSG_DONTWAIT,NULL,NULL)=128lstat("/home/www/wms2.xxx.com/yii/web/CHttpCookie.php",{st_mode=S_IFREG0777,st_size=2772,...})=0lstat("/home/www/wms2.xxx.com/yii/web",{st_mode=S_IFDIR0777,st_size=4096,...})=0open("/home/www/wms2.xxx.com/yii/web/CHttpCookie.php",O_RDONLY)=5fstat(5,{st_mode=S_IFREG0777,st_size=2772,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2772,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2772,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2772,...})=0mmap(NULL,2772,PROT_READ,MAP_SHARED,5,0)=0x7fd9b4804000munmap(0x7fd9b4804000,2772)=0close(5)=0stat("/home/www/wms2.xxx.com/protected/extensions/redis/XMRedis.php",{st_mode=S_IFREG0777,st_size=2672,...})=0lstat("/home/www/wms2.xxx.com/protected/extensions/redis/XMRedis.php",{st_mode=S_IFREG0777,st_size=2672,...})=0lstat("/home/www/wms2.xxx.com/protected/extensions/redis",{st_mode=S_IFDIR0777,st_size=4096,...})=0lstat("/home/www/wms2.xxx.com/protected/extensions",{st_mode=S_IFDIR0777,st_size=4096,...})=0open("/home/www/wms2.xxx.com/protected/extensions/redis/XMRedis.php",O_RDONLY)=5fstat(5,{st_mode=S_IFREG0777,st_size=2672,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2672,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2672,...})=0fstat(5,{st_mode=S_IFREG0777,st_size=2672,...})=0mmap(NULL,2672,PROT_READ,MAP_SHARED,5,0)=0x7fd9b4804000munmap(0x7fd9b4804000,2672)=0close(5)=0soc

为了以后维护的方便最好是代码上都加上注释，“予人方便，自己方便”。此外开发文档什么的最好都弄齐全。我觉得这是程序员必备的素质。虽然会消耗点很多的时间。但是确实是非常有必要的。

学习php的目的往往是为了开发动态网站，phper就业的要求也涵盖了很多。我大致总结为：精通php和mysql

其实没啥难的，多练习，练习写程序，真正的实践比看100遍都有用。不过要熟悉引擎

我还是推荐用firefox ，配上firebug 插件调试js能省下不受时间。谷歌的浏览器最好也不少用，因为谷歌的大侠们实在是太天才啦，把一些原来的js代码加了一些特效。

如果你已经到这种程度了，那么你已经可以做我的老师了。其实php也分很多的区域，

我学习了一段时间后，我发现效果并不好（估计是我自身的问题）。因为一个人的精力总是有限的，同时学习这么多，会导致每个的学习时间都得不到保证。

兴趣是最好的老师，百度是最好的词典。
