记录php5.4与php-redis冲突的解决

最近由于update了ubuntu的源,导致原来新源与本地系统库一些lib冲突,导致系统桌面显示异常,后来只有重装,新安装了php5.4.9,还安装了redis,php-redis扩展,php-redis扩展2,10。但把原来的项目一放上去,就报nginx 502错误(nginx 502错误真是个很头疼的问题)。打开nginx日志查看

[error] 29229#0: *1403 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server:

不知道所云。后来打开php-fpm错误日志,得到的log日志

[08-Oct-2013 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

可以确定的一点,是php-fpm在一个时间点后重启了一个进程。还是毫无头绪。在网上搜了一大遍,有个有用的跟踪方法。

1、设置php-fpm,只起一个work进程

2、重启php-fpm, 执行ps aux| grep php-fpm 得到work进程号pid

3、strace -p pid

--- SIGSEGV (Segmentation fault) @ 0 (0) ---

Process 6011 detached


可以看得出,在执行XMRedis后进程6011 就死掉了。基本可以定位是php-redis出了问题。

继续追查最终发现了有段代码问题


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 (RedisException $e) {

throw new CHttpException(500, "Redis occurs an error:" . $e->getMessage());

}

}

用红色的代码那段,就会报502错误,而用绿色代码这段就没问题。


setOption 这个是个神马东西呢?查了下php-redis api


$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_NONE); // don't serialize data 不序列化数据

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_PHP); // use built-in serialize/unserialize 用php内置的序列化

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_IGBINARY); // use igBinary serialize/unserialize 用扩展IGBINARY序列化

$redis->setOption(Redis::OPT_PREFIX, 'myAppName:'); // use custom prefix on all keys redis key前缀


$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_PHP); 用此就报502


为什么用php内置的序列化就会出错呢?到底发生了什么?

后来又安装了IGBINARY 扩展,还是不行。最后把php-redis安装了最新的版本2.24,再运行,就完全没问题了。
