Apache,httpd: apr_sockaddr_info_get() failed for apache

<Category: Linux, 流媒体>

上架前夜,ams不给力,居然起不来了,请求提示,empty response,急死人啊。

转:http://blog.csdn.net/lyjtynet/article/details/4213173
httpd: apr_sockaddr_info_get() failed for hoteel
httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
我在service httpd restart的时候提示上述信息的。虽然启动成功了,但是也是很郁闷的。
这是因为我在配置DNS的时候hostname hoteel造成的。
重新hostname localhost就可以了。
我在网上找来一些有关这方面的信息,就顺便贴在这里了。
1
在启动 httpd 时出现
Starting httpd: httpd: apr_sockaddr_info_get() failed for MYHOST
httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName.
这个问题应该是没有在 /etc/httpd/conf/httpd.conf 中设定 ServerName 所以它会用主机上的名称来取代,首先会去找 /etc/hosts 中有没有主机的定义。
所以要解决这个问题可以设定 ServerName 或者在 /etc/hosts 中填入自己的主机名称 MYHOST,像这样:
>vi /etc/hosts
127.0.0.1 localhost.localdomain localhost MYHOST

2
在Linux下安装完Apache 2.2.6,启动HTTP服务就报错,似乎不影响服务的使用,但是也挺别扭的。

[root@linux http]# ./apachectl start
httpd: apr_sockaddr_info_get() failed for linux(在BSD上是apr_sockaddr_info_get() failed for freebsdla)
httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName

经分析发现是apache的conf目录下的配置文件httpd.conf中关于hostname设置和/etc/sysconfig/network中的HOSTNAME设置不统一导致的,修改成统一的主机名即可解决该问题。

注:/etc/sysconfig/network 默认主机名是:HOSTNAME=localhost.localdomain

PS:网上有这种办法,似乎是没用的,因为我认为apache在编译安装过程中会编译ARP的,因此下述操作有点多余。

apr 和apr-util包含在Apache httpd的发行源代码中,并且在绝大多数情况下使用都不会出现问题。当然,如果apr或apr-util的1.0或1.1版本已经安装在你的系统中了, 则必须将你的apr/apr-util升级到1.2版本,或者将httpd单独分开编译。要使用发行源代码中自带的apr/apr-util源代码进行安 装,你必须手动完成:

# 编译和安装 apr 1.2

apr
./configure –prefix=/x/httpd/apr
make
make install

apr-util
./configure –prefix=/x/httpd/apr_util –with-apr=/x/httpd/apr
make
make install

apache
./configure –prefix=/x/httpd/apache2 /
–enable-so /
–enable-cgi /
–enable-rewrite /
–enable-mods-shared=all /
–with-apr=/x/httpd/apr /
–with-apr-util=/x/httpd/apr_util

LDFLAGS=”-L/usr/lib64 -L/lib64″

本机正确设定说明 必须为同一的

[root@spring ~]# nl /etc/hosts
1 # Do not remove the following line, or various programs
2 # that require network functionality will fail.
3 127.0.0.1 localhost.localdomain spring

[root@spring ~]# nl /etc/sysconfig/network
1 NETWORKING=yes
2 NETWORKING_IPV6=no
3 HOSTNAME=spring
4 #GATEWAY=192.168.8.1

[root@spring ~]# less /etc/httpd/conf/httpd.conf|grep ServerName
# ServerName gives the name and port that the server uses to identify itself.
#ServerName www.example.com:80
ServerName 127.0.0.1

mysql开启远程访问权限错误

<Category: mysql>

mysql需要开放远程访问端口,结果。。
mysql> update user set host =’%’ where user =’root’;
ERROR 1062 (23000): Duplicate entry ‘%-root’ for key ‘PRIMARY’

root用户好几个,有几个没有密码
mysql> update user set password = PASSWORD(‘xxx’) where user=’root’
-> ;
删除最后一个root用户:
localhost root

然后确保有一个%就可以了。

elasticsearch插件bug fix

<Category: Diving Into ElasticSearch, 小道消息>

lucene4变化不少:http://blog.mikemccandless.com/2012/07/lucene-400-alpha-at-long-last.html
自定义的analyzer的要求也更加严格,之前写的几个插件,都报错了。
错误具体表现在第一次分词没有问题,第二次及后续的分词都是空,感谢各位网友的积极响应和测试反馈,谢谢。

具体是什么原因呢?

仔细研究了下代码,发现reset多加了一个参数,汗,fix如下:

–    public void reset(Reader input) throws IOException {
+    public void reset() throws IOException {

 

受影响的插件:pinyin、string2int、stconvert

这次都是按jdk6重新编译的,上次反映的jdk7的问题也一并解决了。
