Httpsqs的安装以及安装过程错误的解决方法 转

需求 ：进行商品搜索的时候，要从索引中进行搜索，由于后台要更新商品和插入商品，当时考虑到了怎么来插入新的索引和更新索引的问题，通过讨论，大家决定用Httpsqs这个消息中间来通知插入新索引和删除索引最后合并索引，来做到商品信息的实时更新。

下面我来讲一下Httpsqs的安装过程 ，以及在安装过程遇到的问题。

准备工作：

你需要准备一个虚拟机这里我们采用VMware7.1，

Linux采用CentOS5.4 可以到http://vault.centos.org/5.4/isos/i386/CentOS-5.4-i386-bin-DVD.torrent这个网址进行下载。

安装 httpsqs

在安装httpsqs之前要安装

libevent-2.0.12-stable.tar.gz和okyocabinet-1.4.47.tar.gz  

ulimit -SHn 65535

1、安装libevent-2.0.12-stable.tar.gz

wget http://httpsqs.googlecode.com/files/libevent-2.0.12-stable.tar.gz##下载
tar zxvf libevent-2.0.12-stable.tar.gz##解压
cd libevent-2.0.12-stable/
./configure --prefix=/usr/local/libevent-2.0.12-stable/
make
make install
cd ../

安装tokyocabinet-1.4.47.tar.gz

wget http://httpsqs.googlecode.com/files/tokyocabinet-1.4.47.tar.gz
tar zxvf tokyocabinet-1.4.47.tar.gz
cd tokyocabinet-1.4.47/
./configure --prefix=/usr/local/tokyocabinet-1.4.47/
#注：在32位Linux操作系统上编译Tokyo cabinet，请使用./configure --enable-off64代替./configure，可以使数据库文件突破2GB的限制。
#./configure --enable-off64 --prefix=/usr/local/tokyocabinet-1.4.47/
make
make install
cd ../

当执行第二步骤的会出错，是由于缺少bzip2-1.0.6.tar.gz

下面进行安装

http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz安装开始；
wget  http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
tar -xvzf bzip2-1.0.6.tar.gz
cd bzip2-1.0.6.
make
 make install

在重复安装tokyocabinet-1.4.47.tar.gz还是失败，由于缺少zlib-1.2.5.tar.gz

下面进行安装

http://www.winimage.com/zLibDll/zlib-1.2.5.tar.gz安装开始；
wget  http://www.winimage.com/zLibDll/zlib-1.2.5.tar.gz
tar -xvzf zlib-1.2.5.tar.gz
cd zlib-1.2.5.
./configure
make
sudo make instal

继续第2步骤 OK

3、安装httpsqs-1.7.tar.gz

wget http://httpsqs.googlecode.com/files/httpsqs-1.7.tar.gz
tar zxvf httpsqs-1.7.tar.gz
cd httpsqs-1.7/
make
make install
cd ../

如果安装成功 执行httpsqs –h 会出现

但是没有 出现的是：

error while loading shared libraries: /usr/local/tokyocabinet-1.4.47/lib/libtokyocabinet.so.9: cannot restore segment prot after reloc: Permission denied

在google一下，说是没有建立它的软连接：

ln -s /usr/local/tokyocabinet-1.4.47/lib/libtokyocabinet.so.9 /usr/lib/libtokyocabinet.so.9

可是做了，还是报错 继续google，解决办法为：

vi /etc/sysconfig/selinux file
修改SELINUX=disabled

然后重启

再来一次

httpsqs -h
