1.安装

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

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 ../

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 ../

性能调优（可选）

#ulimit -SHn 65535

2.启动

#httpsqs -d -p 1218 -x /data0/queue

请使用命令“killall httpsqs”、“pkill httpsqs”和“kill `cat /tmp/httpsqs.pid`”来停止httpsqs。

　　注意：请不要使用命令“pkill -9 httpsqs”和“kill -9 httpsqs的进程ID”来结束httpsqs，否则，内存中尚未保存到磁盘的数据将会丢失。

3.调用

(1)、入队列（将文本消息放入队列）：

　　HTTP GET 协议（以curl命令为例）：

curl "http://host:port/?name=your_queue_name&opt=put&data=经过URL编码的文本消息&auth=mypass123"

　　HTTP POST 协议（以curl命令为例）：

curl -d "经过URL编码的文本消息" "http://host:port/?name=your_queue_name&opt=put&auth=mypass123"

(2)、出队列（从队列中取出文本消息）：

　　HTTP GET 协议（以curl命令为例）：

curl "http://host:port/?charset=utf-8&name=your_queue_name&opt=get&auth=mypass123"

curl "http://host:port/?charset=gb2312&name=your_queue_name&opt=get&auth=mypass123"
