nginx,uwsgi,bottle,virtualenv在centos6上安装及性能测试

终于决定废弃java而使用python来开发网站，测试web.py的性能有点失望，看到bottle性能不错，也满足我们的需求，符合python simple的理念。测试一下生产环境的性能。
参照http://studio.zeuik.com/?p=791
测试机器:X5650X2,48G内存，centos6，包括nginx,uwsgi
压测机器:X5680X2,96G内存
web.py把cpu几乎用尽的情况下也就5000req/s左右。

1、获取安装文件
nginx-1.0.10.tar.gz
uwsgi-0.9.9.2.tar.gz
virtualenv-1.6.4.tar.gz
bottle-0.10.1.tar.gz
2、安装nginx 
tar zxvf nginx-1.0.10.tar.gz 
cd nginx-1.0.10
./configure --prefix=/usr/local/nginx --with-select_module --with-poll_module --with-http_ssl_module --with-http_gzip_static_module --with-http_flv_module --with-http_sub_module --with-http_stub_status_module --with-http_secure_link_module
make && make install

配置nginx配置文件
/usr/local/nginx/conf/nginx.conf 
worker_processes 8; #24线程cpu，8个nginx，16个uwsgi
events {
    worker_connections  10240;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen      80;
        charset     utf-8;
        root        /application/venv/bottletest;
        server_name cow.com;
 
        location / {
            include uwsgi_params;
            uwsgi_param UWSGI_PYHOME /application/venv/bottletest;
            uwsgi_param UWSGI_CHDIR /application/venv/bottletest;
            uwsgi_param UWSGI_SCRIPT index; # 对应index.py
            uwsgi_pass  127.0.0.1:8888;
        }   
 
        location ^~ /static {
            root /application/venv/bottletest;
            access_log off;
        }   
 
        location /status {
            stub_status on;
            access_log  off;
        }
    }  
}

3、安装uwsgi 
tar zxvf uwsgi-0.9.9.2.tar.gz 
cd uwsgi-0.9.9.2
mkdir /usr/local/uwsgi
cp uwsgi /usr/local/uwsgi/
cp uwsgi.xml /usr/local/uwsgi/bottletest.xml
chown root:wheel /usr/local/uwsgi/logs

配置uwsgi的xml格式配置文件
/usr/local/uwsgi/bottletest.xml 
<uwsgi>
    <socket>127.0.0.1:8888</socket>
    <home>/application/venv/bottletest</home>
    <chdir>/application/venv/bottletest</chdir>
    <python-path>/application/venv/bottletest</python-path>
    <module>[WSGI Script (index)]</module>
    <limit-as>256MB</limit-as>
    <processes>16</processes> <!-- 进程数 -->
    <master/>
    <memory/>
    <logto>/usr/local/uwsgi/logs/bottletest.log</logto>
    <daemonize>/var/log/uwsgi.log</daemonize>
    <max-requests>10000</max-requests>
</uwsgi>

4、安装virtualenv并创建bottletest应用 
tar zxvf virtualenv-1.6.4.tar.gz 
cd virtualenv-1.6.4
python setup.py install
/usr/bin/virtualenv /application/venv/bottletest
cd /application/venv/bottletest
source bin/activate

5、编辑python文件
/application/venv/bottletest/index.py 
from bottle import route, run, default_app
@route('/')
def index():
        return "hello world"
if __name__ == "__main__":
        run(host="localhost", port=8888)
else:
        application = default_app()


6、启动nginx和uwsgi 
/usr/local/nginx/sbin/nginx
/usr/local/uwsgi/uwsgi -x /usr/local/uwsgi/bottletest.xml


7、ab测试结果

总结
性能基本满意，回头测试一下模板cheetah和mako的性能。
再测试一下nginx upstreaming tornado的性能，看是否能作为nginx c module某些功能的替代品
