centos6.4 uWSGI + nginx + bottle (下)
配置uWSGI的服务方式启动
承接上文 centos6.4 uWSGI + nginx + bottle (上) ,此文主要是说配置uWSGI（将之前的/etc/rc.local 的追加script删除）
vi /etc/uwsgi3031.ini
[uwsgi] socket = 127.0.0.1:3031 master = true vhost = true no-stie = true workers = 2 reload-mercy = 10 vacuum = true max-requests = 1000 limit-as = 512 buffer-sizi = 30000 pidfile = /var/run/uwsgi3031.pid daemonize = /var/www/test_app/uwsgi3031.log
vi /etc/init.d/uwsgi3031
#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for uwsgi webserver on Debian. Place in /etc/init.d and

exit 3

esac
exit 0 在这个目录下一定要有执行权限
chmod +x /etc/init.d/uwsgi3031配置一下开机启动服务
### add service chkconfig --add uwsgi3031 chkconfig uwsgi3031 on最后重启机器来试一下吧！
多个站点配置
按照上面的方法来配置多一个uWSGI，只不过是端口不同而已，以及在nginx的配置文件加入相应该的server节点就可以了，我下面直接来一个示例，将之前的代码复制一份叫test_app2，纯上代码的:
vi /etc/uwsgi9099.ini
[uwsgi] socket = 127.0.0.1:9099 master = true vhost = true no-stie = true workers = 2 reload-mercy = 10 vacuum = true max-requests = 1000 limit-as = 512 buffer-sizi = 30000 pidfile = /var/run/uwsgi9099.pid daemonize = /var/www/test_app2/uwsgi9099.log
vi /etc/init.d/uwsgi9099
#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for uwsgi webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f uwsgi defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add uwsgi'

# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the uwsgi web server
# Description: starts uwsgi using start-stop-daemon
### END INIT INFO
# Author: licess

DESC="uwsgi daemon"
NAME=uwsgi9099
DAEMON=/usr/bin/uwsgi
CONFIGFILE=/etc/$NAME.ini
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON $CONFIGFILE || echo -n "uwsgi already running"
}
do_stop() {
$DAEMON --stop $PIDFILE || echo -n "uwsgi not running"
rm -f $PIDFILE
echo "$DAEMON STOPED."
}
do_reload() {
$DAEMON --reload $PIDFILE || echo -n "uwsgi can't reload"
}
do_status() {
ps aux|grep $DAEMON
}
case "$1" in
status)
echo -en "Status $NAME: \n"
do_status
;;
start)
echo -en "Starting $NAME: \n"
do_start
;;
stop)
echo -en "Stopping $NAME: \n"
do_stop
;;
reload|graceful)
echo -en "Reloading $NAME: \n"
do_reload
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload}" >&2
exit 3
;;
esac
exit 0
chmod +x /etc/init.d/uwsgi9099
vi /etc/nginx/conf.d/default.conf
## add one more server node, append this
server {
listen 9999;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main;
location / {
include uwsgi_params;
uwsgi_param UWSGI_PYHOME /var/www/test_app2;
uwsgi_param UWSGI_CHDIR /var/www/test_app2;
uwsgi_param UWSGI_SCRIPT app;
uwsgi_pass 127.0.0.1:9099;
# root /usr/share/nginx/html;
# index index.html index.htm;
}
}
In the terminal:
## add it to the service chkconfig --add uwsgi9099 chkconfig uwsgi9099 on ## start the service service uwsgi9099 start ## restart the nginx service nginx restart
## you can try it out with curl or browser curl http://127.0.0.1:9999/
简单的性能测试
我们就用Apache 的ab command line, ab 在linux/unix当中是默认是安装的，直接就可以用了，windows系统的话要另装。下面就直接来一下简单的压力测试吧！
#------------------------------------------------
#memory : 1024 MB
#cpu: Intel Core x 1
#尝试总共发10000个请求，10个并发(也就是相当于模拟10个人同时访问)

在局域网内80％ 的请求可以在 10 毫秒内响应，虚似的机器配置比较低(我的电脑也是3年前的没有办法)，总共10000个请求还好，20000的话就比较免强了，有fail的可能了，再多就不行了。整体来说还算可以的。
