ProxyPool使用记录

ProxyPool启动出现错误：redis.exceptions.ConnectionError: Error 111 connecting to 127.0.0.1:6379. Connection refused.
可能与您的问题没有直接关系，但是我遇到了同样的错误，结果发现我的系统上未安装redis-server软件包,或者是没有启动。
解决方法是sudo apt-get install redis-server。别忘了开始您的服务sudo service redis-server start ，您可以使用该命令sudo service redis-server {start|stop|restart|force-reload|status}作为参考

也有可能是Redis出了问题，查看一下状态：
sudo service redis status
没运行就启动一下：
sudo service redis start
如果报错

● redis.service - LSB: starts Redis

原因可能是redis 没有正常关闭，redis.pid文件残留。
解决办法：
[root@localhost ]# vi /etc/init.d/redis
搜索【Redis is not running, buy pid file is exits】
大概在38行

 34 redis_start(){
 35         if [ -f "/www/server/redis/redis.pid" ]; then
 36                 ps -p $(cat ${PIDFILE}) > /dev/null 2>&1
 37                 if [ $? -ne "0" ]; then
 38                         echo Redis is not running, buy pid file is exits ${PIDFILE}
 39   
 40                         exit 1
 41                 else
 42                         echo "redis is running! ($(cat ${PIDFILE}))"
 43                         exit 0
 44                 fi
 45         fi
 46         echo "Starting redis server..."
 47         sudo -u redis $EXEC $CONF
 48         echo ${REDIS_PORT} > /www/server/redis/start.pl
 49         echo "Starting redis success!"
 50 }

在39行加入（exit 1之前 ）

rm -rf /www/server/redis/redis.pid && service redis restart && service redis status

然后sudo service redis restart试试查看效果
