环境:
Vultr日本 2G内存 Centos7 x64 有公网IP
DO 1G内存 Centos7 x64 有公网IP
Linode 1G内存 Centos7 x64 有公网IP
[Vultr日本1 G内存在索引时报错:FATAL: out of memory (unable to allocate 1278738432 bytes)],可能是Vultr的VPS没有swap的原因
经测试,采集到的英文资源居多。

一.确认python版本,获取ssbc源代码,关闭防火墙
1.环境检测(Ssbc当前版本是基于django1.8.1开发,所需python环境为python2.7.5以上。)
1 2 3 4 5 6 |
[root@localhost ~]# python -V //执行python -V即可获取当前版本 Python 2.7.5 [root@localhost ~]# systemctl stop firewalld.service //关闭firewall防火墙 [root@localhost ~]# systemctl disable firewalld.service //禁止firewall防火墙开机启动 [root@localhost ~]# systemctl stop iptables.service //关闭iptables防火墙 [root@localhost ~]# systemctl disable iptables.service //禁止iptables防火墙开机启动 |
2.获取ssbc安装包并解压
1 2 3 |
[root@localhost ~]# wget https://github.com/78/ssbc/archive/master.zip [root@localhost ~]# yum -y install unzip [root@localhost ~]# unzip master.zip |
解压后你会发现在/root目录下有个文件夹ssbc-master
二.安装MariaDB,创建数据库
1.安装数据库及所需环境
1 2 3 4 5 |
[root@localhost ~]# yum -y install gcc gcc-c++ python-devel mariadb mariadb-devel mariadb-server [root@localhost ~]# cd ssbc-master [root@localhost ssbc–master]# wget https://bootstrap.pypa.io/get-pip.py [root@localhost ssbc–master]# python get-pip.py [root@localhost ssbc–master]# pip install -r requirements.txt |
2.创建ssbc数据库
1 2 3 4 5 |
[root@localhost ssbc–master]# systemctl start mariadb.service //启动数据库 [root@localhost ssbc–master]# mysql -uroot -p Enter password: (回车即可) MariaDB [(none)]> create database ssbc default character set utf8; MariaDB [(none)]> \q //创建成功后退出 |
三.安装Sphinx
1 2 3 4 |
[root@localhost ssbc–master]# yum -y install unixODBC unixODBC-devel postgresql-libs [root@localhost ssbc–master]# wget http://sphinxsearch.com/files/sphinx-2.2.9-1.rhel7.x86_64.rpm [root@localhost ssbc–master]# rpm -ivh sphinx-2.2.9-1.rhel7.x86_64.rpm [root@localhost ssbc–master]# systemctl restart sphinx.service |
四. 建立文件夹,创建以下文件夹并赋予755权限
1 2 3 |
[root@localhost ssbc–master]# mkdir -p /data/bt/index/db /data/bt/index/binlog /tem/downloads [root@localhost ssbc–master]# chmod 755 -R /data [root@localhost ssbc–master]# chmod 755 -R /tem |
五. 生成索引
1 2 3 4 |
[root@localhost ssbc–master]# systemctl restart mariadb.service //重新启动Mariadb [root@localhost ssbc–master]# systemctl enable mariadb.service //设置mariadb开启自启动 [root@localhost ssbc–master]# indexer -c sphinx.conf –all //(all 前面是空格减号减号) [root@localhost ssbc–master]# searchd –config ./sphinx.conf //(config前是空格减号减号) |
确定没有报错,继续下一步
六.Web服务器设置并启动
1 2 3 |
[root@localhost ssbc–master]# python manage.py makemigrations [root@localhost ssbc–master]# python manage.py migrate [root@localhost ssbc–master]# nohup python manage.py runserver 0.0.0.0:80 >/dev/zero & //启动网站并在后台运行 |
按回车键继续,这里可以使用其他端口然后前端再使用nginx做反向代理。手撕包菜SSBC(DHT磁力链源码) 前端使用 Nginx反向代理 80端口 图文教程
浏览器输入http://IP,网站能打开
七. 开启爬虫(workers目录下)
1 2 3 |
[root@localhost ssbc–master]# cd workers [root@localhost workers]# python simdht_worker.py #爬虫运行,等2分钟出现数据之后CTRL+C停止 [root@localhost workers]# nohup python simdht_worker.py > /dev/zero #让爬虫在后台运行 |
按回车键继
1 2 |
[root@localhost workers]# python index_worker.py #入库索引,等待10分钟出现数据后CTRL+C停止 [root@localhost workers]# nohup python index_worker.py >/dev/zero #让索引在后台运行 |
按回车键继
增加后台管理员
1 2 |
[root@localhost workers]#cd .. [root@localhost ssbc–master]# python manage.py createsuperuser |
输入管理员用户名
输入管理员邮箱
输入管理员密码
确认密码,完成
管理员登录地址:http://IP/admin
测试效果:
搜索中文英文关键字均正常
去除搜索页 右下角广告
[root@localhost ssbc-master]# cd web/static/js
[root@localhost js]# vi ssbc.js 找到如下3行,在前面添加//进行注释,保存
// document.write(‘<script src=”https://www.jiloc.com/wp-content/uploads/201608074015uMCYx.jpg”><\/script>’);
// document.writeln(“<script language=\”JavaScript\” type=\”text/javascript\” src=\”http://js.6dad.com/js/xiaoxia.js\”></script>”);
// document.writeln(“<script language=\”JavaScript\” type=\”text/javascript\” src=\”http://js.ta80.com/js/12115.js\”></script>”);
1.搜索中文报错
‘ascii’ codec can’t encode characters in position 42-43: ordinal not in range(128)
解决办法:
如果是centos7系统,修改/usr/lib64/python2.7/site.py
vi /usr/lib64/python2.7/site.py
在import sys下添加2行:
1 2 |
reload(sys) sys.setdefaultencoding('utf8') |
2.爬虫运行时 可能会遇到如下问题:
Python and Django OperationalError (2006, ‘MySQL server has gone away’)
解决方法:
http://stackoverflow.com/questions/14163429/python-and-django-operationalerror-2006-mysql-server-has-gone-away
/etc/my.cnf 在最后一行的下面添加
1 2 3 |
wait_timeout=2880000 interactive_timeout = 2880000 max_allowed_packet = 512M |
常见问题:
1.必须centos7吗?
非常建议使用centos7,centos6可能会有意想不到的错误
2.怎么查看入库的文件?
登录管理员后台,点击 Hashs
3.怎么查看每天入库了多少文件,以便清楚入库效率?
登录管理员后台,点击 Status reports
4.如何确认web服务器、采集、入库正在运行?
1 |
ps –ef|grep python |
结果里面有
python manage.py runserver 0.0.0.0:80
python simdht_worker.py
python index_worker.py
即表示正在运行。
5.如出现没有模块pygeoip,请使用命令
1 |
pip install pygeoip |
进行安装
[root@li433-14 ssbc-master]# python workers/simdht_worker.py
Traceback (most recent call last):

6.IOError: [Errno 2] No such file or directory: ‘GeoIP.dat’提示错误,解决办法:
从http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz下载GeoIP包,上传到/root/ssbc-master文件夹即可。

7.”Can’t connect to MySQL server on ’12 7.0.0.1′ (111)”,无法连接到数据库。
在运行脚本之前需要修改2个文件,因为从git上下载下来的源码里写的mariadb的端口是9306,我们这里做一下修改改成3306,否则无法启动。workers/index_worker.py:24行,search/models.py:13行,把9306替换成3306。否则会出现无法连接数据库。
可能是因为sphinx的原因造成的,由于先前的版本是先运行脚本然后再运行sphinx,所以会报错,这里我们已经将过程进行对调。
