PySpider : Un puissant système de robot d'exploration de sites Web écrit par un Chinois avec une WebUI puissante. Il est écrit en langage Python, possède une architecture distribuée, prend en charge plusieurs backends de bases de données et le puissant WebUI prend en charge l'éditeur de script, le moniteur de tâches, le gestionnaire de projet et la visionneuse de résultats.

1.5.Installation
redissupervisord #supervisor的服务器端部分 启动 supervisorctl #启动supervisor的命令行窗口 # 假设创建进程pyspider01 vim /etc/supervisord.d/pyspider01.ini # 写入以下内容 [program:pyspider01] command = /root/anaconda3/envs/sbird/bin/python /root/git/pyspider/run.py directory = /root/git/pyspider user = root process_name = %(program_name)s autostart = true autorestart = true startsecs = 3 redirect_stderr = true stdout_logfile_maxbytes = 500MB stdout_logfile_backups = 10 stdout_logfile = /pyspider/supervisor/pyspider01.log # 重载 supervisorctl reload # 启动 supervisorctl start pyspider01 # 也可这样启动 supervisord -c /etc/supervisord.conf # 查看状态 supervisorctl status # output pyspider01 RUNNING pid 4026, uptime 0:02:40 # 关闭 supervisorctl shutdown
# 消息队列采用redis mkdir download;cd download wget http://download.redis.io/releases/redis-3.2.4.tar.gz tar xzf redis-3.2.4.tar.gz cd redis-3.2.4 make # 或者直接yum安装 yum -y install redis # 启动 systemctl start redis.service # 重启 systemctl restart redis.service # 停止 systemctl stop redis.service # 查看状态 systemctl status redis.service # 更改文件/etc/redis.conf vim /etc/redis.conf # 更改内容 daemonize no 改为 daemonize yes bind 127.0.0.1 改为 bind 10.211.55.22(当前服务器ip) # 重启redis systemctl restart redis.service
À ce stade, l'environnement d'exploitation à serveur unique pyspider a été construit et déployé. Démarrez localhost:5000 pour accéder à l'interface Web.
Vous pouvez également écrire un script à exécuter et vérifier l'état d'exécution dans /pyspider/supervisor/pyspider01.log.# Supervisor添加到自启动服务 systemctl enable supervisord.service # redis添加到自启动服务 systemctl enable redis.service # 关闭防火墙自启动 systemctl disable firewalld.service
