操作系统
CentOS Linux release 7.0.1406 (Core)
Python环境
Python安装
安装依赖：
yum install gcc # 安装python必须
yum install zlib # 以下四个安装setuptools必须，如果安装在python后，则需要重新make python
yum install zlib-devel
yum install openssl
yum install openssl-devel
cd Python-2.7.13
./configure --prefix=/python2.7
make
make install
配置环境变量
# vi ~/.bash_profile
export PATH=/python2.7/bin:$PATH
安装pip
依赖：setuptools
依赖：six-1.10.0.tar.gz packaging-16.8.tar.gz pyparsing-2.2.0.tar.gz appdirs-1.4.3.tar.gz
cd pip-9.0.1
# python setup.py install
安装pyspider
从github下载最新版pyspider
依赖系统包：
tcl protobuf libcurl-devel libxslt-devel libxml2
使用yum install 安装他们。。。
cd pyspider # 安装依赖包并安装 pip install -r requirements.txt python setup.py install
由于requirements.txt中的mysql-connector无法下载，所以选择安装其它版本的mysql-connector
pip install mysql-connector==2.1.4
安装mysql数据库
用yum安装完后,参考http://www.itnose.net/detail/6310643.html，完成数据库的安装。
# 重启mysql
service mysqld restart
# mysql -u root
# 修改root密码
mysql> use msyql
mysql> update user set password=password('123456') where user='root';
# 创建数据库并授权
mysql> create database taskdb;
mysql> create database projectdb;
mysql> create database resultdb;
mysql> create user 'pyspider'@'%';
mysql> create user pyspider@'localhost' identified by 'pyspider-pass';
mysql> grant select,insert,update,references,delete,create,drop,alter,index,trigger,create view,show view,execute,alter routine,create routine,create temporary tables,lock tables,event on taskdb.* to 'pyspider'@'%';
mysql> grant select,insert,update,references,delete,create,drop,alter,index,trigger,create view,show view,execute,alter routine,create routine,create temporary tables,lock tables,event on projectdb.* to 'pyspider'@'%';
mysql> grant select,insert,update,references,delete,create,drop,alter,index,trigger,create view,show view,execute,alter routine,create routine,create temporary tables,lock tables,event on resultdb.* to 'pyspider'@'%';
mysql> flush privileges;
修改配置文件(为集群做准备)
vi /etc/my.cnf
bind-address = 0.0.0.0
# 重启数据库
service mysqld restart
安装redis
下载redis，并解压到/root/training目录下
安装redis
cd /root/training/redis-2.8.12 make make test make install # 为集群做准备 cd /root/training/redis-3.2.8 cp redis.conf /etc/ vi /etc/redis.conf bind 0.0.0.0 # 启动 redis redis-server /etc/redis.conf &
启动成功标志：The server is now ready to accept connections on port 6379
防火墙
查看防火墙状态：
firewall-cmd --state
自己两条配置：
iptables -A INPUT -s 127.0.0.1 -p tcp --dport 6379 -j ACCEPT
iptables -A INPUT -p tcp --dport 6379 -j DROP
关闭firewall：
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
如果不会配置，最好停止防火墙。
安装phantomjs
下载：wget https://bbuseruploads.s3.amazonaws.com/fd96ed93-2b32-46a7-9d2b-ecbc0988516a/downloads/396e7977-71fd-4592-8723-495ca4cfa7cc/phantomjs-2.1.1-linux-x86_64.tar.bz2?Signature=guF7TAUW11qr9nZXcTBHu7dg1ds%3D&Expires=1488510600&AWSAccessKeyId=AKIAIVFPT2YJYYZY3H4A&versionId=null&response-content-disposition=attachment%3B%20filename%3D%22phantomjs-2.1.1-linux-x86_64.tar.bz2%22
下载phantomjs-2.1.1-linux-x86_64.tar.bz2到/root目录下，解压
将 phantomjs/bin目录下的phantomjs文件拷贝到/python2.7/bin目录下
配置文件
====================================================================
pyspider配置文件如下：
{
"taskdb": "mysql+taskdb://pyspider:pyspider-pass@localhost:3306/taskdb",
"projectdb": "mysql+projectdb://pyspider:pyspider-pass@localhost:3306/projectdb",
"resultdb": "mysql+resultdb://pyspider:pyspider-pass@localhost:3306/resultdb",
"message_queue": "redis://localhost:6379/db",
"webui": {
"port":5555,
"username": "pyspider",
"password": "pyspider-pass",
"need-auth": true
}
}
=========================================
# 为安全起见，我们新建一个普通用户来存储配置文件
useradd -md /pyspider pyspider
# 保存配置文件
/pyspider/config.json
# 权限设置
chown -R pyspider:pyspider /pyspider
chmod 400 config.json
启动pyspider
启动pyspider
/anaconda2/bin/pyspider -c /pyspider/config.json
结果如下：

安装supervisor，监控所有进程
supervisor用来监控pyspider进程，如果停止则立即启动，下载supervisor-3.3.1到/root目录下，并解压。
cd /root/supervisor-3.3.1 python setup.py install
或
pip install supervisor
创建默认的配置文件并设置
