一：paramiko模块的安装
paramiko模块的安装
环境设置
Linux系统为 Centos 6.7
Python环境为 Python 3.6
连接Unix类服务器模块: paramiko
这里我们采用pip3命令安装，会自动下载缺失的模块
[oracle@jumplinux01 bin]$ ./pip3 install paramiko

问题：在linux环境下，安装完python3.6.2后，如果发现并没有pip3，需要手动安装
[root@jumplinux01 ~]# wget https://files.pythonhosted.org/packages/69/81/52b68d0a4de760a2f1979b0931ba7889202f302072cc7a0d614211bc7579/pip-18.0.tar.gz

验证安装
import paramiko 无报错说明安装导入成功
[oracle@jumplinux01 bin]$ python

二：使用paramiko监控Oracle alert日志
环境设置
Linux系统为 Centos 6.7
Python环境为 Python 3.6
连接Unix类服务器模块: paramiko
使用的命令
我们使用grep命令来判断alert日志中是否有ORA Error及Checkpoint报警
监控alert日志程序
如下程序使用paramiko连接linux/Unix服务器后查看alert日志查看报警关键字，当发现错误时输入结果
程序名称为:checkoraclelog.py
[oracle@jumplinux01 script]$ vim checkoraclelog.py
#!/usr/bin/python
#coding=utf8
import paramiko
def oraclelog(ssh,path):
alert_log=[]
command='grep -E \'ORA-|Checkpoint|Error\' '+path
stdin,stdout,stderr=ssh.exec_command(command)
err=stderr.readlines()
if len(err) != 0:
print (err)
return False
else:
stdout_content=stdout.readlines()
if len(stdout_content)!=0:
result='\n'.join(stdout_content)
result= 'Oralce log on '+hostname+ ' have errors\n'+'The log path is '+path+'\n'+result
alert_log.append(result)
return alert_log
else:
return 'noerror'
if __name__ == '__main__':
hostname='192.168.2.222'
username='root'
password='******'
try:
#使用SSHClient方法定义ssh变量
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
#连接目标服务器
ssh.connect(hostname=hostname,port=22,username=username,password=password)
path='/u01/app/oracle19/diag/rdbms/cjcdb01/cjcdb01/trace/alert_cjcdb01.log'
alert_log=oraclelog(ssh,path)
ssh.close()
if alert_log:
if alert_log !='noerror':
for i in alert_log:
print (i)
else:
print ('There is no ORA- error on '+hostname)
except Exception as e:
print (hostname+' '+str(e))
运行效果：
[oracle@jumplinux01 script]$ python checkoraclelog.py
Oralce log on 192.168.2.222 have errors
The log path is /u01/app/oracle19/diag/rdbms/cjcdb01/cjcdb01/trace/alert_cjcdb01.log
