Centos7下搭建H3C log服务器

rsyslog+H3C

安装rsyslog服务器

关闭防火墙

bash 复制代码

systemctl stop firewalld && systemctl disable firewalld

关闭selinux

bash 复制代码

sed -i 's/enforcing/disabled/' /etc/selinux/config && setenforce 0

centos7服务器，通过yum安装rsyslog

bash 复制代码

yum -y install rsyslog

建立日志存放路径

bash 复制代码

mkdir -p /data/h3c/log

建立日志文件

bash 复制代码

touch /data/h3c/log/switch_log

修改rsyslog配置文件

bash 复制代码

vi /etc/rsyslog.conf

bash 复制代码

#去掉注释
$ModLoad imudp 
$UDPServerRun 514                    #允许客户端通过udp:514 端口连接
$IncludeConfig /etc/rsyslog.d/*.conf
*.info;mail.none;authpriv.none;cron.none                /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
*.emerg                                                 *
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log

#添加以下内容
SYSLOGD_OPTIONS="-c 2 -r -x -m 180"
KLOGD_OPTIONS="-x"
local7.info /data/h3c/log/switch_log

交换机配置

配置每台交换机的日志接收，需要登录每台交换机执行以下命令（info-center loghost 172.16.0.10，这边IP需要配日志服务器的IP），操作都是重复的，利用python脚本一键执行即可：

bash 复制代码

system-view
info-center loghost 172.16.0.10
info-center enable 
save force

在centos7服务器，创建python脚本执行配置，

创建python脚本文件：h3c_script.py

bash 复制代码

vi h3c_script.py

赋权：

bash 复制代码

chmod +x h3c_script.py

脚本内容如下：

python 复制代码

#!/usr/bin/env python3

#先安装pip3 install paramiko
import paramiko

# 创建SSH客户端
ssh_client = paramiko.SSHClient()

# 自动添加主机密钥（选项，根据需求使用）
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 交换机的IP地址列表
switches = [
    # 用您实际的交换机IP地址替换这些

    ]  


# SSH登录凭据，填交换机登录账户密码
username = "账号"
password = "密码"

# 连接每台交换机并执行命令
for switch_ip in switches:
    try:
        ssh_client.connect(switch_ip, username=username, password=password)
        ssh_shell = ssh_client.invoke_shell()

        # 执行命令
        ssh_shell.send("system-view\n")
        ssh_shell.send("info-center loghost 172.16.0.10\n")
        ssh_shell.send("info-center enable\n")
        ssh_shell.send("save force\n")

        # 等待命令执行完成
        while not ssh_shell.recv_ready():
            pass

        # 关闭连接
        ssh_client.close()

        print(f"Commands executed on {switch_ip}")
    except Exception as e:
        print(f"Failed to execute commands on {switch_ip}: {str(e)}")

# 关闭SSH客户端
ssh_client.close()

配置完，登录服务器，测试日志接收情况

bash 复制代码

 tail -f /data/log/h3c/switch_log
