通过脚本快速获取CentOS7服务器基本系统信息
在github上找到两个快速获取CentOS7服务器基本系统信息的脚本，比较好使，分享给大家
1、monitor_system.sh
./monitor_system.sh
效果如下
其中获取公网IP的方法
curl -s https://api.myip.la
脚本如下
#!/bin/bash echo "===============================================================================" if ! wget -q --spider http://baidu.com then echo "Internet: Disconnected" else echo "Internet: Connected" fi # Check OS Release Version and Name echo "===============================================================================" name=$(</etc/os-release grep 'PRETTY_NAME=' | cut -f2 -d\") echo "OS :" "$name" # Check Architecture echo "===============================================================================" architecture=$(uname -m) echo "Architecture :" "$architecture" # Check Kernel Release echo "===============================================================================" kernelrelease=$(uname -r) echo "Kernel Release :" "$kernelrelease" # Check Hostname echo "===============================================================================" hostname=$(hostname) echo "Hostname :" "$hostname" # Check Internal IP echo "===============================================================================" internalip=$(hostname -I) echo "Internal IP :" "$internalip" # Check External IP echo "===============================================================================" externalip=$(curl -s https://api.myip.la;echo) echo "External IP :" "$externalip" # Check DNS echo "===============================================================================" nameservers=$(</etc/resolv.conf grep "nameserver" | awk '{print $2}') echo "Name Servers :" echo "$nameservers" # Check Logged In Users echo "===============================================================================" echo "Logged In users :" who # Check RAM and SWAP Usages echo "===============================================================================" echo "Memory usage :" free -h # Check Disk Usage echo "===============================================================================" df -h| grep 'Filesystem\|/dev/sda*\|/dev/mapper*\|/dev/md*\|/dev/disk*\|/dev/vda*\|/dev/dm*' >> "$tdir/diskusage.tmp" echo "Disk Usage :" cat "$tdir/diskusage.tmp" # Check Load Average echo "===============================================================================" loadaverage=$(</proc/loadavg awk '{print $1,$2,$3}') echo "Load Average :" "$loadaverage" # Check iowait echo "===============================================================================" iowait=$(iostat -c|awk '/^ /{print $4}') echo "I/O in %:" "$iowait" # Check System Uptime echo "===============================================================================" uptime=$(uptime | awk '{print $3,$4}' | cut -f1 -d,) echo "System Uptime Days/(HH:MM) :" "$uptime" echo "==============================================================================="
2、system_info.sh
./system_info.sh
效果如下
由于无wget命令，导致无法获取公网IP信息
需要手动yum install wget，安装wget命令
效果如下
脚本如下
