Shell script collects the hardware information of Linux Server in batches fast implementation

2. Install the Ansible batch management system. (No, SSH remote command loop is also possible)
4. Create a new table in a common database, using the information you want to collect as a column name, and provide the ability to insert with the shell.
   
6. Bulk Install the required toolkit, Smartmontools, Dmidecode, MySQL, you can use the ansible command: Ansible all_host-s-M yum-a "Name=mysql"
7. Write the script locally.
   
   2. Get the default ip:default_ip=$ (Ifconfig|head-n 2|tail-n 1|cut-d ":"-F 2|cut-d ""-F 1)
   4. Get the name of the product, if it is a simplified version of the Linux system, you need to first install the Dmidecode Toolkit: product_name=$ (Dmidecode-t1|grep name|cut-d ""-F 3)
   6. Get the serial number of the product: serial_number=$ (Dmidecode-t1|grep serial|cut-d ""-F 3)
   8. Gets the number of CPUs: cpu_count=$ (dmidecode|grep cpu|grep version|wc-l)
   10. Get the name of the CPU: cpu_name=$ (dmidecode|grep cpu|grep version|cut-d ""-f 2-|uniq)
   12. Get memory capacity, with the free command is also very good, just no unit: mem_total=$ (cat/proc/meminfo|head-n 1|tr-s [: space:]|cut-d '-F 2-)
   14. Get Hard disk storage capacity: disk_size=$ (fdisk-l|grep "DISK/DEV/SDA" |grep-v gpt|cut-d ""-F 3-|cut-d ","-F 1)
   16. Get the hard drive model and install the Smartmontools Toolkit before using the SMARTCTL command: disk_name=$ (smartctl-a/dev/sda|grep "Product:" |awk ' {print $} ')
   18. Get Hard Drive Serial number: disk_serial_number=$ (smartctl-a/dev/sda|grep "Serial No.:" |awk ' {print $} ')
   20. Define SQL INSERT statement: sql= "INSERT into Hctt_machine_info (Default_ip,product_name,serial_number,cpu_count,cpu_name,mem_total, Disk_name,disk_serial_number,disk_size) \
       VALUES (' $default _ip ', ' $product _name ', ' $serial _number ', ' $cpu _count ', ' $cpu _name ', ' $mem _total ', ' $disk _name ', ' $ Disk_serial_number ', ' $disk _size ') "
   22. command to write login database and insert operation: MYSQL-H * * * *-uroot-p****-D hctt_sysop-e "$sql"
   24. The local script is complete.
9. Execute local script remotely using Ansible's script module: ansible-s-M script-a "****/dardware.sh"
11. Connect the database with Navicat and export it to an Excel table.
    
13. Some information about the exported discovery is empty.
    
15. command to check this machine, it is indeed a null value.
    
17. Investigation. An error was found.
    
19. View the details of the interface: sudo smartctl-d scsi-a/dev/sda
    
20. The array card needs to be installed special tools MegaRAID view.
    2. Download: Ftp://download2.boulder.ibm.com/ecc/sar/CMA/XSA/ibm_utl_sraidmr_megacli-8.00.48_linux_32-64.zip. (If the connection is not available, or if it is slow, you can find me)
    4. Installation.

       #unzip Ibm_utl_sraidmr_megacli-8.00.48_linux_32-64.zip

       #cd Linux

       # RPM-IVH lib_utils-1.00-09.noarch.rpm megacli-8.00.48-1.i386.rpm #记得两个安装包的顺序, otherwise it will go wrong.
    6. How to use: */megacli64 -ldinfo -lall -aall
       
    8. If you do not know the Megarain command path, you can find the executable file.

       sudo find/-name MegaCli64
