CentOS Server Installation notes (1)

CentOS Server Installation notes (1) some time ago, the Department applied for two new servers and added the original old server to three servers. Boss handed me the whole task of organizing the server. I think this is not a formal employee, so I can do this, so I can't afford it. I didn't play much in Linux. At first, I just wanted to have a good experience with the 3D desktop. Later I was not very helpful, because I often killed and reinstalled the system when I was unhappy. Ubuntu, openSUSE, FreeBSD, and Gentoo all played, it's good to see if it's windows. I have no idea how to directly install the server this time. I used it all in the end, but it was still a bit difficult. I wrote it down for commemorative purposes, you can also write your resume in the future as "system O & M". You are welcome to criticize and correct it ~ First, select the server system version. Find the latest version 6.3X86 _ 64 and install it on a dial. 1 hardware configuration server configuration description S1 [new] Dell T320 (2 tb sata, 16 gb ram) s2 [new] Dell T320 (2 tb sata, 32 gb ram, 2 TB Raid) for user authentication, svn, and testing platforms) used as the database server S3 [old] Dell T310 (500g sata, 8g ram) for training version control, database server and Public Data Management 2 IP address planning vro use 192.168.1.1, retain 192.168.1.1 ~ 192.168.1.9 is used as the server and so on.

For simplicity, /var and so on are not separately separated into S3 to keep the original partition and replace the original Linux (for simplicity). 4 software planning software version S1 (main server) S2 (db server) s3 (old) JDK 1.6.38 ●● Xfce ●●● openLDAP ●apache ●● Svn ●● Oracle 11g R2 ●● Squid ●5 CentOS6.3 _ x86_64 (64-bit version) is installed on the system ), use a CD for installation.

Select "create custom partition layout" as the partition settings ", select free space for partitioning. 3. You do not need to set the servers that contain Raid, A non-Raid disk is automatically loaded. 4. The installation system is booted to/dev/sda 5. The system version is Minimal (Minimal installation). 6. The installation is complete. After the disc is popped up, take it out and restart. Note: many configuration files have been configured during system installation. You can use a USB flash drive in ext4 format to copy the files. After the files are inserted to the server, they must be manually mounted. First, determine the device name: fdisk-l and then mount: mkdir/mnt/usb mount/dev/sdb1/mnt/usb or use tomcat to build a website on a remote computer, put the file in.
