1. You need to see the format of your software package,
if you have yum, you can directly Yum remove XXX
if it is RPM package, RPM - e XXX
tar package, you need to directly delete the file or make universal XXX
these are the three common ones.

2. 1. RP: if LZ is a good RP person, dig treasure and open the box. This makes a lot of money
2. Over time (I): three gems a day are indispensable, ghost territory brushes the diamond, stares at picking up the pearls, opens more numbers to collect the items needed for the sale activities
3. Good teacher (-): of course, it's the apprentice. You can get reputation in 9L Taishou area in exchange for identifier, for example, one of 70 can turn to 18J... Very rich
come on LZ, I hope you become rich --

3. This is really suspicious
first disconnect the network, and then check what's in. / M64
according to stratum + TCP..., it feels like bitcoin and other calculations, so the CPU consumption is very high, someone uses the computer to mine?

4. PS aux looks at the process number, finds the location of the virus file according to the process number, does not delete, first looks at crontab - E, whether there are abnormal tasks, and then looks at whether there are abnormal files or changes in your home directory, and whether the boot file has written tasks.... If you don't know much about Linux system, it's recommended to reload the backup data (be careful to disguise as data file). Because it's really troublesome to delete, I deleted it all afternoon
5. CentOS partition reasonable method:
1. Use SSH Remote connection tool to log in to the system, use fdisk - L command to view the disk status
2. The actual number and size of partitions can be determined according to the situation. Enter fdisk / dev / SDA and press enter to partition the hard disk
3. Enter n to create a new partition, and then enter p to create a new primary partition
select the partition number between 1-4 and enter 3
4. Here is the cylinder at the beginning of the partition. Just press enter and select the default
5. Last cylinder or + size or + size or + sizek (5367-15665, default 15665): This is to set the end cylinder of the partition, + 10g means to start from the start cylinder and end 10g backward, which is also to set the partition size to 10g, enter + 10g and enter
6. Enter P here to check whether the partition is successful or not. Enter p to enter to show whether the partition is successful
7. Create extended partition: enter N and then enter e to create extended partition and enter E
8. If you press enter here, it means that the default is selected and all the remaining space is directly occupied
9. Enter the command P here to view the current partition status
10. Let's start dividing the logical partition under the extended partition sda4! Next, as shown in the figure above, enter the command n, and the main partition is occupied. Only logical partitions can be created, while logical partitions can only be created in extended partitions. Enter n to divide the extended partitions directly
11. If you use enter directly here, you will select default
12. Enter + 5g here to indicate that the partition size is 5g, and enter + 5g
to divide another logical space, enter n enter, then enter directly, select the default starting cylinder, and enter + 5g enter to set the partition size
13. Enter P again to view the current partition status
14. The space is the same as our plan. Finally, enter w to save and exit
15. Use fdisk - L command again to check that the disk HDB has been partitioned successfully.

6. It doesn't matter. It's very convenient to use. The only difference is that the interface of Ubuntu is more beautiful than CentOS. But when you develop and use servers, there's no need to compare them. You can choose any one
7. The server.xml configuration file cannot be found in the conf folder of your tomcat, so it cannot be instantiated
