1. Download redis
download link:
English version: https://redis.io/download
Chinese version: www.redis.cn/download.html
Download the redis installation package and upload it to the linux directory. This installation is redis-3.0.7.tar.gz.
[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]#
[root@xiaohao-db01 vnum]# 2. Install redis
1. Unzip redis-3.0.7.tar.gz
Decompression command: tar -zxvf redis-3.0.7.tar.gz
After decompression, the redis directory can be seen: redis-3.0.7
[root@xiaohao-db01 vnum]# tar -zxvf redis-3.0.7.tar.gz^C
[root@xiaohao-db01 vnum]#
[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz redis-3.0.7 redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]# 2. Compile the redis decompressed file.
Enter the directory redis-3.0.7 and execute the make command.
[root@xiaohao-db01 vnum]#
[root@xiaohao-db01 vnum]# cd redis-3.0.7
[root@xiaohao-db01 redis-3.0.7]# make
cd src && make all
make[1]: Entering directory `/vnum/redis-3.0.7/src'
rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-dump redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html

(cd lua && make clean) > /dev/null || true
(cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true
(rm -f .make-*)
make[2]: Leaving directory `/vnum/redis-3.0.7/deps'

echo WARN=-Wall -W >> .make-settings
echo OPT=-O2 >> .make-settings
echo MALLOC=jemalloc >> .make-settings
echo CFLAGS= >> .make-settingsThe compilation process shows that the content is old, the compilation is successful, and the final display is generally as follows:
LINK redis-check-dump
CC redis-check-aof.o
LINK redis-check-aof
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/vnum/redis-3.0.7/src'3. Install the redis file.
Go to the redis-3.0.7/src directory and execute the make install command.

[root@xiaohao-db01 src]# 4. Create a new folder redis in the directory redis-3.0.7, and copy the configuration files related to redis to this directory.
This is to put the redis related execution files in the same special directory for easy operation. Optional.
[root@xiaohao-db01 redis-3.0.7]# mkdir redis
[root@xiaohao-db01 redis-3.0.7]# ls

[root@xiaohao-db01 redis-3.0.7]# After the copy is completed, the redis directory is as follows:
[root@xiaohao-db01 redis-3.0.7]# cd ..
[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz redis-3.0.7 redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]# cd redis-3.0.7
[root@xiaohao-db01 redis-3.0.7]# cd redis
[root@xiaohao-db01 redis]# ls
mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-dump redis-cli redis.conf redis-sentinel redis-server redis-trib.rb
[root@xiaohao-db01 redis]# Third, test redis.
1. Start redis.
Start command: /vnum/redis-3.0.7/redis/redis-server /vnum/redis-3.0.7/redis/redis.conf &
It is recommended to modify the configuration file first, the default background start: daemonize yes

26183:M 19 Apr 14:58:16.468 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

After installing the file, you can change the redis.conf configuration to enable common functions such as local persistence and active/standby synchronization. This will not be written here for the time being.
