来源：互联网发布：淘宝十元商品有哪些编辑：程序博客网时间：2024/06/09 22:58

环境为ubuntu14.04

1:下载redis 压缩包 redis-4.0.0.2.tar.gz https://redis.io/

2:解压缩：tar xzf redis-4.0.0.2.tar.gz

3:cd redis-4.0.0.2

4 make //编译

5：src/redis-cli 遇到错误,因为redis 服务没打开需要先运行redis-server redis.conf

liyafei@liyafei-OEM:~/myfile/software/redis/redis-4.0.2/src$ redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit

6：redis-server redis.conf    提示错误

10257:M 31 Oct 15:29:27.530 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

7：修改redis.conf

daemonize no修改为 daemonize yes

8：可以打开redis服务和客户端了

liyafei@liyafei-OEM:/etc$ sudo vi redis.conf
liyafei@liyafei-OEM:/etc$ redis-server redis.conf
10279:C 31 Oct 15:35:00.402 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
10279:C 31 Oct 15:35:00.402 # Redis version=4.0.2, bits=64, commit=00000000, modified=0, pid=10279, just started
10279:C 31 Oct 15:35:00.402 # Configuration loaded
liyafei@liyafei-OEM:/etc$ redis-cli
127.0.0.1:6379> exit
liyafei@liyafei-OEM:/etc$ ^C

9；为了便于处理可以将redis.conf copy到etcc目录下。liyafei@liyafei-OEM:~/myfile/software/redis/redis-4.0.2$ sudo cp redis.conf /et

liyafei@liyafei-OEM:/etc$ redis-server redis.conf
