1、下载redis源码包，并进行解压缩操作
https://download.redis.io/releases/- [root@Redis-Ubuntu-1804-p21:~]# wget https://download.redis.io/releases/redis-5.0.14.tar.gz
- --2023-04-13 21:21:40-- https://download.redis.io/releases/redis-5.0.14.tar.gz

- [root@Redis-Ubuntu-1804-p21:~]# ls
- disk.sh issue os.version redis-5.0.14 redis-5.0.14.tar.gz system_info.sh
2、创建redis用户，创建redis目录结构并授权- [root@Redis-Ubuntu-1804-p21:~]# useradd redis -s /sbin/nologin
- [root@Redis-Ubuntu-1804-p21:~]# mkdir /app/redis/{etc,log,data,run} -p
- [root@Redis-Ubuntu-1804-p21:~]# chown redis.redis /app/redis/ -R
- [root@Redis-Ubuntu-1804-p21:~]# id redis
- uid=2006(redis) gid=2006(redis) groups=2006(redis)
- [root@Redis-Ubuntu-1804-p21:~]# ll /app/redis/
- total 24
- drwxr-xr-x 6 redis redis 4096 Apr 13 21:36 ./
- drwxr-xr-x 3 root root 4096 Apr 13 21:36 ../
- drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 data/
- drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 etc/
- drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 log/
- drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 run/
4、切换解压的到redis目录下，进行编译安装到目录 /app/redis- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]#
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# tree /app/redis

- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# make MALLOC=libc PREFIX=/app/redis/ install
5、创建命令软连接- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# tree /app/redis
- /app/redis
- ├── bin
- │ ├── redis-benchmark
- │ ├── redis-check-aof
- │ ├── redis-check-rdb
- │ ├── redis-cli
- │ ├── redis-sentinel -> redis-server
- │ └── redis-server
- ├── data
- ├── etc
- ├── log
- └── run
- 5 directories, 6 files
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# ln -s /app/redis/bin/* /usr/bin/
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# which red
- red redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
- ##方法1：手动修改
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# cp redis.conf /app/redis/etc/redis_bak.conf
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# cd /app/redis/etc/
- [root@Redis-Ubuntu-1804-p21:etc]# ll

- [root@Redis-Ubuntu-1804-p21:etc]# cat redis_bak.conf | grep ^[A-z] > redis_6379.confcat redis_bak.conf | grep ^[A-z] > redis_6379.conf

- -rw-r--r-- 1 redis redis 63115 Apr 13 22:47 redis_bak.conf
- [root@Redis-Ubuntu-1804-p21:etc]#
- ##方法2 sed修改并写入新配置文件
- [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# sed -e 's/^bind 127.0.0.1/bind 0.0.0.0/g' -e 's/^pidfile \/var\/run\/redis_6379.pid/pidfile \/app\/redis\/run\/redis_6379.pid/g' -e 's/^logfile ""/logfile "\/app\/redis\/log\/redis_6379.log"/g' -e 's/^always-show-logo yes/always-show-logo no/g' -e 's/^appendfilename "appendonly.aof"/appendfilename "appendonly_6379.aof"/g' -e 's/^dbfilename dump.rdb/dbfilename dump_6379.rdb/g' -e 's/^dir \.\//dir \/app\/redis\/data/g' redis.conf > /app/redis/etc/redis_6379.conf

7、redis service服务配置- [root@Redis-Ubuntu-1804-p21:~]# vim /etc/systemd/system/redis_6379.service

- [root@Redis-Ubuntu-1804-p21:~]# systemctl daemon-reload<br>
8、启动服务并设置开机自启动
- [root@Redis-Ubuntu-1804-p21:~]# systemctl enable --now redis_6379.service redis_6380.service redis_6381.service
- Created symlink /etc/systemd/system/multi-user.target.wants/redis_6379.service → /etc/systemd/system/redis_6379.service.

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.
