【Redis】Redis 编译安装配置优化，多实例配置，
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

[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 log/
drwxr-xr-x 2 redis redis 4096 Apr 13 21:36 run/
3、准备编译环境，安装 build-essential （如已具备可忽略）
[root@Redis-Ubuntu-1804-p21:~]# apt-get install build-essential -y

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
6、复制并准备Redis配置文件
##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 total 72 drwxr-xr-x 2 redis redis 4096 Apr 13 22:36 ./ drwxr-xr-x 7 redis redis 4096 Apr 13 22:21 ../ -rw-r--r-- 1 root root 63088 Apr 13 22:36 redis_bak.conf [root@Redis-Ubuntu-1804-p21:etc]# vim redis_bak.conf bind 0.0.0.0 port 6379 pidfile /app/redis/run/redis_6379.pid logfile "redis_6379.log" always-show-logo no dbfilename dump_6379.rdb dir /app/redis/data appendfilename "appendonly_6379.aof" [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 [root@Redis-Ubuntu-1804-p21:etc]# sed 's/6379/6380/g' redis_6379.conf > redis_6380.conf [root@Redis-Ubuntu-1804-p21:etc]# sed 's/6379/6381/g' redis_6379.conf > redis_6381.conf [root@Redis-Ubuntu-1804-p21:etc]# chown redis.redis /app/redis/ -R [root@Redis-Ubuntu-1804-p21:etc]# ll total 84 drwxr-xr-x 2 redis redis 4096 Apr 13 22:52 ./ drwxr-xr-x 7 redis redis 4096 Apr 13 22:21 ../ -rw-r--r-- 1 redis redis 1452 Apr 13 22:51 redis_6379.conf -rw-r--r-- 1 redis redis 1452 Apr 13 22:52 redis_6380.conf -rw-r--r-- 1 redis redis 1452 Apr 13 22:52 redis_6381.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 [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# sed 's/6379/6380/g' /app/redis/etc/redis_6379.conf > /app/redis/etc/redis_6380.conf [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# sed 's/6379/6381/g' /app/redis/etc/redis_6379.conf > /app/redis/etc/redis_6381.conf [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# chown redis.redis /app/redis/ -R [root@Redis-Ubuntu-1804-p21:redis-5.0.14]# ll /app/redis/etc total 200 drwxr-xr-x 2 redis redis 4096 Apr 13 23:46 ./ drwxr-xr-x 7 redis redis 4096 Apr 13 22:21 ../ -rw-r--r-- 1 redis redis 63128 Apr 13 23:34 redis_6379.conf -rw-r--r-- 1 redis redis 63128 Apr 13 23:47 redis_6380.conf -rw-r--r-- 1 redis redis 63128 Apr 13 23:47 redis_6381.conf [root@Redis-Ubuntu-1804-p21:redis-5.0.14]#
7、redis service服务配置
[root@Redis-Ubuntu-1804-p21:~]# vim /etc/systemd/system/redis_6379.service [Unit] Description=Redis persistent key-value database After=network.target [Service] ExecStart=/app/redis/bin/redis-server /app/redis/etc/redis_6379.conf --supervised systemd ExecStop=/bin/kill -s QUIT Type=notify User=redis Group=redis RuntimeDirectory=redis RuntimeDirectoryMode=0755 LimitNOFILE=65536 [Install] WantedBy=multi-user.target
