Redis installation under mac

1. Install redis

1. Go to the official website to download the latest version of redis, I downloaded 3.0.3

http://redis.io/

2. Copy redis-3.0.3 to the /usr/local directory

3. Unzip sudo tar -zxf redis-3.0.3.tar.gz

4. Enter the decompressed directory cd redis-3.0.3

5. Compile and test: sudo make test

 

6. Compile and install: sudo make install

7. Start the service: ./redis-server

Under mac, redis installation and configuration

 

(PS: This interface reminds me of Knight's Xing, a Mud (MUD) game I played in 1999) At this point there is a warning that there is no configuration file. We need to make a progress configuration. 

Two, placement 

Configuration:

1. Create a directory redis under /usr/local/. Create bin, etc, db three directories in the redis directory

sudo mkdir /usr/local/redis/bin

....

 

2. Copy mkreleasehdr.sh, redis-benchmark, redis-check-dump, redis-cli, redis-server in the src directory to

bin directory

sudo mv /usr/local/redis3.0.3/mkreleasehdr.sh /usr/local/redis/mkreleasehdr.sh 

...... 

 

3. Under etc, refer to the redis.conf in the original redis3.0.3 directory, and create a new redis.conf

cd /usr/local/redis/etc

vim redis.conf

 

Modify redis.conf as follows:

 

#Modify to guard mode

daemonize=yes

#Set the process lock file

pidfile /usr/local/redis/redis.pid

#port

port 6379

#Client timeout

timeout 300

# log level

loglevel debug

#log file location

logfile /usr/local/redis/log-redis.log

#设置数据库的数量,默认数据库为0,可以使用SELECT <dbid>命令在连接上指定数据库id

databases 8

##指定在多长时间内,有多少次更新操作,就将数据同步到数据文件,可以多个条件配合

#save <seconds> <changes> 

#Redis默认配置文件中提供了三个条件:

save 900 1

save 300 10

save 60 10000

#指定存储至本地数据库时是否压缩数据,默认为yes,Redis采用LZF压缩,如果为了节省CPU时间,

#可以关闭该#选项,但会导致数据库文件变的巨大

rdbcompression yes

#指定本地数据库文件名

dbfilename dump.rdb

#指定本地数据库路径

dir /usr/local/redis/db/

#指定是否在每次更新操作后进行日志记录,Redis在默认情况下是异步的把数据写入磁盘,如果不开启,可能

#会在断电时导致一段时间内的数据丢失。因为 redis本身同步数据文件是按上面save条件来同步的,所以有

#的数据会在一段时间内只存在于内存中

appendonly no

#指定更新日志条件,共有3个可选值: 

#no:表示等操作系统进行数据缓存同步到磁盘(快) 

#always:表示每次更新操作后手动调用fsync()将数据写到磁盘(慢,安全) 

#everysec:表示每秒同步一次(折衷,默认值)

appendfsync everysec

 

4、如果用户不是root,那么为了减少麻烦,可以将目录的所有者修改为本人:

 

chown -R xxxx redis

 

5、保存后,启动redis

 

./bin/redis-server etc/redis.conf

6. View log files 

tail -f log-redis.log

At this point, redis installation and configuration are complete! Ready to try.
