Xiaobian to share with you the example analysis of redis installation, settings, start and stop under mac, I believe most people still don't know how to understand, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go and understand it together!

You need to download the release version, download address:

http://download.redis.io/releases/

What I downloaded here:

http://download.redis.io/releases/redis-3.2.5.tar.gz

Extract it to/usr/local/redis and execute the following commands:

cd /usr/local/redissudo make test

sudo make install

Start redis-server

redis-server

As shown above, redis-server starts successfully and listens on port 6379.

Description of common commands

redis-server redis

redis-cli redis client

redis-benchmark redis performance testing tool

redis-check-aof AOF file repair tool

redis-check-rdb RDB file repair tool

Start and Stop Server Start

default startup

As above, the command redis-server starts the redis server. and accept client connections.

Start according to settings

Create three directories bin, etc, db under/usr/local/redis directory

Copy mkreleasehdr.sh, redis-benchmark, redis-check-rdb, redis-cli, redis-server from/usr/local/redis/src directory to bin directory

Under etc, create a new configuration redis.conf as follows.

Create a log file log-redis.log under/usr/local/redis and modify the permissions of the current user. sudo chown -R shoren /usr/local/redis/

Start server: redis-server /usr/local/redis/etc/redis.conf

Redis writes data to disk asynchronously by default. If not turned on, it may cause data loss for a period of time during power failure. Because redis itself synchronizes data files according to the above save conditions, so there are #data will only exist in memory for a period of time appendonly no#Specify the update log condition, there are 3 optional values: #no: indicates that the operating system synchronizes the data cache to disk (fast)#always: indicates that fsync() is manually called to write data to disk after each update operation (slow, safe)#everysec: indicates synchronization once per second (compromise, default) appendfsync everysec

Next, you can view the log as follows, indicating that the startup was successful:

Forcibly terminating the redis process may result in data loss because redis may be synchronizing memory data to the hard disk.

ps axu| grep redis ##Find PID kill -9 PID command for redis-server Close

Send the SHUTDOWN command to redis, redis-cli SHUTDOWN. After Redis receives the command, the server will disconnect all client connections, then perform persistence according to the configuration, and finally exit.

Start the client with the command redis-cli and connect to Redis (127.0.0.1: 6379) according to the default configuration.

Specify address and port number

Use the command redis-cli -h 127.0.0.1-p 6379

Turn off client interaction mode using quitAT8775:redis shoren$ redis-cli -h 127.0.0.1-p 6379##Simply use set, get command 127.0.0.1: 6379> set key value12OK127.0.1:6379> get key"value12"##Exit 127.0.0.1: 6379> quitAT8775:redis shoren$Above is "Example analysis of redis installation, setting, starting and stopping under mac" All the contents of this article, thank you for reading!
