This article is about how to install redis-3.0.5 from source code. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

# install redis-server #

# create and run users

Useradd redis-s / sbin/nologin-M

# upload the software to the specified location, and the location where my software is saved is

Mkdir-p / server/tools/

# decompress, configure, compile, install

Cd / server/tools/tar-zxf redis-3.0.5.tar.gz cd redis-3.0.5make PREFIX=/usr/local/redismake PREFIX=/usr/local/redis install

# configure redis environment variables

Echo'> > / etc/profileecho'> PATH for redis-server' > > / etc/profileecho 'export PATH=/usr/local/redis/bin/:$PATH' > > / etc/profile tail-3 / etc/profilesource / etc/profileecho $PATH

# or (restart fails)

Export PATH=/usr/local/redis/bin/:$PATHecho $PATH

# create configuration files, data, logs and other related directories, and copy configuration files

# creating a standard directory structure helps to form good habits and improve efficiency

Mkdir-p / usr/local/redis/confmkdir-p / usr/local/redis/datamkdir-p / usr/local/redis/logscp redis.conf / usr/local/redis/conf/cd / usr/local/redis/conf/tree / usr/local/redis

# at this point, the basic configuration of redis has been completed, and you can start using the initial configuration of redis

# start command

/ usr/local/redis/bin/redis-server / usr/local/redis/conf/redis.conf &

# View startup status, process and port

Ps-ef | grep redisnetstat-anptl | grep redis

# testing and use

# client connection command is:

/ usr/local/redis/bin/redis-cli-p 6379 [root@cache redis] # redis-cli-p 6379127.0.0.1 redis-cli 6379 > set a 1OK127.0.0.1:6379 > get a "1" 127.0.0.1 keys 6379 > set b 2OK127.0.0.1:6379 > set c 3OK127.0.0.1:6379 > keys * 1) "c" 2) "a" 3) "b" 127.0.0.1v 6379 > exit

# above are simple tests to verify whether the installation is correct or not

# safely disable redis

/ usr/local/redis/bin/redis-cli shutdown

# when redis is closed, the data will be saved as dump.rdb by default in the location where redis was started.

# when starting redis-server with default configuration, the following warning message appears: it does not affect the use of

# however, it is my custom that I will not tolerate the existence of such warnings:

# look for the following keywords in the configuration file, and you can modify them as follows:

The above is a simple optimized configuration of redis
