Install redis5.0 in CentOS7

1. Environment Introduction##

• CentOS7 (Development Tools not installed)

2. Download Redis5.0-rc3

wget -O redis-5.0-rc3.tar.gz https://github.com/antirez/redis/archive/5.0-rc3.tar.gz

3. Unzip redis

tar -zxvf redis-5.0-rc3.tar.gz -C /usr/local

4. Compile and install##

cd /usr/local/redis-5.0-rc3
make

There will be an error:

compilation terminated.
make[1]:***[adlist.o] Error 1
make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src'
make:***[all] Error 2

Install Development Tools

yum groupinstall 'Development Tools'

If executed again, an error will be reported

make
cd src && make all
make[1]: Entering directory `/usr/local/redis-5.0-rc3/src'
 CC adlist.o
In file included from adlist.c:34:0:
zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory
 # include <jemalloc/jemalloc.h>
                               ^
compilation terminated.
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src'
make:***[all] Error 2

The final solution is as follows:

cd /usr/local/redis-5.0-rc3/deps; make hiredis lua jemalloc linenoise

After the compilation is complete, execute the make command again in /usr/local/redis-5.0-rc3

cd /usr/local/redis-5.0-rc3
make

The compilation is successful when the following appears

Hint: It's a good idea to run 'make test' ?

make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src'

Then execute the installation command in /usr/local/redis-5.0-rc3/src:

cd /usr/local/redis-5.0-rc3/src
make install

The following log information will appear

 INSTALL install

 INSTALL install

5. Modify the redis.conf configuration file##

vim /usr/local/redis-5.0-rc3/redis.conf

Just need to adjust the following

protected-mode no #Turn off protection mode
daemonize yes     #Daemon mode is on

6. Start redis5.0

/usr/local/redis-5.0-rc3/src/redis-server /usr/local/redis-5.0-rc3/redis.conf

In fact, when we execute make install, we will copy several commands under src to /usr/local/bin/, or execute the following command to start redis5.0

/usr/local/bin/redis-server /usr/local/redis-5.0-rc3/redis.conf

Check port

netstat -ltnp |grep 6379

If there is port monitoring, redis has been started successfully.

Try to connect

redis-cli

Why can the redis-cli command be executed in any directory, because the redis-cli command is in the /usr/local/bin directory, and the directory is configured in the PATH, so you can execute ls, mkdir Wait for commands to execute commands such as redis-cli or redis-server.

Generally, we will delete the installation package after installing redis. Then we only need to move the redis.conf configuration file to other directories, such as: /etc/redis/redis.conf, where is the specific location? Just place it according to your own habits or specifications.
