The specific installation steps are as follows:
1. Install redis
The first step: Download the redis installation package
[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz --2017-12-13 12:35:12-- http://download.redis.io/releases/redis-4.0.6.tar.gz Resolving download.redis.io (download.redis.io)... 109.74.203.151 Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1723533 (1.6M) [application/x-gzip] Saving to: ‘redis-4.0.6.tar.gz’ 100%[==========================================================================================================>] 1,723,533 608KB/s in 2.8s 2017-12-13 12:35:15 (608 KB/s) - ‘redis-4.0.6.tar.gz’ saved [1723533/1723533]
Second Step: Unzip the compressed package
tar -zxvf redis-4.0.6.tar.gz [root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
Step three: yum installs gcc dependencies
yum install gcc [root@iZwz991stxdwj560bfmadtZ local]# yum install gcc
When you encounter a choice, enter y
Step four: Jump to redis to decompress Directory
cd redis-4.0.6 [root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
Step 5: Compile and install
make MALLOC=libc [root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc
Add the files in the /usr/local/redis-4.0.6/src directory to the /usr/local/bin directory
cd src && make install
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)

INSTALL install2. Three ways to start redis
First switch to the redis src directory
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
1. Start redis directly
./redis-server
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server

18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
18685:M 13 Dec 12:56:12.508 * Ready to accept connectionsAs shown above: redis starts successfully, but this startup method requires the window to be opened all the time, and other operations cannot be performed, which is not convenient.
Press ctrl c to close the window.
2. Start redis as a background process
The first step: modify the redis.conf file
will
daemonize no
Modify to
daemonize yes
Step 2: Specify the redis.conf file to start
./redis-server /usr/local/redis-4.0.6/redis.conf [root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf 18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started18713:C 13 Dec 13:07:41.109 # Configuration loaded
Step 3: Close the redis process
First use ps - aux | grep redis to view the redis process
[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
Use the kill command to kill the process
[root@iZwz991stxdwj560bfmadtZ src]# kill 18714
3. Set redis to start automatically after booting
1. Create a new redis directory in the /etc directory
mkdir redis [root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
2. Copy the /usr/local/redis-4.0.6/redis.conf file to the /etc/redis directory and name it 6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
3 , Copy the redis startup script and put it in the /etc/init.d directory
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
4. Set redis to start automatically after booting
First switch to the /etc/init.d directory
Then execute the self-start command
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on service redisd does not support chkconfig
The result is that redisd does not support chkconfig
Solution:
Use vim to edit the redisd file, in the first line Add the following two lines of comments, save and exit
# chkconfig: 2345 90 10# description: Redis is a persistent key-value database
The comment means that the redis service must be started or shut down in run levels 2, 3, 4, and 5. The startup priority is 90 and the shutdown priority is Yes 10
Execute the boot auto-start command again, success
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
Now you can start and shut down redis directly as a service
Startup:
service redisd start [root@izwz991stxdwj560bfmadtz ~]# service redisd startStarting Redis server...2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started2288:C 13 Dec 13:51:38.087 # Configuration loaded
Shutdown:
Method 1: service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop Stopping ... Redis stopped
Method 2: redis-cli SHUTDOWN
