Redis installation on centos7

CentOS7 On Redis install

1、redis Upload + compile + install

Download ahead of time redis-xxx.tar.gz The compressed file of , Then upload it locally redis Compress the file to the server . Drag and drop （ I'm using Xhell, Pay attention to the dragged directory , Upload to the directory where you drag it ） If appear ：

-bash: rz: Command not found , perform ：

yum -y install lrzsz

After uploading , Unzip the uploaded file

tar xzf redis-3.2.8.tar.gz   # -zxvf 

Decompression is obtained. redis-3.2.8 Folder , Get into redis-3.2.8 Folder , First, execute gcc -v, Check to see if there is gcc compiler , If you don't have to perform this step , Otherwise, skip ：

yum -y install gcc automake autoconf libtool make  # install gcc compiler 

compile redis The source file , Generate executable files ：

make MALLOC=libc  # Compile directly in the current directory , And generate the executable file to src Under the directory .

If you want to generate executable files into a pure directory , It can be executed ：

make install PREFIX=/usr/local/redis/redis  # Will be in redis The directory always generates one bin Folder , There are executable files  

Choose one of the two compilation methods .

So far, the compilation and installation are all completed , Has been able to put redis It's working . At this time, the default configuration file is used for startup .

notes ！ Can be in /usr/local/redis/redis Create three folders under the directory ：

mkdir data  # discharge redis Cached data 
mkdir conf # discharge redis Configuration file for 
mkdir logs  # discharge redis Log file of execution 

2、systemctl start-up redis+ Boot up redis

The installation is completed by decompressing redis after , If you want to Use systemctl start-up You need to write a script file to complete the startup process （ Automatic installation may not have this trouble ！）.

Use service To manage services , Need to be in /etc/init.d/ Create a script file in the directory .
Use systemctl similar ：

1. Get into /lib/systemd/system Directory scripting file rediss.service

cd /lib/systemd/system  # Enter the directory 
vi redis.service   # Create and edit 

redis.service The contents of the document are as follows ：

[Unit]  #[Unit]: It means that this is the basic West Sydney 
Description=Redis   #Description: describe 
After=network.target  #After: Indicates which application is launched after , Generally, it starts after the network service 

[Service]  #[Service]： Here is the service information 
ExecStart=/usr/local/redis/redis/bin/redis-server /usr/local/redis/redis/conf/redis.conf --daemonize no   #ExecStart： The command to start the service （ Path configure your actual installation path ）
#  If you need a password to connect to the client, configure ：
# ExecStop=/usr/local/redis/redis/bin/redis-cli -h 127.0.0.1 -p 6379 -a  password  shutdown
ExecStop=/usr/local/redis/redis/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown  #ExecStop： Order to stop service 

[Install]  #[Install]： Indicates the relevant Western Sydney installed 
WantedBy=multi-user.target  #WantedBy： How to start ：multi-user.target It shows that when the system is in multi-user mode （ Default run level ） Startup time , This service needs to be run automatically 

2. Create a soft connection

The purpose of creating a soft connection is , Automatically start the service preparation when the system is initialized .

Create a soft connection for the script file just created （ Be similar to windows Desktop shortcuts in the system ）.

#ls -s  Establish a soft connection 
#ls -s  source address   Destination address 
ls -s /lib/systemd/system/redis.service /etc/systemd/system/multi-user.target.wants/redis.service

3. Refresh configuration + start-up + stop it + restart

Just finished configuring systemctl After that, you need to refresh the configuration to take effect .

systemctl daemon-reload  # Refresh configuration 
systemctl start redis  # perhaps  systemctl start redis.service--> Turn on redis
ps -ef|grep redis  # After starting, you can check whether it has redis The process of 
systemctl stop redis  # perhaps  systemctl stop redis.service--> stop it redis
systemctl restart redis # perhaps  systemctl restart redis.service--> restart redis

4. redis Power on self start and disable

systemctl enable redis  # Boot from boot 
systemctl disable redis   # Disable power on auto start 
systemctl status redis  # View the current redis Start state of
