How to install Redis in Centos7

1 Preliminary preparation

1.1 Download the redis installation package

You can also download other versions, I download the 5.0.8 version here.

1.2 Upload the installation package

Upload the downloaded installation package to the specified directory on the server, and then decompress it through tar -zxvf xxxx, such as:

Second check gcc

Installing redis requires a c environment, so offline installation requires downloading some dependent installation packages.

2.1 Download address: https://vault.centos.org/7.0.1406/os/x86_64/Packages/

cpp-4.8.2-16.el7.x86_64.rpm
gcc-4.8.2-16.el7.x86_64.rpm
glibc-2.17-55.el7.x86_64.rpm
glibc-common-2.17-55.el7.x86_64.rpm
glibc-devel-2.17-55.el7.x86_64.rpm
glibc-headers-2.17-55.el7.x86_64.rpm
glibc-static-2.17-55.el7.x86_64.rpm
glibc-utils-2.17-55.el7.x86_64.rpm
kernel-headers-3.10.0-123.el7.x86_64.rpm
libmpc-1.0.1-3.el7.x86_64.rpm
mpfr-3.1.1-4.el7.x86_64.rpm

Choose to download the above to meet the installation needs.

2.2 After the download is completed, upload it to the server and install it through rpm

rpm -Uvh *.rpm --nodeps --force

--nodeps When installing the package, the dependencies are not checked. For example, when installing B, B depends on C and cannot be installed. Use -- nodeps can be installed successfully

--force force installation

2.3 Check whether the installation is successful

rpm -q gcc

Three installation Redis

cd redis-5.0.8 Enter the decompressed directory

3.1 Compile redis

make

3.2 Install the compiled files to the directory

make PREFIX=/usr/local/redis install

Note: PREFIX is required At the same time, the redis directory will be automatically created for us, and the result will be installed in this directory

3.3 After the installation is completed, the following files will be generated in the /usr/local/bin/ folder

3.4 Configure redis.conf

cd Go to the installation package decompression directory and copy redis.conf to the directory where redis is installed

cd redis-5.0.8

mkdir /usr/local/redis/etc

cp redis.conf /usr/local/redis/etc

vim redis.conf

daemonize no is changed to daemonize yes

requirepass is changed to redis123 (This is a redis add password)

appendonly yes Comment open

3.5 Open service port

# 查看6379端口是否开启
firewall-cmd --query-port=6379/tcp

# 开启6379端口
firewall-cmd --permanent --add-port=6379/tcp

3.6 Redis startup

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

3.7 View process

ps -ef|grep redis

3.8 Client startup

# 没密码
./redis-cli 

# 有密码
./redis-cli -a redis123

3.9 Execute command on the server

redis-cli -h host -p port -a password

格式为 redis-cli –h IP地址 –p 端口 –a 密码

3.10 Redis shutdown

First way

# 查询进度PID   
ps -ef | grep -i redis
# 关闭
kill -9 PID

Second Method

./bin/redis-cli shutdown

Four uninstall

4.1 First close the redis service
4.2 Then delete the redis-related files in the /usr/local/redis/bin/ directory

rm -rf /usr/local/redis/bin/redis*
