Centos7 offline mode installation Redis6.2.13 detailed steps (rpm mode)

This article mainly introduces the installation of Redis6.2.13 in the CentOS7 server. The premise is that there is a gcc environment, so here I will also introduce the detailed installation process of gcc. I refer to many other related blogs, but some bloggers’ articles It may be transported, which caused me to report an error during the actual operation, so I will also introduce the troubleshooting solution here.

3. Unzip the Redis compressed package and install the configuration

Redis download address: https://redis.io/download/#redis-downloads

3.1 Unzip the file

#进入到文件目录 路径是自己情况修改
cd /usr/local/redis
# 解压
tar -xvf redis-6.2.13.tar.gz -C /usr/local/redis

3.2 Compile and install files

# 进入到解压后的文件目录 路径是自己情况修改
cd /usr/local/redis/redis-6.2.13
# 编译
make
# 指定安装目录并进行安装
make install PREFIX=/usr/local/redis

If makean error occurs when using the command: zmalloc.h:50:31: Fatal error: jemalloc/jemalloc.h: There is no such file or directory, you
can use make MALLOC=libcthe command.
For details, see: Redis installation error: zmalloc.h:50:31: Fatal error: jemalloc/jemalloc.h: No such file or directory

After using the make command to compile, if the screenshot frame selection appears at the end of the command line output, the compilation is successful.

Specify the installation directory and perform the installation. If the following content appears, the installation is successful.

3.3 Modify the configuration file

# 复制配置文件到bin目录  目录需要自己视情况修改 复制语法：cp <源文件> <目标文件夹路径> 
cp /usr/local/redis/redis-6.2.13/redis.conf /usr/local/redis/bin
# 进入redis安装目录
cd /usr/local/redis/bin/
# 修改配置文件
vim redis.conf

If you want to set the specified IP to connect to redis, you only need to modify the bind configuration item in the redis.conf file. If the IP is not limited, change 127.0.0.1 to 0.0.0.0, or comment this line.

Modify the port number

and set it to start automatically when booting.

Disable the protection mode.

3.4 Start the service

# 启动服务
./redis-server redis.conf
# 查看进程
ps -ef |grep redis

# ExecStart需要按照实际情况修改成自己的地址
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

3.5 Start the service

# 开机自动启动
