How to deploy Redis5.0.3 on CentOS7.6

1. Deployment steps

1. Installing gcc dependencies

Since redis is developed in C language, you must first confirm whether the gcc environment (gcc -v) is installed before installation. If it is not installed, execute the following command to install it.

# yum install -y gcc

2. Download and install

# wget http://download.redis.io/releases/redis-5.0.3.tar.gz
# tar -zxvf redis-5.0.3.tar.gz

3. Switch to the decompression directory and compile

# cd redis-5.0.3
# make

4． Install to the specified directory

# make install PREFIX=/usr/local/redis

5. Firewall settings

# firewall-cmd --zone=public --add-port=6379/tcp --permanent
# firewall-cmd --reload
# firewall-cmd --zone=public --query-port=6379/tcp

2. Start service

1． Front desk startup

# cd /usr/local/redis/bin/
# ./redis-server

2． Background startup

Copy redis.conf from the redis source code directory to the redis installation directory

# cp /home/ptcvi/redis-5.0.3/redis.conf /usr/local/redis/bin/
# vi redis.conf

Modify the redis.conf file and change daemonize no to daemonize yes

Add IP

Background startup

# ./redis-server redis.conf

3. Boot startup configuration

Add startup service

# vi /etc/systemd/system/redis.service

Copy and paste the following content:

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Note: ExecStart is configured to the installation path

Create redis command Soft link

# ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis

Set up startup

# systemctl daemon-reload
# systemctl enable redis.service
# systemctl start redis.service

4. Set password

Find the redis.windows.conf configuration in the redis root directory file, search for requirepass, find the comment password line, and add the password as follows:

# requirepass foobared
requirepass redis#123     //注意，行前不能有空格

Restart the service

#systemctl restart redis.service

5. Common commands for services

# systemctl start redis.service
停止redis服务
# systemctl stop redis.service 
重新启动服务
#systemctl restart redis.service
查看服务当前状态
# systemctl status redis.service
设置开机自启动
