Installing Redis 6.2.4 on Linux with GCC 9 and Systemd Service

Click the blue “DevOps Architecture Practice” to follow me.

Share to “Moments”, and every morning at 08:06 I push practical content!

GCC needs to be upgraded to version 9.0 or higher.

gcc --version

gcc (GCC) 9.3.0

-rw-r--r-- 1 root root 2457940 Jun 15 16:03 redis-6.2.4.tar.gz

make -j2 && make install

The same version is already installed, so compilation is not needed; just copy the files to the target directories.

ll /usr/local/bin/redis-*

redis-server --version

Redis server v=6.2.4 sha=00000000:0 malloc=jemalloc-5.1.0 bits=64 build=b60f19d9346e4f3b

mkdir -p /usr/local/redis

mkdir -p /data/redis

cd src/

cp ./redis-server /usr/local/redis/

cp ./redis-cli /usr/local/redis/

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

Show the systemd unit file for redis-server:

[Unit]

Description=The redis-server Process Manager

After=syslog.target network.target

[Service]

Type=simple

PIDFile=/data/redis/redis.pid

ExecStart=/usr/local/redis/redis-server /usr/local/redis/redis.conf

ExecReload=/bin/kill -USR2 $MAINPID

ExecStop=/bin/kill -SIGINT $MAINPID

[Install]

WantedBy=multi-user.target

systemctl daemon-reload

systemctl start redis-server

Verify installed files:

-rw-r--r-- 1 root root 5909 Jun 15 17:38 redis.log

-rw-r--r-- 1 root root 6 Jun 15 17:38 redis.pid

Check Redis configuration:

redis

127.0.0.1:6379> CONFIG GET maxclients

1) "maxclients"

2) "10000"

Performance tuning suggestions:

1. Adjust the system's maximum number of connections.

2. Optimize memory settings.

3. Compress data before storing it in Redis.

4. Deploy multiple clusters for distributed scaling.
