1. Install gcc-c++, tcl

yum install gcc-c++ tcl

2. Decompress, compile and test

tar zxvf redis-5.0.5.tar.gz
make
make test

3. Install to / opt

make PREFIX=/opt/redis/redis-5.0.5 install
# Create a soft chain
ln -s redis-5.0.5 latest

4. Configuration file. There is an example redis.conf in the source file directory. The final configuration content is (the second half uses default, no change).

[root@p01 ~]# cat /opt/redis/latest/conf/redis_16379.conf | grep -v '^$'|grep -v '^#'|grep -v '^;'
bind 192.168.123.32
protected-mode yes
port 16379
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
supervised auto
pidfile /var/run/redis_16379.pid
loglevel notice
logfile "/data/redis/logs/redis_16379.log"
databases 16
always-show-logo yes
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
dir /data/redis/db/
replica-serve-stale-data yes
replica-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-disable-tcp-nodelay no
replica-priority 100
requirepass rzczurzlx4xzs|yjpkdjzhljlevY0bLh
....

5. When daemonize is set to no, directly start the test with the command line and observe the log output.

./bin/redis-server ./conf/redis_16379.conf

6. Solve warning

For / proc/sys/net/core/somaxconn and overcommit \ memory is set to 0, modify / etc/sysctl.conf and add

net.core.somaxconn = 1024
vm.overcommit_memory = 1

Then execute sysctl -p

For the transparent page, first modify it in real time

echo never >> /sys/kernel/mm/transparent_hugepage/enabled
echo never >> /sys/kernel/mm/transparent_hugepage/defrag

inspect

[root@middle ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
[root@middle ~]# cat /sys/kernel/mm/transparent_hugepage/defrag
[always] madvise never
# All the above needs to be changed into never

Join to start automatic modification

# Add the following to / etc/rc.local

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi

if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

.

7. Join Systemd service. Add / lib/systemd/system.redis.service, as follows

[root@p01 ~]# more /lib/systemd/system/redis.service 
[Unit]
Description=Redis
After=network.target

[Service]
Type=forking
PIDFile=/var/run/redis_16379.pid
ExecStart=/opt/redis/latest/bin/redis-server /opt/redis/latest/conf/redis_16379.
conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Join service and start

systemctl enable redis.service
systemctl start redis
systemctl status redis

.
