前置环境
apt-get update apt install make apt install gcc gcc+ build-essential tcl
下载安装
cd /app wget http://download.redis.io/releases/redis-5.0.5.tar.gz tar zxvf redis-5.0.5.tar.gz cd redis-5.0.5 make MALLOC=libc make test cd src && make install PREFIX=/usr/local/redis # 安装成功后 root@redis-node1:/app/redis-5.0.5/src# make install PREFIX=/usr/local/redis Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install
make test出错
!!! WARNING The following tests failed:
*** [err]: PEXPIRE/PSETEX/PEXPIREAT can set sub-second expires in tests/unit/expire.tcl
Expected 'somevalue {}' to equal or match '{} {}'
Cleanup: may take some time... OK
Makefile:262: recipe for target 'test' failed
make[1]: *** [test] Error 1
make[1]: Leaving directory '/app/redis-5.0.5/src'
Makefile:6: recipe for target 'test' failed
make: *** [test] Error 2
某些操作性需要更多的时间，修改tests/unit/expire.tcl
tags {"slow"} {
test {EXPIRE - After 2.1 seconds the key should no longer be here} {
after 21000 # 这里加个0
list [r get x] [r exists x]
} {{} 0}
}
test {EXPIRE - write on expire should work} {
r del x
r lpush x foo
r expire x 10000 # 这里加个0
r lpush x bar
r lrange x 0 -1
} {bar foo}
# 如下输出安装成功
\o/ All tests passed without errors!
Cleanup: may take some time... OK

启动
/usr/local/bin/redis-server /usr/local/redis/conf/6379 --daemonize no # 启动后会报如下警告 3195:M 15 Sep 2019 22:17:50.852 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128. 3195:M 15 Sep 2019 22:17:50.852 # Server initialized 3195:M 15 Sep 2019 22:17:50.852 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect. 3195:M 15 Sep 2019 22:17:50.852 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled. 3195:M 15 Sep 2019 22:17:50.852 * Ready to accept connections #安装提示解决即可 # 解决第一个，第二个 vim /etc/sysctl.conf 添加 net.core.somaxconn = 1024 vm.overcommit_memory = 1 # 生效 sysctl -p # 解决第三个 # shell执行，重启会失效 echo never > /sys/kernel/mm/transparent_hugepage/enabled # 永久生效 vim /etc/rc.local 添加 echo never > /sys/kernel/mm/transparent_hugepage/enabled
加入systemctl
vim /etc/systemd/system/redis.service systemctl daemon-reload systemctl enable redis.service systemctl start redis # 内容如下 root@redis-node1:/data/redis# cat /etc/systemd/system/redis.service [Unit] Description=Redis In-Memory Data Store After=network.target [Service] User=root Group=root ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/conf/6379 --daemonize no ExecStop=/usr/local/redis/bin/redis-cli -h 10.13.6.21 -p 6379 shutdown Restart=always [Install] WantedBy=multi-user.target

主从模式 - slave安装方式同上，配置文件略有不同
