centos7.8怎么安装redis5.0.10-创新互联
本篇内容主要讲解“centos7.8怎么安装redis5.0.10”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“centos7.8怎么安装redis5.0.10”吧!
准备
centos7.8服务器一台
修改主机名
# hostnamectl set-hostname redishost
安装redis
下载redis安装包
# cd /opt # wget https://download.redis.io/releases/redis-5.0.10.tar.gz
解压压缩包
# cd /opt # tar -zxf redis-5.0.10.tar.gz
编译安装
# cd /opt # cd redis-5.0.10 ## 安装gcc编译器 # yum install gcc # make MALLOC=libc # # make install cd src && make install make[1]: Entering directory `/opt/redis-5.0.10/src' Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install make[1]: Leaving directory `/opt/redis-5.0.10/src
修改系统参数
## 修改sysctl.conf # ( cat <> /etc/sysctl.conf
以上操作是解决redis-server默认启动提示的前两个警告的持久方案，附redis-server默认启动的两个警告信息如下：
The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
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.
修改系统启动参数关闭TCP
## 修改/etc/default/grub ## 在指定行加 transparent_hugepage=never # vi /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet transparent_hugepage=never" GRUB_DISABLE_RECOVERY="true" ## 重新生成grub配置文件 # grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-1127.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-1127.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-385c7efe9475460c95c436866e593af3 Found initrd image: /boot/initramfs-0-rescue-385c7efe9475460c95c436866e593af3.img done
以上操作是解决redis-server默认启动提示的第三个警告的持久方案，附redis-server默认启动的第三个警告信息如下：
you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix thisissue 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 thesetting after a reboot. Redis must be restarted after THP is disabled.
根据提示将’echo never > /sys/kernel/mm/transparent_hugepage/enabled’ 写入/etc/rc.local 其实并没有用，换成修改grub启动文件可以生效。
以后台进程方式启动redis
修改配置文件redis.conf
# cd /opt/redis-5.0.10 # mkdir /etc/redis # cp redis.conf /etc/redis/redis.conf
在/etc/redis/redis.conf中修改以下3项
以后台进程方式启动
修改daemonize no 为daemonize yes
设置redis远程连接
注释掉bind 127.0.0.1
设置redis连接密码
在requirepass foobard改为requirepass redis1234
设置systemctl启动程序
/usr/lib/systemd/system/redis.service
[Unit] Description=Redis 6379 After=syslog.target network.target [Service] Type=forking PrivateTmp=yes Restart=always ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf User=root Group=root LimitCORE=infinity LimitNOFILE=100000 LimitNPROC=100000 [Install] WantedBy=multi-user.target
配置自动启动
systemctl daemon-reload systemctl enable redis
启动命令
systemctl enable redis systemctl start redis systemctl restart redis
{{o.name}}
{{m.name}}
