# hostnamectl set-hostname redishost
# cd /opt # wget https://download.redis.io/releases/redis-5.0.10.tar.gz
# cd /opt # tar -zxf redis-5.0.10.tar.gz
# cd /opt # cd redis-5.0.10 ## 安裝gcc編譯器 # 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sysctl.conf # ( cat <> /etc/sysctl.conf
以上操作是解決redis-server默認啟動提示的前兩個警告的持久方案,附redis-server默認啟動的兩個警告信息如下:
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/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
以上操作是解決redis-server默認啟動提示的第三個警告的持久方案,附redis-server默認啟動的第三個警告信息如下:
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.
根據(jù)提示將’echo never > /sys/kernel/mm/transparent_hugepage/enabled’ 寫入/etc/rc.local 其實并沒有用,換成修改grub啟動文件可以生效。
# 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項
以后臺進程方式啟動
修改daemonize no 為daemonize yes
設置redis遠程連接
注釋掉bind 127.0.0.1
設置redis連接密碼
在requirepass foobard改為requirepass redis1234
