Redis6安裝

Redis6安裝

Redis是c語言開發的，安裝redis需要c語言的編譯環境。

安裝redis6最主要的一點是要用GCC5以上，而CentOS7的GCC版本為4.8.x, 是以安裝之前必須更新GCC。

1.安裝新版本的gcc軟體包及依賴包

[root@TimeSync ~]# yum -y install centos-release-scl scl-utils-build

[root@TimeSync ~]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

#臨時啟用，退出shell後會恢複原系統gcc版本：

[root@TimeSync ~]# scl enable devtoolset-9 bash

#永久啟用：

[root@TimeSync ~]# echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile

2.設定系統參數

[root@TimeSync ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled

[root@TimeSync ~]# echo 511 > /proc/sys/net/core/somaxconn

[root@TimeSync ~]# echo vm.overcommit_memory=1 >> /etc/sysctl.conf

[root@TimeSync ~]# echo net.core.somaxconn= 1024 >> /etc/sysctl.conf

[root@TimeSync ~]# sysctl -p

[root@TimeSync ~]# ulimit -n 65535

3.檢視安裝後的gcc版本

[root@TimeSync ~]# scl enable devtoolset-9 bash

[root@TimeSync ~]# gcc --version

gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)

4.解壓redis安裝包

tar -zxvf redis-6.0.10.tar.gz -C /usr/local && mv redis-6.0.10 redis

cd redis

make && make test

make PREFIX=/usr/local/redis/ install

5.建立配置檔案目錄

mkdir -p /usr/local/redis/etc

指令安裝目錄：/usr/local/redis/bin

redis-benchmark: 性能測試工具，可以在自己本子運作，看看自己本子性能如何

redis-check-aof： 修複有問題的AOF檔案，rdb和aof後面講

redis-check-dump：修複有問題的dump.rdb檔案

redis-sentinel： Redis叢集使用

redis-server： Redis伺服器啟動指令

redis-cli： 用戶端使用操作入口

6.啟動redis

[root@TimeSync redis]# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

129524:C 19 Oct 2022 14:15:30.326 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

129524:C 19 Oct 2022 14:15:30.326 # Redis version=6.0.16, bits=64, commit=00000000, modified=0, pid=129524, just started

129524:M 19 Oct 2022 14:15:51.998 # Redis is now ready to exit, bye bye...

[root@TimeSync redis]#

7.檢視程序和端口

[root@TimeSync bin]# netstat -lantup |grep redis

tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 129534/redis-server

[root@TimeSync bin]# ps -ef |grep redis |grep -v grep

root 129534 53547 0 14:18 pts/1 00:00:00 redis-server 127.0.0.1:6379

[root@TimeSync bin]#
