生産環境はredis 4.0.11インストール全手順
まずinitializationを実行する.sh最適化スクリプトの詳細は、初期化スクリプトを参照してください.私たちのオンラインではredis-4.0.11を使用しています.tar.gzはログの内容によって最適化//後で処理を提出して、私達のここは先に実行することができて、分からない学友、引き続き後で見ることができます.
1：
[root@prd3-redis01-10-183 conf]# echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf
[root@prd3-redis01-10-183 conf]# sysctl -p
2：
[root@prd3-redis01-10-183 conf]# echo "net.core.somaxconn = 511" >> /etc/sysctl.conf
[root@prd3-redis01-10-183 conf]# sysctl -p

， ステップ1:最適化スクリプトinitializationを実行します.sh
ステップ2:redisのインストールパッケージをダウンロード[root@prd3-redis01-10-183 opt]# wget http://download.redis.io/releases/redis-4.0.11.tar.gz
ステップ3:必要な依存をダウンロードする:yum install-y tcl tcl-devel[root@prd3-redis 01-10-183 opt]#yum install-y tcl tcl-develヒント:インストール中にエラーメッセージが表示されます.解決策は、redisのインストール時にmake&&make installを実行するときにエラーメッセージが表示されることです[3]:gcc:Command not found/bin/sh:cc:command not found[root@mysql-redis-mgdb redis-4.0.11]#yum-y install gcc+gcc-c++解凍したredisパッケージを削除して再圧縮してからmake&&make installを再度実行
