這篇文章主要介紹了關(guān)于linux redis安裝及安裝遇到的問題,本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

Linux安裝Redis服務(wù)步驟：

獲取資源指定安裝目錄

[root@hadoop-master mnt]# mkdir reids
 
[root@hadoop-master redis]# cd redis
 
[root@hadoop-master redis]# wget http://download.redis.io/releases/redis-6.0.5.tar.gz
 
[root@hadoop-master redis# tar xzf redis-6.0.5.tar.gz
 
[root@hadoop-master redis]# cd redis-6.0.5
 
[root@hadoop-master redis-6.0.5]# make install PREFIX=/mnt/redis

可能會因?yàn)榉?wù)器中g(shù)cc版本的問題報(bào)錯(cuò)，如遇到報(bào)錯(cuò)就更新

make[1]: *** [server.o] 錯(cuò)誤 1
make[1]: 離開目錄“/usr/redis-6.0.1/src”
make: *** [all] 錯(cuò)誤 2
server.c:2402:11: 錯(cuò)誤：‘struct redisServer'沒有名為‘a(chǎn)ssert_file'的成員
   server.assert_file = "<no file>";
      ^
server.c:2403:11: 錯(cuò)誤：‘struct redisServer'沒有名為‘a(chǎn)ssert_line'的成員
   server.assert_line = 0;
      ^
server.c:2404:11: 錯(cuò)誤：‘struct redisServer'沒有名為‘bug_report_start'的成員
   server.bug_report_start = 0;
      ^
server.c:2405:11: 錯(cuò)誤：‘struct redisServer'沒有名為‘watchdog_period'的成員
   server.watchdog_period = 0;
      ^
server.c:2411:11: 錯(cuò)誤：‘struct redisServer'沒有名為‘lua_always_replicate_commands'的成員
   server.lua_always_replicate_commands = 1;

解決方案

[root@hadoop-master redis-6.0.5]# gcc -v               # 查看gcc版本
[root@hadoop-master redis-6.0.5]# yum -y install centos-release-scl # 升級到9.1版本
[root@hadoop-master redis-6.0.5]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[root@hadoop-master redis-6.0.5]# scl enable devtoolset-9 bash
以上為臨時(shí)啟用，如果要長期使用gcc 9.1的話：
[root@hadoop-master redis-6.0.5]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

再次執(zhí)行

#指定安裝的位置
[root@hadoop-master redis-6.0.5]# make install PREFIX=/mnt/redis

成功提示

執(zhí)行make test出錯(cuò)解決方案

[root@localhost redis-6.0.5]# yum install tcl
[root@localhost redis-6.0.5]# make test

啟動redis

[root@hadoop-master redis]# cd /mnt/redis/bin/
 
#指定配置文件
[root@hadoop-master bin]# ./redis-server ../redis-6.0.5/redis.conf
