1.获取redis资源
wget http://download.redis.io/releases/redis-4.0.8.tar.gz
2.解压
tar xzvf redis-4.0.8.tar.gz
3.安装
cd redis-4.0.8
make
cd src
make install PREFIX=/usr/local/redis
如果 make 编译失败，可执行以下命令安装 编译所需的环境
yum -y install gcc
yum -y install gcc-c++
再次执行 make 编译命令，如果报 error: jemalloc/jemalloc.h: No such file or directory等这种错误
zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h:55:2: error: #error “Newer version of jemalloc required”
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/data0/src/redis-2.6.2/src’
make: *** [all] Error 2
可查看 “Redis 安装报错 error: jemalloc/jemalloc.h: No such file or directory解决方法” 解决问题
4.移动配置文件到安装目录下
cd …/
mkdir /usr/local/redis/etc
mv redis.conf /usr/local/redis/etc
5.配置redis为后台启动
vi /usr/local/redis/etc/redis.conf //将daemonize no 改成daemonize yes
6.将redis加入到开机启动
vi /etc/rc.local //在里面添加内容：/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf (意思就是开机调用这段开启redis的命令)
7.开启redis
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
常用命令
redis-server /usr/local/redis/etc/redis.conf //启动redis
pkill redis //停止redis
卸载redis：
rm -rf /usr/local/redis //删除安装目录
rm -rf /usr/bin/redis-* //删除所有redis相关命令脚本
rm -rf /root/download/redis-4.0.4 //删除redis解压文件夹
扩展：
1、给redis设置登录密码
需要永久配置密码的话就去redis.conf的配置文件中找到requirepass这个参数，如下配置：
将 # requirepass foobared 注释打开
并修改为 requirepass xxx #指定密码xxx
保存后重启redis就可以了
2、远程连接失败问题：
同样修改redis.conf配置文件
#bind 127.0.0.1 修改为 bind 0.0.0.0
redis密码方式登录
./redis-cli -h 127.0.0.1 -p 6379 -a yourpassword
1.Redis服务端正在加载数据时，由于退出redis服务端或者关闭redis服务端窗口…，导致无法再次进入redis服务端，如下错误：
$ redis-server # 启动redis服务端
1051:C 06 May 2019 14:13:49.227 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1051:C 06 May 2019 14:13:49.227 # Redis version=5.0.4, bits=64, commit=00000000, modified=0, pid=1051, just started
1051:C 06 May 2019 14:13:49.227 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
1051:M 06 May 2019 14:13:49.228 * Increased maximum number of open files to 10032 (it was originally set to 256).
1051:M 06 May 2019 14:13:49.228 # Could not create server TCP listening socket *:6379: bind: Address already in use
(1)解决错误信息:
查看系统限制
$ ulimit -a
设置“open files”数量
$ ulimit -n 10032
2.再次进入redis服务端，如下错误：
$ redis-server
1061:C 06 May 2019 14:14:36.611 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1061:C 06 May 2019 14:14:36.611 # Redis version=5.0.4, bits=64, commit=00000000, modified=0, pid=1061, just started
1061:C 06 May 2019 14:14:36.611 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
1061:M 06 May 2019 14:14:36.613 # Could not create server TCP listening socket *:6379: bind: Address already in use
6379地址已经在使用（6379是redis默认的端口）
(2)解决错误信息：$ ps -ef | grep -i redis
进程号3272是redis的服务器
2.2、杀死该进程
使用"kill -9"命令
kill -9 3272 # 进程3272是redis服务器
2.3、重新启动redis服务器
$ redis-server
5377:C 05 May 2019 21:20:46.788 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
5377:C 05 May 2019 21:20:46.788 # Redis version=5.0.4, bits=64, commit=00000000, modified=0, pid=5377, just started
