Centos7离线安装redis

1.1 下载、上传、解压redis4.0.11

下载地址：http://download.redis.io/releases/redis-4.0.11.tar.gz
下载后上传到服务器上，并解压：
备注：这里是上传压缩包到/opt/redis目录下。

[root@CDH-143 redis]# tar -zxvf redis-4.0.11.tar.gz
redis-4.0.11/
redis-4.0.11/.gitignore
......
redis-4.0.11/utils/whatisdoing.sh
[root@CDH-143 redis]# ls
redis-4.0.11 redis-4.0.11.tar.gz
[root@CDH-143 redis]# cd redis-4.0.11/
[root@CDH-143 redis-4.0.11]# ls
00-RELEASENOTES CONTRIBUTING deps Makefile README.md runtest runtest-sentinel src utils
BUGS COPYING INSTALL MANIFESTO redis.conf runtest-cluster sentinel.conf tests

1.2 安装gcc

1）如果执行gcc –version出现以下信息，表示已经安装过gcc，可以跳过该步骤：

[boco@CDH-143 spark_job_monitor]$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
[root@CDH-143 redis]# 

2）否则，如果执行make命令报下面错误，说明系统上没有安装C语言环境，需要安装，在linux系统上的C环境是gcc，因此需要安装gcc。

make[3]: gcc: Command not found
make[3]: *** [net.o] Error 127
make[3]: Leaving directory `/home/work/redis/deps/hiredis'
make[2]: *** [hiredis] Error 2
make[2]: Leaving directory `/home/work/redis/deps'
make[1]: [persist-settings] Error 2 (ignored)
CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory `/home/work/redis/src'
make: *** [all] Error 2

安装gcc，

方式1：从centos7的系统安装镜像中提取：解压镜像文件，进入"Packages"目录，取出如下图所示rpm包

方式2：访问镜像网站获取：http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/ ，然后将其上传

从里面packages找出来，这些是从网上整理出来的（15个文件不要漏掉！！）

解压gcc.zip，编译安装

[root@CDH-143 soft]# unzip gcc.zip
[root@CDH-143 soft]# cd gcc
[root@CDH-143 soft]# rpm -Uvh *.rpm --nodeps --force

查看gcc版本，出现以下信息，表示安装成功

[boco@CDH-143 spark_job_monitor]$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)
Copyright (C) 2015 Free Software Foundation, Inc.

[root@CDH-143 redis]#

1.3 编译安装redis

[root@CDH-143 redis-4.0.11]# make MALLOC=libc
cd src && make all
。。。。。。。。
CC rax.o
LINK redis-server
INSTALL redis-sentinel
CC redis-cli.o
LINK redis-cli
CC redis-benchmark.o
LINK redis-benchmark
INSTALL redis-check-rdb
INSTALL redis-check-aof
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/opt/redis/redis-4.0.11/src'
[root@CDH-143 redis-4.0.11]#
[root@CDH-143 redis-4.0.11]# cd src && make install
CC Makefile.dep

Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install

编译安装成功。

1.4 启动redis

[root@CDH-143 src]# ./redis-server
24496:C 11 Mar 13:49:56.298 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

This will create latency and memory usage issues with Redis. To fix this issue 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 the setting after a reboot. Redis must be restarted after THP is disabled. 24496:M 11 Mar 13:49:56.303 * Ready to accept connections

启动成功。
以下为设置redis开机自启，并且添加到系统服务

1.4.1 复制redis配置文件

[root@CDH-143 src]# mkdir /etc/redis
[root@CDH-143 src]# cd ..
[root@CDH-143 redis-4.0.11]# ls
00-RELEASENOTES CONTRIBUTING deps Makefile README.md runtest runtest-sentinel src utils
BUGS COPYING INSTALL MANIFESTO redis.conf runtest-cluster sentinel.conf tests
[root@CDH-143 redis-4.0.11]# cp redis.conf /etc/redis/6379.conf

修改redis启动为后台启动：

[root@CDH-143 redis-4.0.11]# vi /etc/redis/6379.conf

1.4.2 将启动文件拷贝到init.d中

[root@CDH-143 redis-4.0.11]# cp utils/redis_init_script /etc/init.d/redisd

1.4.3 修改启动脚本参数

[root@CDH-143 redis-4.0.11]# vi /etc/init.d/redisd

添加以下代码，:wq保存退出

添加

# chkconfig: 2345 10 90
# description: Start and Stop redisd

修改：

EXEC=/opt/redis/redis-4.0.11/src/redis-server
CLIEXEC=/opt/redis/redis-4.0.11/src/redis-cli
PIDFILE=/opt/redis/redis-4.0.11/redis_${REDISPORT}.pid

1.4.4 增加脚本执行权限

[root@CDH-143 redis-4.0.11]# chmod +x /etc/init.d/redisd

1.4.5 增加系统服务

[root@CDH-143 redis-4.0.11]# chkconfig --add redisd
[root@CDH-143 redis-4.0.11]# chkconfig --list redisd

Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.

If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.

redisd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@CDH-143 redis-4.0.11]#

1.4.6 启动redis服务测试

[root@CDH-143 redis-4.0.11]# service redisd start
Starting Redis server...
9084:C 11 Mar 15:23:36.469 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

9084:C 11 Mar 15:23:36.469 # Configuration loaded
[root@CDH-143 redis-4.0.11]#
[root@CDH-143 redis-4.0.11]# ps -aux | grep redis

root 8870 0.0 0.0 112660 956 pts/2 S+ 15:22 0:00 grep --color=auto redis

配置完毕，重启服务器，测试是否成功
