下载redis的稳定版本
根据上面的页面，获取下载链接，进行下载。
wget http://download.redis.io/releases/redis-stable.tar.gz

解压redis安装包
[root@server01 ~]# tar -zxvf redis-stable.tar.gz
image
image
yum安装gcc依赖
[root@server01 ~]# yum install gcc -y
image
编译安装
[root@server01 ~]# cd redis-stable
[root@server01 redis-stable]# 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@server01 redis-stable]# make MALLOC=libc

生成了src目录文件之后，进入src（源文件目录）继续编译，如下：
[root@server01 src]# make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install

[root@server01 src]#

测试是否安装成功
[root@server01 src]# pwd
/root/redis-stable/src
[root@server01 src]# ./redis-server
image

配置redis
以后台进程方式启动：
1.修改/root/redis-stable/redis.conf： daemonize no 将值改为yes 保存退出
[root@server01 redis-stable]# pwd
/root/redis-stable
[root@server01 redis-stable]# vim redis.conf
image
将daemonize no 改为 yes
image
image
指定redis.conf文件启动
[root@server01 src]# ./redis-server /root/redis-stable/redis.conf
1335:C 05 Dec 2018 08:49:43.682 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1335:C 05 Dec 2018 08:49:43.682 # Redis version=5.0.2, bits=64, commit=00000000, modified=0, pid=1335, just started
1335:C 05 Dec 2018 08:49:43.682 # Configuration loaded
[root@server01 src]#
image
这时候redis服务已经后台运行了，下一步就需要配置使用密码认证以及远程访问的配置。
[root@server01 src]# ps -ef | grep redis
root 1336 1 0 08:49 ? 00:00:00 ./redis-server 127.0.0.1:6379
root 1371 1313 0 09:00 pts/0 00:00:00 grep --color=auto redis
[root@server01 src]#
设置redis远程连接
关闭selinux 以及 firewalld 或者 放行 6379 默认端口
[root@server01 selinux]# service firewalld stop
[root@server01 selinux]# systemctl disable firewalld
配置redis.conf中将bind 127.0.0.1 改为bind 0.0.0.0或者注释该行
image
设置redis连接密码
在
redis.conf中搜索requirepass这一行，然后在合适的位置添加配置
image
更新
redis配置
再次执行启动加载配置的命令即可。
[root@server01 src]# ./redis-server /root/redis-stable/redis.conf
1182:C 05 Dec 2018 09:09:58.721 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1182:C 05 Dec 2018 09:09:58.721 # Redis version=5.0.2, bits=64, commit=00000000, modified=0, pid=1182, just started
1182:C 05 Dec 2018 09:09:58.721 # Configuration loaded
[root@server01 src]#
[root@server01 src]# ps -ef | grep redis
root 1177 1 0 09:09 ? 00:00:00 ./redis-server 0.0.0.0:6379
root 1185 1147 0 09:11 pts/0 00:00:00 grep --color=auto redis
[root@server01 src]#
设置开机自启动
关闭redis服务
[root@server01 src]# ps -ef | grep redis
root 1177 1 0 09:09 ? 00:00:00 ./redis-server 0.0.0.0:6379
root 1185 1147 0 09:11 pts/0 00:00:00 grep --color=auto redis
[root@server01 src]#
[root@server01 src]# ps -aux | grep redis
root 1177 0.0 0.2 144008 2028 ? Ssl 09:09 0:00 ./redis-server 0.0.0.0:6379
root 1187 0.0 0.0 112708 976 pts/0 R+ 09:11 0:00 grep --color=auto redis
[root@server01 src]#
[root@server01 src]# kill -9 1177
[root@server01 src]#
[root@server01 src]# ps -aux | grep redis
root 1189 0.0 0.0 112708 980 pts/0 R+ 09:12 0:00 grep --color=auto redis
[root@server01 src]#

查看
redis-stable/utils目录下的启动脚本
image
image
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"
查看
/usr/local/bin目录是否存在redis执行文件
image
那么剩下就是需要设置配置文件了。
在/etc目录下新建redis目录
[root@server01 utils]# mkdir -p /etc/redis
[root@server01 utils]#
[root@server01 utils]# ls /etc/redis/
[root@server01 utils]#
将/redis-stable/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf
[root@server01 redis-stable]# pwd
/root/redis-stable
[root@server01 redis-stable]#
[root@server01 redis-stable]# cp redis.conf /etc/redis/6379.conf
[root@server01 redis-stable]#
[root@server01 redis-stable]# ls -ll /etc/redis/
total 64
-rw-r--r-- 1 root root 62203 Dec 5 09:32 6379.conf
[root@server01 redis-stable]#
image
将redis的启动脚本复制一份放到/etc/init.d目录下
[root@server01 utils]# cp redis_init_script /etc/init.d/redisd
[root@server01 utils]#
[root@server01 utils]# ls -ll /etc/init.d/redisd
-rwxr-xr-x 1 root root 1352 Dec 5 09:34 /etc/init.d/redisd
[root@server01 utils]#
image
设置redis开机自启动
[root@server01 utils]# cd /etc/init.d/
[root@server01 init.d]# ls
functions netconsole network README redisd
[root@server01 init.d]# chkconfig redisd on
[root@server01 init.d]#
image
使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出
#!/bin/sh
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。
image
启动以及关闭redis
[root@server01 init.d]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
[root@server01 init.d]#
[root@server01 init.d]# service redisd stop

可以从上面看出，当配置了redis的密码之后，停止redis的时候是需要认证的。
配置启动脚本使用密码，解决
停止(NOAUTH Authentication required)的问题
修改redis启动脚本
[root@server01 ~]# vim /etc/init.d/redisd
# 修改添加 -a "密码"
#$CLIEXEC -p $REDISPORT shutdown
$CLIEXEC -a "newpwd" -p $REDISPORT shutdown
