配置编译环境

# yum install gcc-c++

编译

# make

如果报错:jemalloc/jemalloc.h：没有那个文件或目录
使用:

make MALLOC=libc

# make install
cd src && make install
make[1]: 进入目录“/usr/local/redis/redis-4.0.2/src”
    CC Makefile.dep
make[1]: 离开目录“/usr/local/redis/redis-4.0.2/src”
make[1]: 进入目录“/usr/local/redis/redis-4.0.2/src”

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

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: 离开目录“/usr/local/redis/redis-4.0.2/src”

启动Redis-server

# redis-server

Ctrl+shift+t 重开一个终端tab
查看Redis

$ ps -ef | grep redis
root       5188   3749  0 22:46 pts/0    00:00:00 redis-server *:6379
xcx        5235   5200  0 22:46 pts/1    00:00:00 grep --color=auto redis

启动Redis-client

$ redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> 

基本安装完成

此时重启系统,发现redis并没有启动,所以需要设置redis自启,
这里我们进入utils文件夹

# cd /usr/local/redis/redis-4.0.2/utils

切换root用户,执行里面的install_server.sh该文件会帮助我们将redis服务添加到系统自启服务中

# ./install_server.sh 
Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] 
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server] 
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!
Successfully added to runlevels 345!
Starting Redis server...
Installation successful!

这是再重启系统,就会发现redis跟随系统自动启动了

如果需要外部访问,需要修改配置文件:

# vim /etc/redis/6379.conf

#bind 127.0.0.1
bind 0.0.0.0
#daemonize no
daemonize yes

防火墙开放6379端口

# firewall-cmd --permanent --zone=public --add-port=6379/tcp
# firewall-cmd --reload

重启redis服务后就可以外部访问了
