# 1、安装gcc依赖 #

由于 redis 是用 C 语言开发，安装之前必先确认是否安装 gcc 环境（gcc -v），如果没有安装，执行以下命令进行安装

>yum install -y gcc tcl #装 gcc 编译器和 redis 测试使用到的 tcl 库

安装6版本的redis，gcc版本一定要5.3以上，centos6.6默认安装4.4.7；centos7.5.1804默认安装4.8.5，这里要升级gcc了。  
可以通过命令`gcc -v`可以查看gcc的版本，检查版本是否过低。升级命令

>yum -y install centos-release-scl && yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils && scl enable devtoolset-9 bash
    #注意：scl命令启用只是临时的，退出xshell或者重启就会恢复到原来的gcc版本。
    #如果要长期生效的话，执行如下：
    >echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

# 2、下载安装 #

> wget https://download.redis.io/releases/redis-6.0.10.tar.gz
    > tar xzf redis-6.0.10.tar.gz
    > cd redis-6.0.10
    > make
    >make install PREFIX=/usr/local/redis #安装并指定安装目录

## 2.1 安装成系统服务 ##

>./utils/install_server.sh

### 2.1.1 报错Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry ###

Welcome to the redis service installer
    This script will help you easily set up a running redis server
    
    This systems seems to use systemd.
    Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!

打开install\_server.sh，注释掉下面的内容：

#_pid_1_exe="$(readlink -f /proc/1/exe)"
    #if [ "${_pid_1_exe##*/}" = systemd ]
    #then
    #	echo "This systems seems to use systemd."
    #	echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
    #	exit 1
    #fi
    #unset _pid_1_exe

### 2.2.2 报错Mmmmm...  it seems like you don't have a redis executable. Did you run make install yet? ###

按如下修改

### 2.2.3 执行后，查看启动状态 ###

>systemctl status redis_6379
    Unit redis.service could not be found.
    [root@iZ2zeck0io750hybqc9ixiZ ~]# systemctl status redis_6379
    ● redis_6379.service - LSB: start and stop redis_6379
       Loaded: loaded (/etc/rc.d/init.d/redis_6379; bad; vendor preset: disabled)
       Active: inactive (dead)
         Docs: man:systemd-sysv-generator(8)

## 2.2 文件位置 ##

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

# 3、修改配置文件 #

修改redis.conf 配置文件

*  daemonize修改为yes即可守护进程模式后台启动。
 *  密码默认为空、若要设置密码、可以通过放开注释\# requirepass foobared
 *  远程访问需要在将bind 127.0.0.1配置注释，修改protected-mode no，重启即可。
