安装前提：
在安装Redis之前首要先做的是安装Unix的Tcl工具，如果不安装的话后期将无法对Redis进行测试。

1：安装Redis测试依赖tcl8.6.3

#进入src目录
cd /usr/local/src
#下载资源包
wget http://47.96.19.7/source/redis/tcl8.6.3-src.tar.gz
#解压包
tar -zxvf tcl8.6.3-src.tar.gz
#进入编译目录 
cd tcl8.6.3/unix/
#编译配置
./configure
#安装 分两步走
make
make install

2：安装Redis

#进入src目录
cd /usr/local/src
#下载资源包
wget http://47.96.19.7/source/redis/redis-3.0.5.tar.gz
#解压包
tar -zxvf redis-3.0.5.tar.gz
#进入编译目录
cd redis-3.0.5
#安装到/usr/local/redis下
make
make PREFIX=/usr/local/redis install

3：测试安装

cd /usr/local/src/redis-3.0.5/src
make test

image

显示测试成功！
4：配置Redis

cd /usr/local/src/redis-3.0.5/
cp redis.conf /usr/local/redis/
vim /usr/local/redis/redis.conf
#修改后，redis作为守护进程在服务端运行
daemonize yes
#修改默认的端口号6379为6399
port 6399

5：设置redis服务器自启动

#创建redis启动命令
vim /etc/init.d/redis

复制以下代码

# chkconfig: 2345 10 90
# description: Start and Stop redis
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6399 #实际环境而定
EXEC=/usr/local/redis/bin/redis-server #实际环境而定
REDIS_CLI=/usr/local/redis/bin/redis-cli #实际环境而定

PIDFILE=/var/run/redis.pid
CONF="/usr/local/redis/redis.conf" #实际环境而定

case "$1" in
        start)
                if [ -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is already running or crashed."
                else
                        echo "Starting Redis server..."
                        $EXEC $CONF
                fi
                if [ "$?"="0" ]
                then
                        echo "Redis is running..."
                fi
                ;;
        stop)
                if [ ! -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is not running."
                else
                        PID=$(cat $PIDFILE)
                        echo "Stopping..."
                        $REDIS_CLI -p $REDISPORT SHUTDOWN
                        while [ -x $PIDFILE ]
                        do
                                echo "Waiting for Redis to shutdown..."
                                sleep 1
                        done
                        echo "Redis stopped"
                fi
                ;;
        restart|force-reload)
                ${0} stop
                ${0} start
                ;;
        *)
                echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
             exitxit 1
esac

赋予权限

chmod +x /etc/init.d/redis

开启服务自启动

chkconfig redis on

6：启动或关闭服务

service redis start
#没有设置密码的关闭方式
service redis stop
#设置了密码的关闭方式
/usr/local/bin/redis-cli -h 127.0.0.1 -p 6399　-a yourpassword shutdown

7：测试redis数据写入和读取

cd /usr/local/redis/bin
./redis-cli -p 6399
127.0.0.1:6399> set test 123
OK
127.0.0.1:6399> get test
"123"
127.0.0.1:6399> exit

测试成功！

其他：启动redis错误处理

A-overcommit_memory错误

 WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

解决方法：

编辑/etc/sysctl.conf ，改vm.overcommit_memory=1，然后sysctl -p 使配置文件生效

B-TCP设置太小问题

The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128

解决方法：

编辑/etc/sysctl.conf ，添net.core.somaxconn= 1024 然后执行sysctl -p

另外一种安装:
安装编译php7
　1.下载

下载地址：http://pecl.php.net/package/redis

下载目录我放在/data/download/php下

cd到下载目录，下载：wget http://pecl.php.net/get/redis-3.1.2.tgz

2.解压

解压到当前目录 tar -zxvf redis-3.1.2.tgz

3.安装

cd redis-3.1.2目录下

在该目录下用phpize生成configure配置文件：直接运行/usr/local/php7/bin/phpize

运行/usr/local/php7/bin/phpize时出现：
Configuring for: 
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

cd /usr/src

wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz

tar -zvxf m4-1.4.9.tar.gz

cd m4-1.4.9/

./configure && make && make install

cd ../

wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz

tar -zvxf autoconf-2.62.tar.gz

cd autoconf-2.62/

./configure && make && make install

yum install m4
yum install autoconf

然后就是配置、编译、安装全部在该目录下完成

./configure --with-php-config=/usr/local/php7/bin/php-config

make

make install

make install后会看到Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/

该目录就是redis.so文件的生成目录

ll /usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/

看到redis.so就说明安装成功了

配置支持PHP7：
　　vim /usr/local/php7/etc/php.ini

添加extension=redis.so

:wq!
重启php-fpm
