Linux+Nginx+php7 redis扩展安装

cat > /etc/profile.d/redis.sh << EOF
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/bin’
EOF
. /etc/profile

1. 源码安装redis

创建用户和组
groupadd redis
useradd -r -g redis -s /sbin/nologin -M redis

安装redis
cd /usr/local/src/
wget http://download.redis.io/releases/redis-3.2.5.tar.gz
tar -zxvf redis-3.2.5.tar.gz
cd redis-3.2.5/
make PREFIX=/usr/local/redis
make install

创建目录，授权
mkdir -p /usr/local/redis/data
mkdir -p /usr/local/redis/etc
mkdir -p /var/run/redis
mkdir -p /var/log/redis

chown -R redis:redis /usr/local/redis
chown -R redis:redis /var/run/redis
chown -R redis:redis /var/log/redis

配置文件
cp redis.conf /usr/local/redis/etc/
vim /usr/local/redis/etc/redis.conf

tcp-backlog 128 　　#tcp队列长度，CentOS系统默认为128，此值不应该大于操作系统的该值
daemonize yes 　　　#改为yes，保证redis可以后台运行
pidfile /var/run/redis/redis.pid #redis pid
logfile “/var/log/redis/redis.log” #redis日志
dir /usr/local/redis/data/ #redis数据存储目录

—— 可选配置 ——

slaveof 192.168.1.66 6379 　　　　 #主从复制，在副机上配置，例：IP 192.168.1.66，端口 6379

save 60 10000 #快照，例：60s内10000个更改就保存

appendonly yes #AOF持久化

添加环境变量
cat > /etc/profile.d/redis.sh << EOF
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/bin’
EOF
. /etc/profile

或者
vim /etc/profile
修改为下面内容，保存退出
PATH=/usr/local/mysql/bin:/usr/local/php/bin:/usr/local/redis/bin:$PATH
使/etc/profile里的配置立即生效
source /etc/profile

创建服务
vim /etc/init.d/redisd

添加如下内容

!/bin/sh

#

chkconfig: 35 84 16

Simple Redis init.d script conceived to work on Linux systems

as it does use of the /proc filesystem.

. /etc/rc.d/init.d/functions
. /etc/sysconfig/network

[ “$NETWORKING” = “no” ] && exit 0

REDISPORT=6379
BASEDIR=/usr/local/redis
EXEC=BASEDIR/bin/redis−serverCLIEXEC=BASEDIR/bin/redis-cli

PIDFILE=/var/run/redis/redis.pid
CONF=”$BASEDIR/etc/redis.conf”

function start() {
if [ -f PIDFILE]thenecho“PIDFILE exists, process is already running or crashed”
else
echo -n “Starting Redis server…”
daemon –user=redis –pidfile=PIDFILEEXEC CONF  
                #EXEC CONF  
                echo  
        fi  
}  
function stop() {  
        if [ ! -fPIDFILE ]
then
echo “PIDFILEdoesnotexist,processisnotrunning”elsePID=(cat PIDFILE)  
                echo “Stopping …”  
                #CLIEXEC -p REDISPORTshutdownkillproc−pPIDFILE EXEC -INT  
                echo -n “Waiting for Redis saving data & shutdown .”  
                while [ -x /proc/{PID} ]
do
sleep 1
echo -n “.”
done
echo -e “\nRedis stopped”
fi
}

case “1”instart)start;;stop)stop;;status)status−pPIDFILE $EXEC
;;
restart)
stop
start
;;
*)
echo “Please use start or stop as first argument”
;;
esac

为redisd添加可执行权限

chmod +x /etc/init.d/redisd

将redis加入系统服务

chkconfig –add redisd

启动redis

service redisd start

1. php-redis扩展安装

wget http://101.96.10.64/pecl.php.net/get/redis-3.1.3.tgz
tar zxvf redis-3.1.3.tgz
cd redis-3.1.3
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config
make && make install
vim /usr/local/php/etc/php.ini

添加extension = redis.so

service php-fpm restart
php -m

查看是否支持redis

测试扩展库是否正常运行
php tests/TestRedis.php –class Redis
