centerOS 安装配置redis

安装：

# 下载/解压/编译/安装
wget http://download.redis.io/releases/redis-6.0.8.tar.gz
tar xzf redis-6.0.8.tar.gz
cd redis-6.0.8
make
make install
#默认安装到/usr/local/bin目录

配置：

复制配置文件redis.conf到/usr/local/redis/conf目录，目录要自己建

# 创建目录/复制配置文件/编辑配置文件
mkdir /usr/local/redis
mkdir /usr/local/redis/conf
cp redis.conf /usr/local/redis/conf
vim /usr/local/redis/conf/redis.conf
# 修改配置文件，daemonized  yes  //默认是 no

配置启动服务：

在/etc/init.d/目录下新建启动文件redis,内容如下：

###########################
# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database

PATH=${PATH}/usr/local/bin
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
#Redis密码
PASSWORD=yourPassword
PIDFILE=/var/run/redis_$REDISPORT.pid
CONF="/usr/local/redis/conf/redis.conf"
   
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 does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $REDIS_CLI -p $REDISPORT -a $PASSWORD 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
        exit 1
esac
##############################

设置文件权限

chmod +x /etc/init.d/redis

设置开机启动（我设置了不过没效果）

sudo chkconfig redis on

手动启动停止redis服务

service redis start   #或者 /etc/init.d/redis start
service redis stop   #或者 /etc/init.d/redis stop

查看服务是否启动

ps -ef | grep redis

 

编译错误：server.c:5303:15: error: ‘struct redisServer’ has no member named ‘maxmemory’

是gcc版本问题，当前版本为gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ，使用如下指令升级gcc，重新连接后会恢复到旧版本的gcc的

yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash

升级后使用gcc -v查看版本为gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC)
