方法一:使用命令安装(前提是已经安装了EPEL)。 安装redis: yum -y install redis 启动/停止/重启 Redis 启动服务: 1 systemctl start redis.service 停止服务: systemctl stop redis.service 重启服务:
systemctl restart redis.service 检查状态:
[root@idoseek ~]# systemctl status redis.service redis.service - Redis persistent key-value database Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled) Active: active (running) since 二 2014-10-21 21:37:22 EDT; 5h 26min ago Main PID: 30413 (redis-server) CGroup: /system.slice/redis.service └─30413 /usr/bin/redis-server 127.0.0.1:6379 10月 21 21:37:22 idoseek.com systemd[1]: Started Redis persistent key-value database. 随系统启动服务:
[root@idoseek ~]# systemctl enable redis.service ln -s '/usr/lib/systemd/system/redis.service' '/etc/systemd/system/multi-user.target.wants/redis.service' 关闭随机启动:
[root@idoseek ~]# systemctl disable redis.service rm '/etc/systemd/system/mult(www.111cn.net)i-user.target.wants/redis.service' 方法二:编译安装 下载安装编译:
# wget http://download.redis.io/releases/redis-2.8.17.tar.gz # tar xzf redis-2.8.17.tar.gz # cd redis-2.8.17 # make # make install 设置配置文件路径:
# mkdir -p /etc/redis && cp redis.conf /etc/redis 修改配置文件:
# vim /etc/redis/redis.conf 修改为: daemonize yes 启动Redis:
# /usr/local/bin/redis-server /etc/redis/redis.conf #关闭服务
redis-cli shutdown 或者在cli中执行shutdown
redis 127.0.0.1:6379> shutdown 清除缓存
redis-cli flushall 更多文档请参考软件包内的“README”文件。 查看状态 : # ss -nlp|grep redis 或者 # ps -ef | grep redis 下面介绍为PHP添加redis插件。 从官网下载最新的拓展,地址:http://pecl.php.net/package/redis或者https://github.com/phpredis/phpredis #wget http://pecl.php.net/get/redis-2.2.5.tgz #phpize #./configure --prefix=/opt/redis --enable-redis --with-php-config=/opt/php/bin/php-config #make && make install 把拓展添加至php.ini,重启php-fpm: service php-fpm restart from:http://www.111cn.net/sys/CentOS/85292.htm
错误描述
zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory zmalloc.h:55:2: error: #error "Newer version of jemalloc required" make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory `/data0/src/redis-2.6.2/src' make: *** [all] Error 2
原因分析
在README 有这个一段话。
Allocator --------- Selecting a non-default memory allocator when building Redis is done by setting the `MALLOC` environment variable. Redis is compiled and linked against libc malloc by default, with the exception of jemalloc being the default on Linux systems. This default was picked because jemalloc has proven to have fewer fragmentation problems than libc malloc. To force compiling against libc malloc, use: % make MALLOC=libc To compile against jemalloc on Mac OS X systems, use: % make MALLOC=jemalloc
说关于分配器allocator, 如果有MALLOC 这个 环境变量, 会有用这个环境变量的 去建立Redis。
而且libc 并不是默认的 分配器, 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。
但是如果你又没有jemalloc 而只有 libc 当然 make 出错。 所以加这么一个参数。
解决办法
make MALLOC=libc
