CentOS 7环境下安装Redis
正如我们所知的那样,Redis是一个开源的、基于BSD许可证的,基于内存的、键值存储NoSQL数据库。Redis经常被视为一个数据结构服务器,因为Redis支持字符串strings、哈希hashes、列表lists、集合sets、有序集sorted sets等数据结构。Redis还支持像事务Transitions、发布和订阅这样的数据类型。有鉴于此,Redis经常被认为是更强大的Memcache。
本文主要讲述Redis在CentOS 7环境下的安装有什么不同。假定CentOS 7 Server已经就绪。
1、启用EPEL仓库
## RHEL/CentOS 7 64-Bit ## # wget http://dl.Fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm # rpm -ivh epel-release-7-5.noarch.rpm
要验证EPEL仓库是否建立成功,可以执行:
# yum repolist
2、通过Yum安装Redis
# yum -y update # yum install redis php-pecl-redis
把Redis添加到开机启动服务中:
# systemctl start redis-server.service # systemctl enable redis-server.service
检查Redis是否运行:
# systemctl is-active redis-server.service
3、安装Redis的Web管理客户端
phpRedisAdmin是一个免费开源的RedisWeb管理客户端,它提供了一个简单的界面来实现对Redis数据库的管理。
# git clone https://github.com/ErikDubbelboer/phpRedisAdmin.git # cd phpRedisAdmin/includes # cp config.sample.inc.php config.inc.php
要确保配置正确:
# nano config.inc.php
再把RedisAdmin配置文件添加到Apache服务器,文件的内容如下:
### nano /etc/httpd/conf.d/redisadmin.conf ### Now add the following ### # # Web Interface for RedisAdmin # <Directory "/downloads/phpRedisAdmin/"> Order Deny,Allow Deny from all Allow from 127.0.0.1 Allow from <your ipaddress> </Directory> Alias /redisAdmin /downloads/phpRedisAdmin Alias /redisadmin /downloads/phpRedisAdmin
创建一个Bash脚本来确保Redis的正常运行,内容如下:
### nano /scripts/redis-check.sh #!/bin/bash PS=$(which ps) GREP=$(which grep) WHEN=$(date +"%Y-%m-%d-%H:%M:%S") if ! $PS aux | $GREP "redis.conf" | $GREP -v grep 2>&1 > /dev/null; then /etc/init.d/redis restart echo 'Restarted Redis @' $WHEN fi #Check Second instance if ! $PS aux | $GREP "redis2.conf" | $GREP -v grep 2>&1 > /dev/null; then /etc/init.d/redis2 restart echo 'Restarted Redis2 @' $WHEN fi
确保脚本是可执行的:
# chmod +x /scripts/redis-check.sh
通过定时器cron来保证脚本的执行,每3分钟运行一次:
### nano /var/spool/cron/root */3 * * * * /bin/bash /script/redis-check.sh >> /var/log/redis-check.log
OK,至此完工。
