redis安装及配置

redis官网下载地址,

1 redis单机版本安装

上传redis-3.0.7.tar.gz到application目录下

mkdir -p /application
cd /application
tar xzvf redis-3.0.7.tar.gz
cd redis-3.0.7

make  MALLOC=jemalloc
make PREFIX=/application/redis-3.0.7 install
ln -s /application/redis-3.0.7/ /application/redis
cd ../redis
mkdir logs     创建日志目录
mkdir redisData 创建持久化数据目录
cd ..
rm -f redis-3.0.7.tar.gz

vi /etc/profile，添加以下redis的环境变量配置，并通过source /etc/profile生效。

export REDIS_HOME=/application/redis
export PATH=$PATH:$REDIS_HOME/bin

执行以下命令，对redis服务器进行启动、关闭操作

# redis启动
redis-server /application/redis/redis.conf &
# redis关闭
redis-cli  shutdown
redis-cli -p 6379 shutdown 也可以执行此命令
# 查看redis进程
ps -ef | grep redis

2 redis主从集群Sentinel模式

port 26379
daemonize yes
sentinel monitor mymaster 192.168.5.174 6379 2
sentinel down-after-milliseconds mymaster 60000
sentinel failover-timeout mymaster 180000
sentinel parallel-syncs mymaster 1

运行redis sentinel

redis-server /application/redis/sentinel.conf --sentinel 运行sentinel
redis-cli -p 26379 sentinel masters 查看当前的master节点情况
redis-cli -p 26379 shutdown 停掉sentinel

3 redis.conf

3.2以后的版本会有变化

notify-keyspace-events Ex
logfile "/application/redis/logs/redis.log"
dir /application/redis/redisData
slaveof 192.168.5.174 6379 仅在slave节点增加此配置。

4 redis开机启动

更改

redis.conf

将redis改成守护进程,将daemonize调整为yes

daemonize yes

定义/etc/init.d/redis脚本,注意redis的目录

# chkconfig:   2345 90 10
# description:  redis is a persistent key-value database
###########################
###########################
PATH=/usr/local/bin:/sbin:/usr/bin:/bin

更改权限

chmod 755 redis

执行启动测试，

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

设置开机启动

5 过程遇到的问题

5.1 syntax error near unexpected token newline

如果出现

syntax error near unexpected token

newline’

的异常,则执行命令

dos2unix /etc/init.d/redis

，将回车换行改成linux的$,可以通过

cat -A /etc/init.d/redis

核实是否修正完毕,详细解决办法参照[关于报错“syntax error near unexpected token

”和回车换行](http://blog.csdn.net/windless0530/article/details/6077654)

5.2 /var/run/redis.pid exists, process is already running or crash
4000
ed

执行命令

rm -rf /var/run/redis.pid

，将之前的删掉，原因是之前的redis通过其他的方式正在运行，采用新的方式redis就没法启动了。

5.3 service redis does not support chkconfig

必须把下面两行注释放在/etc/init.d/redis文件靠前的注释中：

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

详细可以参考 service redis does not support chkconfig的解决办法
