Redis安装配置
一)下载源码,编译安装
# wget http://redis.googlecode.com/files/redis-2.2.8.tar.gz # tar xf redis-2.2.8.tar.gz # cd redis # make # 网上说不能make install,可我这就是可以,奇怪,省去了手动copy redis命令的步骤 # make install
make install后显示
cd src && make install make[1]: Entering directory `/usr/local/src/redis-2.2.8/src' cd ../deps/hiredis && make static ARCH="" make[2]: Entering directory `/usr/local/src/redis-2.2.8/deps/hiredis' make[2]: Nothing to be done for `static'. make[2]: Leaving directory `/usr/local/src/redis-2.2.8/deps/hiredis' cd ../deps/linenoise && make ARCH="" make[2]: Entering directory `/usr/local/src/redis-2.2.8/deps/linenoise' make[2]: `linenoise_example' is up to date. make[2]: Leaving directory `/usr/local/src/redis-2.2.8/deps/linenoise' cd ../deps/hiredis && make static make[2]: Entering directory `/usr/local/src/redis-2.2.8/deps/hiredis' make[2]: Nothing to be done for `static'. make[2]: Leaving directory `/usr/local/src/redis-2.2.8/deps/hiredis' cc -o redis-benchmark -std=c99 -pedantic -O2 -Wall -W -lm -pthread -g -rdynamic -ggdb ae.o anet.o redis-benchmark.o sds.o adlist.o zmalloc.o ../deps/hiredis/libhiredis.a cc -o redis-cli -std=c99 -pedantic -O2 -Wall -W -lm -pthread -g -rdynamic -ggdb anet.o sds.o adlist.o redis-cli.o zmalloc.o release.o ../deps/hiredis/libhiredis.a ../deps/linenoise/linenoise.o Hint: To run 'make test' is a good idea ;) mkdir -p /usr/local/bin cp -p redis-server /usr/local/bin cp -p redis-benchmark /usr/local/bin cp -p redis-cli /usr/local/bin cp -p redis-check-dump /usr/local/bin cp -p redis-check-aof /usr/local/bin make[1]: Leaving directory `/usr/local/src/redis-2.2.8/src'
二)修改配置
修改配置之前,请将redis.conf copy一份到/etc/目录下
daemonize no
改成
daemonize yes
这两个参数
loglevel warning logfile /var/log/redis.log
取消注释
syslog-enabled no #这个改成syslog-enabled yes syslog-facility local0
数据文件目录
# The working directory. # # The DB will be written inside this directory, with the filename specified # above using the 'dbfilename' configuration directive. # # Also the Append Only File will be created inside this directory. # # Note that you must specify a directory here, not a file name. dir /var/db/redis
内存,连接数设置
maxmemory 256000000 maxclients 500
三)启动脚本
#!/bin/bash # # Init file for redis # # chkconfig: - 80 12 # description: redis daemon # # processname: redis # config: /etc/redis.conf # pidfile: /var/run/redis.pid . /etc/init.d/functions BIN="/usr/local/bin" CONFIG="/etc/redis.conf" PIDFILE="/var/run/redis.pid" ### Read configuration [ -r "$SYSCONFIG" ] && source "$SYSCONFIG" RETVAL=0 prog="redis-server" desc="Redis Server" start() { if [ -e $PIDFILE ];then echo "$desc already running...." exit 1 fi echo -n $"Starting $desc: " daemon $BIN/$prog $CONFIG RETVAL=$? echo [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog return $RETVAL } stop() { echo -n $"Stop $desc: " killproc $prog RETVAL=$? echo [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog $PIDFILE return $RETVAL } restart() { stop start } case "$1" in start) start ;; stop) stop ;; restart) restart ;; condrestart) [ -e /var/lock/subsys/$prog ] && restart RETVAL=$? ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $0 {start|stop|restart|condrestart|status}" RETVAL=1 esac exit $RETVAL
配置启动脚本
#chmod 755 /etc/init.d/redis # chkconfig --add redis # chkconfig redis on
四)启动
在正式启动redis之前,先创建数据目录
# mkdir /var/db/redis
否则会出现下面的错误
[3030] 27 May 16:50:38 # Can't chdir to '/var/db/redis': No such file or directory
同时配置内核参数
sysctl vm.overcommit_memory=1
否则提示错误
# WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. #To fix this issue #add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command #'sysctl vm.overcommit_memory=1' for this to take effect.
最后,启动
[root@web ~]# /etc/init.d/redis start Starting Redis Server: [ OK ]
PS:不利用脚本启动,关闭redis的命令
启动 # redis-server /etc/redis.conf 关闭 # redis-cli shutdown 关闭某个端口上的redis # redis-cli -p port shutdown
