Redis安裝配置

一)下載源碼，編譯安裝

# wget http://redis.googlecode.com/files/redis-2.2.8.tar.gz 
# tar xf redis-2.2.8.tar.gz 
# cd redis 
# make  
# 網上說不能make install,可我這就是可以，奇怪，省去了手動copy redis命令的步驟
# make install  

make install後顯示

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，請將redis.conf copy一份到/etc/目錄下

daemonize no 

改成

daemonize yes 

這兩個參數

loglevel warning  
logfile /var/log/redis.log  

取消注釋

syslog-enabled no #這個改成syslog-enabled yes
syslog-facility local0

數據文件目錄

# 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 

內存，連接數設置

maxmemory 256000000
maxclients 500

三)啟動腳本

#!/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 

配置啟動腳本

#chmod 755 /etc/init.d/redis 
# chkconfig --add redis 
# chkconfig redis on 

四)啟動

在正式啟動redis之前，先創建數據目錄

# mkdir /var/db/redis 

否則會出現下面的錯誤

[3030] 27 May 16:50:38 # Can't chdir to '/var/db/redis': No such file or directory 

同時配置內核參數

sysctl vm.overcommit_memory=1 

否則提示錯誤

# 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. 

最後，啟動

[root@web ~]# /etc/init.d/redis start 
Starting Redis Server:                                     [  OK  ] 

PS:不利用腳本啟動，關閉redis的命令

啟動 
# redis-server /etc/redis.conf 
 
關閉 
# redis-cli shutdown 
 
關閉某個端口上的redis 
# redis-cli -p port shutdown
