redis設定檔

主要遇到的問題是：redis.pid沒有找到

下面是我的設定檔

# By default Redis does not run as a daemon. Use 'yes' if you need it.# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.daemonize yes# When running daemonized, Redis writes a pid file in /var/run/redis.pid by# default. You can specify a custom pid file location here.

var/run的執行許可權

lrwxrwxrwx  1 root root        4 Feb 24 06:57 run -> /run

然後我用sudo touch redis.pid

root@ubuntu:/home/fuhui/redis-2.8.19/utils# pwd/home/fuhui/redis-2.8.19/utilsroot@ubuntu:/home/fuhui/redis-2.8.19/utils# sh redis_init_script stop/var/run/redis_6379.pid does not exist, process is not running

不知道是不是許可權的問題，修改o許可權

fuhui@ubuntu:/var/run$ sudo chmod o+wx redis.pid-rw-r--rwx 1 root       root          0 Jun 22 08:39 redis.pid

難道是服務並沒有重啟？

fuhui@ubuntu:/var/run$ ps -ef | grep 'redis'fuhui     2452     1  0 07:55 ?        00:00:04 redis-2.8.19/src/redis-server *:6379                 fuhui     2908  2756  0 08:46 pts/13   00:00:00 grep --color=auto redisfuhui@ubuntu:/var/run$ kill -9 2452fuhui@ubuntu:/var/run$ ps -ef | grep 'redis'fuhui     2910  2756  0 08:46 pts/13   00:00:00 grep --color=auto redis

重啟一下試試：
搞定，redis.pid裡有了pid號

關閉redis服務

root@ubuntu:/home/fuhui/redis-2.8.19/utils# sh redis_init_script stop/var/run/redis_6379.pid does not exist, process is not running

修改shell檔案
下面的是原檔案，我們要做的其實很簡單，只是把路徑修改成實際存放的就可以

#!/bin/sh## Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6379EXEC=/usr/local/bin/redis-serverCLIEXEC=/usr/local/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/etc/redis/${REDISPORT}.conf"case "$1" in    start)        if [ -f $PIDFILE ]        then                echo "$PIDFILE exists, process is already running or crashed"        else                echo "Starting Redis server..."                $EXEC $CONF        fi        ;;    stop)        if [ ! -f $PIDFILE ]        then                echo "$PIDFILE does not exist, process is not running"        else                PID=$(cat $PIDFILE)                echo "Stopping ..."                $CLIEXEC -p $REDISPORT shutdown                while [ -x /proc/${PID} ]                do                    echo "Waiting for Redis to shutdown ..."                    sleep 1                done                echo "Redis stopped"        fi        ;;    *)        echo "Please use start or stop as first argument"        ;;esac

修改如下：

root@ubuntu:/home/fuhui/redis-2.8.19/utils# cp redis_init_script ../redis_script

看一下proc下是否存在pid

fuhui@ubuntu:/proc$ cd /proc/fuhui@ubuntu:/proc$ ls -lh | grep 2912dr-xr-xr-x  9 root       root          0 Jun 22 08:47 2912
