• php切换版本之后 redis 安装使用


    一:redis安装
    Download, extract and compile Redis with:

        $ wget http://download.redis.io/releases/redis-3.0.4.tar.gz
        $ tar xzf redis-3.0.4.tar.gz
        $ cd redis-3.0.4
        $ make

    编译完成将:redis-server  redis-cli 和上级目录redis.conf  复制到 /usr/local/redis目录下 并将daemonize改为yes

    启动redis: ./redis-server redis.conf


    The binaries that are now compiled are available in the src directory. Run Redis with:

        $ redis-server

    You can interact with Redis using the built-in client:

        $ redis-cli

    redis> set name ruanqin
    OK
    redis> get name
    "ruanqin"
    这里无法启动:

    错误信息如下:

    PHP Warning: php Startup: redis: Unable to initialize module
    Module compiled with module API=20050922
    PHP compiled with module API=20090626
    These options need to match in Unknown on line 0
    

    首先先说下这种错误出现的原因:

    执行编译源码包执行phpize的版本与当前php环境中phpize的版本不一致造成的,也有可能和你切换的php版本有关系,我就是切换版本之后重新安装的解决办法:

    1、删除编译过的源码包phpredis-master以及对应目录中的redis.so重新解压phpredis-master

    2、检测/usr/sbin目录下是否存在php php-config php-cgi phpize文件,如果存在删除这些文件 重新建立对应的软连接到这个目录。

    ln -s php /usr/local/php/bin/php
    ln -s php-cgi /usr/local/php/bin/php-cgi
    ln -s php-config /usr/local/php/bin/php-config
    ln -s phpize /usr/local/php/bin/phpize
    

    以上目录请以php的当前安装目录为准。

    3、重新进入phpredis-master目录进行安装即可。

    二、php扩展:
    更多版本:http://pecl.php.net/package/redis

        wget http://pecl.php.net/get/redis-2.2.5.tgz
        #解压
        tar zxvf redis-2.2.5.tgz
        #进入安装目录
        cd redis-2.2.5
        /usr/local/php/bin/phpize
        #配置
        ./configure --with-php-config=/usr/local/php/bin/php-config
        #编译安装
        make && make install

    安装完成之后,出现下面的安装路径
    /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/

    配置php支持
    #编辑配置文件,在最后一行添加以下内容

        vim /usr/local/php/etc/php.ini
        extension="redis.so"

    这个时候phpinfo()就可以看到redis扩展了。

    redis 服务器重启自启动命令 

    在/etc/init.d/目录下创建redis  复制内容

    #!/bin/sh
    #
    # redis - this script starts and stops the redis-server daemon
    #
    # chkconfig:   - 85 15 
    # description:  Redis is a persistent key-value database
    # processname: redis-server
    # config:      /etc/redis/redis.conf
    # config:      /etc/sysconfig/redis
    # pidfile:     /var/run/redis.pid
    
    # Source function library.
    . /etc/rc.d/init.d/functions
    
    # Source networking configuration.
    . /etc/sysconfig/network
    
    # Check that networking is up.
    [ "$NETWORKING" = "no" ] && exit 0
    
    redis="/usr/local/redis/redis-server"
    prog=$(basename $redis)
    
    REDIS_CONF_FILE="/usr/local/redis/redis.conf"
    
    [ -f /etc/sysconfig/redis ] && . /etc/sysconfig/redis
    
    lockfile=/var/lock/subsys/redis
    
    start() {
        echo "start test!"
        [ -x $redis ] || exit 5
        [ -f $REDIS_CONF_FILE ] || exit 6
        echo "test successful!"
        echo -n $"Starting $prog: "
        daemon $redis $REDIS_CONF_FILE
        retval=$?
        echo
        [ $retval -eq 0 ] && touch $lockfile
        return $retval
    }
    
    stop() {
        echo -n $"Stopping $prog: "
        killproc $prog -QUIT
        retval=$?
        echo
        [ $retval -eq 0 ] && rm -f $lockfile
        return $retval
    }
    
    restart() {
        stop
        start
    }
    
    reload() {
        echo -n $"Reloading $prog: "
        killproc $redis -HUP
        RETVAL=$?
        echo
    }
    
    force_reload() {
        restart
    }
    
    rh_status() {
        status $prog
    }
    
    rh_status_q() {
        rh_status >/dev/null 2>&1
    }
    
    case "$1" in
        start)
            rh_status_q && exit 0
            $1
            ;;
        stop)
            rh_status_q || exit 0
            $1
            ;;
        restart|configtest)
            $1
            ;;
        reload)
            rh_status_q || exit 7
            $1
            ;;
        force-reload)
            force_reload
            ;;
        status)
            rh_status
            ;;
        condrestart|try-restart)
            rh_status_q || exit 0
            ;;
        *)
            echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
            exit 2
    esac

    最后记得给他个权限 755就可以了

    特殊情况下redis启动失败可以加个脚本文件:

    #!/bin/bash
    # Source function library.
    . /etc/rc.d/init.d/functions
    
    # Source networking configuration.
    . /etc/sysconfig/network
    
    ret=$(ps aux|grep redis|awk '{print $2,$11}'|grep redis|head -1|awk '{print $1}')
    
    if [ -z $ret ]
    then
        echo 'ready to start'
        echo "service redis start"
        eval "service redis start"
    else
        echo 'fk,'
    fi

    crontab 中写入:     */1 * * * * /bin/bash /www/shell/redis.sh > /var/log/redis_err.log 2>&1 &
