Linux上完美安装memcache(含自启动)

[size=large][size=medium]

  • 目录(?)[-]
  • 一安装依赖库libevent
  • 二安装memcache源代码安装
  • 三安装memcache安装包安装--待补充
  • 四配置为自启动服务

一、安装依赖库libevent

1.进入/usr/lib目录,使用命令:ls-allibevent查看是否已安装,如果已安装且版本低于2.0.21,则先通过:rpm-elibevent—nodeps进行卸载。

2.上传libevent-2.0.21-stable.tar.gz至非usr目录下(因为libevent将安装到usr目录,所以最好换个目录存放安装文件,例如/home),然后解压。

3.切换到解压后的libevent主目录:cdlibevent-2.0.21-stable

4.依次执行:

1)./configure-prefix=/usr(或./configure--program-prefix=/usr)

2)make

3)makeinstall

注意:

1)执行makeinstall时可能需要root权限。

2)libevent会安装到/usr/lib下

5.测试libevent是否安装成功:ls-al/usr/lib|greplibevent出现类似下图结果则表示安装成功:

6.有时候,libevent会被安装目录到/usr/local/lib下(采用默认安装就会安装到这个目录),这种情况下除了按照1-5的步骤操作外,还需要建立libevent-2.0.so.5到/usr/lib的软连接,这样其他程序运行时才能找到libevent库:

ln–s/usr/local/lib/libevent-2.0.so.5/usr/lib/libevent-2.0.so.5

7.在64位机器上还需做一个64位库的链接,否则运行memcache时会报找不到libevent的错误

ln-s/usr/lib/libevent-2.0.so.5/usr/lib64/libevent-2.0.so.5

二、安装memcache(源代码安装)

1.上传memcached-1.4.15.tar.gz至非usr目录下(因为memcached-1.4.15将安装到usr目录,所以最好换个目录存放安装文件,例如/home),然后解压。

2.切换到解压后的memcache主目录:cdmemcached-1.4.15

3.依次执行:

1)./configure-prefix=/usr/local/memcached--with-libevent=/usr

2)make

3)makeinstall

注意:

1)执行makeinstall时可能需要root权限。

2)memcache会安装到/usr/local/memcached下

三、安装memcache(安装包安装)--待补充

四、配置为自启动服务

1.编写memcached自启动脚本或直接使用memcached安装包中的脚本(位置如下,本文使用官方自带的脚本)

2.修改自启动脚本(红色部分标识,中文注释仅限本文提示用,安装包没有)

#! /bin/sh
#
# chkconfig: - 55 45
# description:  The memcached daemon is a network memory cache service.
# processname: memcached
# config: /etc/sysconfig/memcached

# Source function library - for other linux
#. /etc/rc.d/init.d/functions
# Source function library - for suse linux
. /lib/lsb/init-functions
PORT=11211
USER=root

#最大连接数,根据实际需求修改
MAXCONN=1024

#最大内存量,单位M
CACHESIZE=128

OPTIONS=""

if [ -f /etc/sysconfig/memcached ];then
    . /etc/sysconfig/memcached
fi

# Check that networking is up.
if [ "$NETWORKING" = "no" ]
then
    exit 0
fi

RETVAL=0
prog="memcached"

start () {
    echo -n $"Starting $prog: "
    # insure that /usr/local/memcached has proper permissions
    chown $USER /usr/local/memcached
    /usr/local/memcached/bin/memcached -d -p $PORT -u $USER  -m $CACHESIZE -c $MAXCONN -P /usr/local/memcached/memcached.pid $OPTIONS
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached
}

stop () {
    echo -n $"Stopping $prog: "
    killproc memcached
    RETVAL=$?
    echo
    if [ $RETVAL -eq 0 ] ; then
        rm -f /var/lock/subsys/memcached
        rm -f /usr/local/memcached/memcached.pid
    fi
}

restart () {
    stop
    start
}

# See how we were called.
case "$1" in
    start)
        start
        ;;
    stop)
    stop
    ;;
    status)
    status memcached
    ;;
    restart|reload)
    restart
    ;;
    condrestart)
    [ -f /var/lock/subsys/memcached ] && restart || :
    ;;
    *)
    echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
    exit 1
esac
exit $?

3.将此脚本cp到/etc/init.d目录下并改名为memcached,然后执行chmoda+xmemcached,如下:

shell>cpmemcached.sysv/etc/init.d/memcached

shell>chmod755/etc/init.d/memcached

4.将memcached加入系统服务:

shell>chkconfig--addmemcached

shell>chkconfigmemcachedon

5.以服务方式运行memcached

shell>servicememcachedstart

以上如成功则重启下系统后查看下memcached是否已随系统启动
