CentOS6.9源码编译安装memcached

这篇笔记记录了在CentOS6.9中源码编译安装libevent和memcached,设置开机启动,以及telnet测试的过程

1.安装所需依赖

yum install wget gcc gcc-c++

2.源码编译安装libevent库
#创建并进入源码存放目录

mkdir -p /usr/local/src
cd /usr/local/src

#下载,解压

wget -c https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz
tar -zxvf libevent-2.1.8-stable.tar.gz

#配置,编译,安装

cd libevent-2.1.8-stable
./configure --prefix=/usr/local/libevent-2.1.8
make -j4
make install

3.安装memcached
#进入源码目录,下载,解压

cd /usr/local/src
wget -c http://www.memcached.org/files/memcached-1.5.12.tar.gz
tar -zxvf memcached-1.5.12.tar.gz

#配置,编译,安装

cd memcached-1.5.12
./configure --prefix=/usr/local/memcached \
--with-libevent=/usr/local/libevent-2.1.8
make -j4
make install

4.设置启动脚本
#创建系统用户,不允许登陆和不创建主目录

useradd -r -s /sbin/nologin -M memcached

#复制脚本至init.d目录下

cp /usr/local/src/memcached-1.5.12/scripts/memcached.sysv /etc/init.d/memcached

#编辑脚本

vim /etc/init.d/memcached

#注释以下配置

#PORT=11211
#USER=nobody
#MAXCONN=1024
#CACHESIZE=64
#OPTIONS=""

#找到

......
start () {
    echo -n $"Starting $prog: "
    # insure that /var/run/memcached has proper permissions
    chown $USER /var/run/memcached
    daemon memcached
......
#将daemon memcached更改为daemon /usr/local/memcached/bin/memcached

#创建并编辑配置文件

vim /etc/sysconfig/memcached

#写入配置信息

PORT=11211
USER=memcached
MAXCONN=1024
CACHESIZE=64
OPTIONS="-l 0.0.0.0,::1"

#设置权限

chown memcached.memcached /etc/sysconfig/memcached

#创建memcached进程文件目录,并设置权限

mkdir -p /var/run/memcached
chown memcached.memcached /var/run/memcached

#加入服务

chkconfig --add memcached

#开机启动

chkconfig memcached on

#启动

[root@jmsite init.d]# service memcached start
正在启动 memcached:                                       [确定]

#memcached服务管理

service memcached start 
service memcached stop 
service memcached restart
service memcached reload

5.使用telnet测试

telnet 127.0.0.1 11211

#如果提示-bash: telnet: command not found,则安装:yum install telnet telnet-server,没有则忽略该步骤

[root@jmsite init.d]# telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
set a 0 0 4
1234
STORED
get a
VALUE a 0 4
1234
END
quit
Connection closed by foreign host.
[root@jmsite init.d]#
