linux 安装redis zookeeper

 

安装redis:

http://www.redis.cn/download.html

安装的前提条件：

需要安装gcc：yum install gcc-c++

wget http://download.redis.io/releases/redis-3.2.8.tar.gz
tar -zxvf redis-3.2.8.tar.gz
cd redis-3.2.8
#进行编译 make
make
#创建redis目录 /usr/local/redis
mkdir redis
#进入解压目录 
cd /usr/local/redis-3.2.9 
#安装目录
make install PREFIX=/usr/local/redis

如提示make无效需要安装gcc

安装完成

 复制配置文件redis.conf 到安装目录

 

修改配置文件 

daemonize yes 后台启动

 

requirepass redis 设置密码为redis

 

启动

[root@iZ28mgdqcyxZ bin]# ./redis-server redis.conf

 

安装zookeeper

安装之前要安装jdk 略

 wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz
#解压
 tar -zxvf zookeeper-3.3.6.tar.gz   
cd zookeeper-3.3.6/conf  
拷贝zoo_samle.cfg为zoo.cfg
cp  zoo_samle.cfg zoo.cfg
vi zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/mnt/disk/word/children/zookeeper-3.3.6/data
dataLogDir=/mnt/disk/word/children/zookeeper-3.3.6/logs
# the port at which the clients will connect
clientPort=2181

 

dataDir=/mnt/disk/word/children/zookeeper-3.3.6/data
dataLogDir=/mnt/disk/word/children/zookeeper-3.3.6/logs

　　注意：这里的data和logs是没有的，要自己创建 mkdir data ,mkdir logs

 

设置环境变量

vi /etc/profile

 

#zookeeper
export ZOOKEEPER_HOME=/mnt/disk/word/children/zookeeper-3.3.6
export PATH=$PATH:$ZOOKEEPER_HOME/bin

使环境变量生效 

source /etc/profile

 

启动，任何地方都可以启动

[root@iZ28mgdqcyxZ conf]# zkServer.sh start

 

设置redis & zookeeper 开机启动

vi /etc/rc.d/rc.local

#加载java环境变量 否则不能启动
export JAVA_HOME=/var/lib/jvm/jdk1.7.0_80
#启动zk
/mnt/disk/word/children/zookeeper-3.3.6/bin/zkServer.sh start

#启动redis
/mnt/disk/word/children/redis/bin/redis-server /mnt/disk/word/children/redis/bin/redis.conf

#在centos7中，/etc/rc.d/rc.local的权限被降低了，所以需要执行如下命令赋予其可执行权限
chmod +x /etc/rc.d/rc.local

 

centos 7防火墙：

0、开启防火墙：sudo systemctl start firewalld,service

1、关闭防火墙：sudo systemctl stop firewalld.service

2、关闭开机启动：sudo systemctl disable firewalld.service

3、开启开机启动：sudo systemctl enable firewalld.service

centos 6防火墙：

1、关闭防火墙：service iptables stop

2、开启防火墙：service iptables start

3、防火墙状态：service iptables status

完成
