安装redis-3.2.10单节点

前段时间安装好的redis，今天用脚本安装的时候突然出现版本异常的问题，所以更新一篇为大家提供参考

本次安装在CentOS6.5，采用的redis-3.2.10，最新的redis-4.0.1安装同样适用，不过由于4.0.1版本的redis改动较大，大家自己选择即可。,

1.基础环境配置，上传安装包

# 下载地址：http://download.redis.io/releases/redis-3.2.10.tar.gz

useradd redis -s /sbin/nologin -M
mkdir -p /server/tools/
cd /server/tools/

2.安装redis，配置开机自启动

# 解压，编译安装

tar -zxf redis-3.2..tar.gz
cd redis-3.2.
make PREFIX=/usr/local/redis
make PREFIX=/usr/local/redis install

# 配置环境变量，便于命令工具的调用访问

export PATH=/usr/local/redis/bin/:$PATH
echo 'export PATH=/usr/local/redis/bin:$PATH' >> /etc/profile
echo $PATH

# 手动创建标准目录结构，操作规范化

mkdir -p /usr/local/redis/{conf,data,logs}
/bin/cp /server/tools/redis-3.2./redis.conf /usr/local/redis/conf/redis.conf.ori
tree /usr/local/redis

# 创建修改配置文件

cd /usr/local/redis/conf
egrep -v "^#|^$" redis.conf.ori>redis.conf
cat redis.conf

# 默认生效的配置如下：

bind 127.0.0.1

# 修改配置文件

vim redis.conf

# 确认以下必要的配置，修改完毕后的配置文件可以作为模板，用于创建新的redis实例

bind 0.0.0.0
port 6379
daemonize yes
pidfile /usr/local/redis/logs/redis.pid
logfile /usr/local/redis/logs/redis.log
dir /usr/local/redis/data
dbfilename redis.rdb

# 内核参数调优（临时）

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo  > /proc/sys/net/core/somaxconn
cat /sys/kernel/mm/transparent_hugepage/enabled
cat /proc/sys/net/core/somaxconn
echo "vm.overcommit_memory = 1" >>/etc/sysctl.conf
sysctl -p

# 启动redis，并查看redis启动状态

/usr/local/redis/bin/redis-server /usr/local/redis/conf/redis.conf
ps -ef |grep redis
netstat -anptl |grep redis

[root@redis-server conf]# cat /usr/local/redis/logs/redis.log

:M  Sep ::39.255 # Server started, Redis version 3.2.
:M  Sep ::39.255 * The server is now ready to accept connections on port 

# 连接redis，进行测试

[root@redis-server conf]# /usr/local/redis/bin/redis-cli -p
127.0.0.1:> set a
OK
127.0.0.1:> set b
OK
127.0.0.1:> set c
OK
127.0.0.1:> get a
""
127.0.0.1:> get b
""
127.0.0.1:> get c
""
127.0.0.1:> exit
[root@redis-server conf]# 

# 安全关闭redis-server

/usr/local/redis/bin/redis-cli shutdown

# 另外，需要设置一下内核参数保证下次重启不会出错

echo " ">> /etc/rc.local
echo "# redis by zhaoshuai in $(date +%F)" >> /etc/rc.local
echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local
echo "echo 511 > /proc/sys/net/core/somaxconn" >>/etc/rc.local
tail - /etc/rc.local

# 至此，redis-server就安装完成了。

3.创建新的redis实例（端口）

mkdir -p /usr/loca/redis/
cd /usr/local/redis/conf
cp redis.conf /usr/loca/redis//.conf
cd /usr/local/redis/6380/

# 编辑配置文件，

vim .conf

# 修改为以下内容：

bind 0.0.0.0
daemonize yes
pidfile /usr/local/redis//pid-.pid
logfile /usr/local/redis//log-.log
dir /usr/local/redis/
dbfilename .rdb
......

# 启动redis新实例，如果需要可以设置开机自启动

[root@redis-server ]# /usr/local/redis/bin/redis-server /usr/local/redis/6380/.conf 

[root@redis-server 6380]# echo "/usr/local/redis/bin/redis-server /usr/local/redis/6380/6380.conf" >>/etc/rc.local 

4.另附一个redis启动管理脚本，方便大家学习使用

#!/bin/sh
#
# chkconfig:
# description: this script can manager the redis-server daemon
#              Redis is a persistent key-value database
# exec:        /usr/local/redis/bin/redis-server
# config:      /usr/local/redis/conf/redis.conf
# pidfile:     /usr/local/redis/logs/redis.pid
# datafile:    /usr/local/redis/data/redis.rdb  

redis="/usr/local/redis/bin/redis-server"
REDIS_CONF_FILE="/usr/local/redis/conf/redis.conf"
prog=$(basename $redis)
lockfile=/var/lock/subsys/redis

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 

start() {
    [ -x $redis ] || exit
    [ -f $REDIS_CONF_FILE ] || exit
    echo -n $"Starting $prog: "
    daemon $redis $REDIS_CONF_FILE
    retval=$?
    echo
    [ $retval -eq  ] && touch $lockfile
    return $retval
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq  ] && rm -f $lockfile
    return $retval
}
restart() {
    stop
    start
}
reload() {
    echo -n $"Reloading $prog: "
    killproc $redis -HUP
    RETVAL=$?
    echo
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null >&
}
case "$1" in
    start)
        rh_status_q && exit
        $
        ;;
    stop)
        rh_status_q || exit
        $
        ;;
    restart)
        $
        ;;
    reload)
        rh_status_q || exit
        $
        ;;
    status)
        rh_status
        ;;
    *)
        echo $"Usage: $0 {start|stop|restart|reload|status}"
        exit
esac

# 完毕，呵呵呵
