liunx系统下安装redis

Posted 2020-10-28 Azjs丶V1

1.下载redis安装包（我这里用的是redis-3.2.1.tar.gz）

2.将redis安装包放到/tmp 目录下

3.解压redis安装包 tar xf redis-3.2.1.tar.gz

4.切换至解压目录 cd redis-3.2.1

5.编译和安装 （依次执行以下命令）

mkdir –p /opt/redis

make PREFIX=/opt/redis USE_TCMALLOC=yes FORCE_LIBC_MALLOC=yes install

make MALLOC=libc

再次执行

make PREFIX=/opt/redis USE_TCMALLOC=yes FORCE_LIBC_MALLOC=yes install

6.创建配置文件和文件夹

mkdir -p /opt/redis/etc

mkdir -p /opt/redis/run

mkdir -p /opt/redis/data/6379

mkdir -p /opt/redis/log

cp redis的解压路径/redis.conf /opt/redis/etc/redis.conf

cp /opt/redis/etc/redis.conf /opt/redis/etc/redis_6379.conf

7.修改配置文件

vim /opt/redis/etc/redis_6379.conf
-------------------修改内容--------------------
daemonize yes
pidfile /opt/redis/run/redis_6379.pid
dir /opt/redis/data/6379
logfile /opt/redis/log/redis_6379.log

vim之后 设置 密码 /requirepass 设置 redis6379 :wq保存退出

8.创建服务脚本

cp 【已撰写好】/redis /etc/init.d/redis

(redis要覆盖)设置密码修改

vim /etc/init.d/redis

以下是服务脚本（redis）

 1 #!/bin/sh
 2 PATH="/opt/redis/bin:PATH"
 3 EXEC="/opt/redis/bin/redis-server"
 4 CLIEXEC="/opt/redis/bin/redis-cli"
 5 PIDFILE="/opt/redis/run/redis_6379.pid"
 6 CONF="/opt/redis/etc/redis_6379.conf"
 7 REDISPORT="6379"
 8 
 9 case "$1" in
10     start)
11         if [ -f $PIDFILE ]
12         then
13             echo "$PIDFILE exists,process is already running or crashed"
14         else
15             echo "Starting Redis server..."
16             $EXEC $CONF
17         fi
18         ;;
19     stop)
20         if [ ! -f $PIDFILE ]
21         then
22             echo "$PIDFILE does not exist,process is not running."
23         else
24             PID=$(/bin/cat $PIDFILE)
25             echo "Stopping..."
26             $CLIEXEC -p $REDISPORT shutdown
27             while [ -x /proc/${PID} ]
28             do
29                 echo "Waiting for Redis to shutdown..."
30                 /bin/sleep 1
31             done
32             echo "Redis stopped."
33         fi
34         ;;
35     *)
36         echo "Usage:$0 {start|stop}" >&2
37         exit 1
38         ;;
39     esac

 

chmod +x /etc/init.d/redis

9.修改sysctl.conf

vim /etc/sysctl.conf
-------------------修改内容 最后添加--------------------
vm.overcommit_memory = 1

10.生效内核参数 sysctl –p

启动服务 /etc/init.d/redis start

11.测试服务是否启动
ps aux | grep redis
