【redis】Redis绿色部署

Linux 下安装

下载地址：http://redis.io/download，下载最新稳定版本。

$ wget http://download.redis.io/releases/redis-5.0.5.tar.gz
$ tar xzf redis-5.0.5.tar.gz
$ cd redis-5.0.5
$ make

make完后 redis-5.0.5目录下会出现编译后的redis服务程序redis-server，还有用于测试的客户端程序redis-cli，两个程序位于安装目录 src 目录下：

下面启动redis服务。

$ cd src
$ ./redis-server

注意这种方式启动redis 使用的是默认配置。也可以通过启动参数告诉redis使用指定配置文件使用下面命令启动。

$ cd src
$ ./redis-server ../redis.conf

redis.conf 是一个默认的配置文件。我们可以根据需要使用自己的配置文件。

启动redis服务进程后，就可以使用测试客户端程序redis-cli和redis服务交互了。 比如：

$ cd src
$ ./redis-cli
redis> set foo bar
OK
redis> get foo
"bar"

redis绿色安装

安装到指定目录

# 安装到 /usr/local/redis

installpath=/usr/local/redis
mkdir -p $installpath
cd redis-5.0.5
make MALLOC=libc
make PREFIX=$installpath install
\cp -f redis.conf $installpath

功能测试（耗时较长，非必须执行）

在安装成功之后，可以运行测试，确认Redis的功能是否正常
[root@localhost ~]# make test

出现报错：
hadoop@stormspark:~/workspace/redis2.6.13/src$ make test
You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] Error 1

解决方式
yum install -y tcl

重新执行测试
[root@localhost ~]# make test

......

\o/ All tests passed without errors!

Cleanup: may take some time... OK

修改配置文件

installpath=/usr/local/redis
sed -i '/^bind/c#bind 127.0.0.1' "$installpath/redis.conf"
sed -i '/^protected-mode/cprotected-mode no' "$installpath/redis.conf"
sed -i '/^logfile/clogfile "'$installpath'/redis.log"' "$installpath/redis.conf"
sed -i '/^pidfile/cpidfile "'$installpath'/redis.pid"' "$installpath/redis.conf"

编写Redis启停脚本

[root@localhost ~]# vi /usr/local/redis/redis.sh

#!/bin/sh
#Configurations injected by install_server below....

EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/usr/local/redis/redis.pid
CONF="/usr/local/redis/redis.conf"
REDISPORT="6379"

        $0 start
        ;;

        echo "Please use start, stop, restart or status as first argument"
        ;;
esac

[root@localhost ~]# chmod u+x /usr/local/redis/redis.sh

使用redis 用户以systemd 服务启动

编写systemd服务
[root@localhost ~]# vi /usr/local/redis/redis.service

-----------------------------------------
[Unit]
Description=redis server

[Service]
User=redis
WorkingDirectory=/usr/local/redis
ExecStart=/usr/bin/sh redis.sh start
ExecStop=/usr/bin/sh redis.sh stop

[Install]
WantedBy=multi-user.target
-----------------------------------------
[Unit]
Description=redis server

[Service]
User=redis
WorkingDirectory=/usr/local/redis
ExecStart=/usr/local/redis/bin/redis-server redis.conf

[Install]
WantedBy=multi-user.target
-----------------------------------------

放置服务文件
[root@localhost ~]# \cp -f /usr/local/redis/redis.service /usr/lib/systemd/system/redis.service

创建redis用户
[root@localhost ~]# useradd -r -s /bin/false redis

修改文件所属
[root@localhost ~]# chown -R redis.redis /usr/local/redis

启动并设置开机自启
[root@localhost ~]# systemctl start redis
[root@localhost ~]# systemctl enable redis

防火墙配置

sudo firewall-cmd --permanent --add-port=6379/tcp
sudo firewall-cmd --reload
