04_NET中使用Redis(ServiceStack.Redis)和Linux中安装Redis(docker安装和普通安装)
官网：Redis - The Real-time Data Platform
Linux安装Redis：
1.安装gcc
安装gcc yum -y install gcc tcl 如果出现Complete 表示成功
查看gcc版本 gcc -v
2.升级gcc
升级到gcc 9.3： yum -y install centos-release-scl yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash 需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。 如果要长期使用gcc 9.3的话： echo -e "\nsource /opt/rh/devtoolset-9/enable" >>/etc/profile 查看gcc版本 [root@node01 ~]# gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/lto-wrapper Target: x86_64-redhat-linux Configured with: ../configure --enable-bootstrap --enable-languages=c,c++,fortran,lto --prefix=/opt/rh/devtoolset-9/root/usr --mandir=/opt/rh/devtoolset-9/root/usr/share/man --infodir=/opt/rh/devtoolset-9/root/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --with-default-libstdcxx-abi=gcc4-compatible --enable-plugin --enable-initfini-array --with-isl=/builddir/build/BUILD/gcc-9.3.1-20200408/obj-x86_64-redhat-linux/isl-install --disable-libmpx --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux Thread model: posix gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC)
3.安装Redis
载redis安装包 wget http://download.redis.io/releases/redis-6.2.5.tar.gz
如果出现了command not found 则要安装wget
yum install -y wget
解压安装包 [root@node01 modules]# tar -zxvf redis-6.2.5.tar.gz 进入安装包 [root@node01 modules]# cd redis-6.2.5/ 编译和安装 make && make test && make install
编译出错时，清出编译生成的文件
make distclean
卸载
make uninstall
4.配置Redis
将服务端脚本和客户端脚本移动到新建的文件夹下面
在安装目录下创建一个 bin 目录 [root@node01 redis-6.2.5]# mkdir bin [root@node01 redis-6.2.5]# cd src/
将 redis-server 和 redis-cli 移动到 bin 目录中 [root@node01 src]# cp redis-server ../bin/ [root@node01 src]# cp redis-cli ../bin/ [root@node01 src]# cd .. [root@node01 redis-6.2.5]# ls 00-RELEASENOTES BUGS CONTRIBUTING deps Makefile README.md runtest runtest-moduleapi sentinel.conf tests utils bin CONDUCT COPYING INSTALL MANIFESTO redis.conf runtest-cluster runtest-sentinel src TLS.md
将 redis 的配置文件 redis.conf 移动到 bin 目录下 [root@node01 redis-6.2.5]# cp redis.conf bin/ [root@node01 redis-6.2.5]# cd bin/ [root@node01 bin]# ls redis-cli redis.conf redis-server 修改配置文件，修改的内容在下面 [root@node01 bin]# vim redis.conf [root@node01 bin]# ./redis-server redis.conf [root@node01 bin]# ./redis-cli 127.0.0.1:6379> set test hello OK 127.0.0.1:6379> get test "hello"
配置redis.conf 文件
设置可以访问redis服务的IP，0，0,0，表示可以远程访问 bind 0.0.0.0 设置redis的访问端口 port 6379 设置访问redis的密码 requirepass 123456 设置 redis-server 以守护线程方式启动 daemonize yes
启动redis
启动 redis 服务, 后面加 & 参数后台表示启动 $REDIS_HOME/bin/redis-server redis.conf & 查看 redis 进程是否启动 [root@localhost bin]# ps -ef | grep redis root 85823 62546 0 23:54 pts/1 00:00:00 ./redis-server 0.0.0.0:6379 root 85839 83082 0 23:55 pts/2 00:00:00 grep --color=auto redis 启动 redis 的客户端 $REDIS_HOME/bin/redis-cli 登录 redis auth [yourpassword]
开启自启动
创建开机自启动脚本的文件
vim /etc/init.d/redis
编写开机自启动的脚本， 注意替换自己的redis的启动命令的位置以及配置文件的位置
case "$1" in start) if [ -f $PIDFILE ] then echo "$PIDFILE exists, process is already running or crashed" else echo "Starting Redis server..." # 启动 Redis $EXEC $CONF fi ;; stop) if [ ! -f $PIDFILE ] then echo "$PIDFILE does not exist, process is not running" else PID=$(cat $PIDFILE) echo "Stopping ..." # $CLIEXEC -p $REDISPORT shutdown # 带有密码的redis关闭方式： redis-cli -a 123456 shutdown $CLIEXEC -a 123456 shutdown while [ -x /proc/${PID} ] do echo "Waiting for Redis to shutdown ..." sleep 1 done echo "Redis stopped" fi ;; status) if [ ! -f $PIDFILE ] then echo 'Redis is not running' else PID=$(cat $PIDFILE) if [ ! -x /proc/${PID} ] then echo 'Redis is not running' else echo "Redis is running ($PID)" fi fi ;; restart) $0 stop $0 start ;; *) echo "Please use start, stop, restart or status as first argument" ;; esac
设置开机自启动
为redis开机启动脚本赋予执行权限 chmod +x /etc/init.d/redis 开启redis服务 systemctl start redis 查看redis的状态 systemctl status redis 停止redis服务 systemctl stop redis 查看redis服务的状态 systemctl status redis 设置redis开机自启动 systemctl enable redis 设置禁止redis开机自启动 systemctl disable redis

Docker安装Redis
最新版
docker pull redis
指定版
docker pull redis:xxx
查看镜像
docker images
创建容器并启动运行
docker run \ --restart=always \ --log-opt max-size=100m \ --log-opt max-file=2 \ -p 6379:6379 \ --name redis \ -v /home/redis/myredis/myredis.conf:/etc/redis/redis.conf \ -v /home/redis/myredis/data:/data \ -d redis redis-server /etc/redis/redis.conf \ --appendonly yes \ --requirepass 123456
--restart=always : redis启动方式：开机启动 --log-opt ： 日志配置 -p 6379:6379 ： 主机与容器映射端口 --name ： 容器名称，多个不要重复 -v ： 挂载地址，主机地址：容器地址 -d redis redis-server /etc/redis/redis.conf ： Redis启动时使用redis.conf 配置文件 --appendonly yes ： 开启持久化 --requirepass ： 密码
查看容器
docker ps
关闭容器
docker stop redis
启动容器
docker start redis
NET6中使用ServiceStack.Redis
安装包：ServiceStack.Redis
1.配置文件信息
/// <summary> /// Redis配置文件信息 /// </summary> public class RedisConfigurationInfo { /// <summary> /// 可写的Redis链接地址 /// format:ip1,ip2 /// 默认6379端口 /// </summary> public string WriteServerList = "127.0.0.1:6379"; /// <summary> /// 可读的Redis链接地址 /// format:ip1,ip2 /// </summary> public string ReadServerList = "127.0.0.1:6379"; /// <summary> /// 最大写链接数 /// </summary> public int MaxWritePoolSize = 60; /// <summary> /// 最大读链接数 /// </summary> public int MaxReadPoolSize = 60; /// <summary> /// 本地缓存到期时间，单位:秒 /// </summary> public int LocalCacheTime = 180; /// <summary> /// 自动重启 /// </summary> public bool AutoStart = true; /// <summary> /// 是否记录日志,该设置仅用于排查redis运行时出现的问题, /// 如redis工作正常,请关闭该项 /// </summary> public bool RecordeLog = false; }
