官網：Redis - The Real-time Data Platform
Linux安裝Redis：
1.安裝gcc
安裝gcc yum -y install gcc tcl 如果出現Complete 表示成功
查看gcc版本 gcc -v
2.升級gcc
升級到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命令啓用只是臨時的，退出shell或重啓就會恢復原系統gcc版本。 如果要長期使用gcc 9.3的話： 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.安裝Redis
載redis安裝包 wget http://download.redis.io/releases/redis-6.2.5.tar.gz
如果出現了command not found 則要安裝wget
yum install -y wget
解壓安裝包 [root@node01 modules]# tar -zxvf redis-6.2.5.tar.gz 進入安裝包 [root@node01 modules]# cd redis-6.2.5/ 編譯和安裝 make && make test && make install
編譯出錯時，清出編譯生成的文件
make distclean
卸載
make uninstall
4.配置Redis
將服務端腳本和客戶端腳本移動到新建的文件夾下面
在安裝目錄下創建一個 bin 目錄 [root@node01 redis-6.2.5]# mkdir bin [root@node01 redis-6.2.5]# cd src/
將 redis-server 和 redis-cli 移動到 bin 目錄中 [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
將 redis 的配置文件 redis.conf 移動到 bin 目錄下 [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，修改的內容在下面 [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
設置可以訪問redis服務的IP，0，0,0，表示可以遠程訪問 bind 0.0.0.0 設置redis的訪問端口 port 6379 設置訪問redis的密碼 requirepass 123456 設置 redis-server 以守護線程方式啓動 daemonize yes
啓動redis
啓動 redis 服務, 後面加 & 參數後臺表示啓動 $REDIS_HOME/bin/redis-server redis.conf & 查看 redis 進程是否啓動 [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 啓動 redis 的客戶端 $REDIS_HOME/bin/redis-cli 登錄 redis auth [yourpassword]
開啓自啓動
創建開機自啓動腳本的文件
vim /etc/init.d/redis
編寫開機自啓動的腳本， 注意替換自己的redis的啓動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..." # 啓動 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 # 帶有密碼的redis關閉方式： 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
設置開機自啓動
爲redis開機啓動腳本賦予執行權限 chmod +x /etc/init.d/redis 開啓redis服務 systemctl start redis 查看redis的狀態 systemctl status redis 停止redis服務 systemctl stop redis 查看redis服務的狀態 systemctl status redis 設置redis開機自啓動 systemctl enable redis 設置禁止redis開機自啓動 systemctl disable redis
NET6中使用ServiceStack.Redis
安裝包：ServiceStack.Redis
1.配置文件信息
/// <summary> /// Redis配置文件信息 /// </summary> public class RedisConfigurationInfo { /// <summary> /// 可寫的Redis鏈接地址 /// format:ip1,ip2 /// 默認6379端口 /// </summary> public string WriteServerList = "127.0.0.1:6379"; /// <summary> /// 可讀的Redis鏈接地址 /// format:ip1,ip2 /// </summary> public string ReadServerList = "127.0.0.1:6379"; /// <summary> /// 最大寫鏈接數 /// </summary> public int MaxWritePoolSize = 60; /// <summary> /// 最大讀鏈接數 /// </summary> public int MaxReadPoolSize = 60; /// <summary> /// 本地緩存到期時間，單位:秒 /// </summary> public int LocalCacheTime = 180; /// <summary> /// 自動重啓 /// </summary> public bool AutoStart = true; /// <summary> /// 是否記錄日誌,該設置僅用於排查redis運行時出現的問題, /// 如redis工作正常,請關閉該項 /// </summary> public bool RecordeLog = false; }
2.創建Redis鏈接
/// <summary> /// 創建Redis鏈接 /// </summary> public class RedisManager { /// <summary> /// redis配置文件信息 /// </summary> private static RedisConfigurationInfo RedisConfigInfo = new RedisConfigurationInfo(); /// <summary> /// Redis客戶端池化管理 /// </summary> private static PooledRedisClientManager prcManager; /// <summary> /// 靜態構造方法，初始化鏈接池管理對象 /// </summary> static RedisManager() { CreateManager(); } /// <summary> /// 創建鏈接池管理對象 /// </summary> private static void CreateManager() { string[] WriteServerConStr = RedisConfigInfo.WriteServerList.Split(','); string[] ReadServerConStr = RedisConfigInfo.ReadServerList.Split(','); prcManager = new PooledRedisClientManager(ReadServerConStr, WriteServerConStr, new RedisClientManagerConfig { MaxWritePoolSize = RedisConfigInfo.MaxWritePoolSize, MaxReadPoolSize = RedisConfigInfo.MaxReadPoolSize, AutoStart = RedisConfigInfo.AutoStart, }); } /// <summary> /// 客戶端緩存操作對象 /// </summary> public static IRedisClient GetClient() { return prcManager.GetClient(); } }
3.實現Redis內操作方法
