上篇剛裝完MySQL，現在我們再來裝Redis
1、大家先下載Redis安裝包
[root@izbp1g3d9v59h2hak283f2z ~]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz
--2019-12-30 14:24:03-- http://download.redis.io/releases/redis-5.0.5.tar.gz

我是直接通過網絡下載的，大家也可以現在Windows下下載好在通過工具上傳至Linux服務器
2、解壓
[root@izbp1g3d9v59h2hak283f2z ~]# tar -zxf redis-5.0.5.tar.gz
[root@izbp1g3d9v59h2hak283f2z ~]# ll
total 631756
-rw-r--r-- 1 root root 644930593 Oct 4 2018 mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
drwxrwxr-x 6 root root 4096 May 16 2019 redis-5.0.5
-rw-r--r-- 1 root root 1975750 May 16 2019 redis-5.0.5.tar.gz
3、移動
[root@izbp1g3d9v59h2hak283f2z ~]# mv redis-5.0.5 /usr/local/redis
[root@izbp1g3d9v59h2hak283f2z ~]# cd /usr/local/
[root@izbp1g3d9v59h2hak283f2z local]# ll
total 52

drwxr-xr-x. 6 root root 4096 Dec 23 16:19 share
drwxr-xr-x. 2 root root 4096 Nov 5 2016 src
[root@izbp1g3d9v59h2hak283f2z local]# cd redis
4、編譯
進入解壓後的Redis目錄，輸入 make 進行編譯
[root@izbp1g3d9v59h2hak283f2z redis]# make
cd src && make all
make[1]: Entering directory `/usr/local/redis/src'
CC Makefile.dep
make[1]: Leaving directory `/usr/local/redis/src'
make[1]: Entering directory `/usr/local/redis/src'
rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html Makefile.dep dict-benchmark
(cd ../deps && make distclean)
make[2]: Entering directory `/usr/local/redis/deps'
(cd hiredis && make clean) > /dev/null || true
(cd linenoise && make clean) > /dev/null || true
(cd lua && make clean) > /dev/null || true
(cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true
(rm -f .make-*)
make[2]: Leaving directory `/usr/local/redis/deps'
(rm -f .make-*)
echo STD=-std=c99 -pedantic -DREDIS_STATIC='' >> .make-settings
echo WARN=-Wall -W -Wno-missing-field-initializers >> .make-settings
echo OPT=-O2 >> .make-settings
echo MALLOC=jemalloc >> .make-settings
echo CFLAGS= >> .make-settings
echo LDFLAGS= >> .make-settings
編譯完成後，發現Redis目錄下會有對應的src、conf等文件夾
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/usr/local/redis/src'
[root@izbp1g3d9v59h2hak283f2z redis]# ll

drwxrwxr-x 11 root root 4096 May 16 2019 tests
drwxrwxr-x 8 root root 4096 May 16 2019 utils
5、安裝
進入src目錄，執行 make install 命令
[root@izbp1g3d9v59h2hak283f2z redis]# cd src
[root@izbp1g3d9v59h2hak283f2z src]# make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
[root@izbp1g3d9v59h2hak283f2z src]# ll
至此，Linux服務器上已成功安裝Redis
6、部署
爲了方便管理，將Redis文件中的conf配置文件和常用命令移動到統一文件中
1）、創建bin和etc文件
[root@izbp1g3d9v59h2hak283f2z redis]# mkdir etc
[root@izbp1g3d9v59h2hak283f2z redis]# mkdir bin
[root@izbp1g3d9v59h2hak283f2z redis]# ll
total 276
-rw-rw-r-- 1 root root 106874 May 16 2019 00-RELEASENOTES
drwxr-xr-x 2 root root 4096 Dec 30 14:41 bin
-rw-rw-r-- 1 root root 53 May 16 2019 BUGS
-rw-rw-r-- 1 root root 2381 May 16 2019 CONTRIBUTING
-rw-rw-r-- 1 root root 1487 May 16 2019 COPYING
drwxrwxr-x 6 root root 4096 Dec 30 14:36 deps
drwxr-xr-x 2 root root 4096 Dec 30 14:41 etc
-rw-rw-r-- 1 root root 11 May 16 2019 INSTALL
-rw-rw-r-- 1 root root 151 May 16 2019 Makefile
-rw-rw-r-- 1 root root 6888 May 16 2019 MANIFESTO
-rw-rw-r-- 1 root root 20555 May 16 2019 README.md
-rw-rw-r-- 1 root root 61797 May 16 2019 redis.conf
-rwxrwxr-x 1 root root 275 May 16 2019 runtest
-rwxrwxr-x 1 root root 280 May 16 2019 runtest-cluster
-rwxrwxr-x 1 root root 341 May 16 2019 runtest-moduleapi
-rwxrwxr-x 1 root root 281 May 16 2019 runtest-sentinel
-rw-rw-r-- 1 root root 9710 May 16 2019 sentinel.conf
drwxrwxr-x 3 root root 4096 Dec 30 14:39 src
drwxrwxr-x 11 root root 4096 May 16 2019 tests
drwxrwxr-x 8 root root 4096 May 16 2019 utils
2）、配置文件及常用命令移動
[root@izbp1g3d9v59h2hak283f2z redis]# mv redis.conf /usr/local/redis/etc/
[root@izbp1g3d9v59h2hak283f2z redis]# cd src
[root@izbp1g3d9v59h2hak283f2z src]# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server /usr/local/redis/bin/
[root@izbp1g3d9v59h2hak283f2z src]# cd ..
[root@izbp1g3d9v59h2hak283f2z redis]# cd etc/
[root@izbp1g3d9v59h2hak283f2z etc]# ll
total 64
-rw-rw-r-- 1 root root 61797 May 16 2019 redis.conf
[root@izbp1g3d9v59h2hak283f2z etc]# cd ..
[root@izbp1g3d9v59h2hak283f2z redis]# cd bin
[root@izbp1g3d9v59h2hak283f2z bin]# ll
total 32748
-rwxrwxr-x 1 root root 734 May 16 2019 mkreleasehdr.sh
-rwxr-xr-x 1 root root 4365912 Dec 30 14:37 redis-benchmark
-rwxr-xr-x 1 root root 8116448 Dec 30 14:37 redis-check-aof
-rwxr-xr-x 1 root root 8116448 Dec 30 14:37 redis-check-rdb
-rwxr-xr-x 1 root root 4806248 Dec 30 14:37 redis-cli
-rwxr-xr-x 1 root root 8116448 Dec 30 14:37 redis-server
7、啓動服務
進入 bin 目錄 以 etc 目錄下的配置文件作爲 Redis 服務的配置文件
[root@izbp1g3d9v59h2hak283f2z bin]# redis-server /usr/local/redis/etc/redis.conf
20597:C 30 Dec 2019 15:12:25.112 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

redis.conf 配置解析 （vim redis.conf）
daemonize：如需要在後臺運行，把該項的值改爲yes
pdifile：把pid文件放在/var/run/redis.pid，可以配置到其他地址
bind：指定redis只接收來自該IP的請求，如果不設置，那麼將處理所有請求，在生產環節中最好設置該項
(設置0.0.0.0 則改爲用iptables來控制訪問權限)
port：監聽端口，默認爲6379
timeout：設置客戶端連接時的超時時間，單位爲秒
loglevel：等級分爲4級，debug，revbose，notice和warning。生產環境下一般開啓notice
logfile：配置log文件地址，默認使用標準輸出，即打印在命令行終端的端口上
database：設置數據庫的個數，默認使用的數據庫是0
save：設置redis進行數據庫鏡像的頻率
rdbcompression：在進行鏡像備份時，是否進行壓縮
dbfilename：鏡像備份文件的文件名
dir：數據庫鏡像備份的文件放置的路徑
slaveof：設置該數據庫爲其他數據庫的從數據庫
masterauth：當主數據庫連接需要密碼驗證時，在這裏設定
requirepass：設置客戶端連接後進行任何其他指定前需要使用的密碼
maxclients：限制同時連接的客戶端數量
maxmemory：設置redis能夠使用的最大內存
appendonly：開啓appendonly模式後，redis會把每一次所接收到的寫操作都追加到appendonly.aof文件中，當redis重新啓動時，會從該文件恢復出之前的狀態
appendfsync：設置appendonly.aof文件進行同步的頻率
vm_enabled：是否開啓虛擬內存支持
vm_swap_file：設置虛擬內存的交換文件的路徑
vm_max_momery：設置開啓虛擬內存後，redis將使用的最大物理內存的大小，默認爲0
vm_page_size：設置虛擬內存頁的大小
vm_pages：設置交換文件的總的page數量
vm_max_thrrads：設置vm IO同時使用的線程數量
