安裝Redis

1、解壓Redis包

> tar -zxvf redis-4.0.2.tar.gz

2、切換到Redis解壓目錄

> cd redis-4.0.2

3、編譯Redis

> make

如報錯按以下錯誤解決。

make: cc：命令未找到

make: *** [adlist.o] 錯誤 127

> yum install gcc

collect2: ld returned 1 exit status

make[1]: *** [redis-server] Error 1

make[1]: Leaving directory `/usr/local/redis/src'

make: *** [all] Error 2

> vi src/.make-settings，修改OPT=-O2 -march=x86-64

4、編譯測試

> make test

報錯解決。

make[1]: Entering directory /home/test/redis-4.0.2/src'<br/>CC Makefile.dep<br/>make[1]: Leaving directory/home/test/redis-4.0.2/src'
make[1]: Entering directory /home/test/redis-4.0.2/src'<br/>You need tcl 8.5 or newer in order to run the Redis test<br/>make[1]: *** [test] Error 1<br/>make[1]: Leaving directory/home/test/redis-4.0.2/src'

> wget http://downloads.sourceforge.net/tcl/tcl8.6.7-src.tar.gz> tar -zxvf tcl8.6.7-src.tar.gz> cd tcl8.6.7/unix/> ./configure> make> make install

5、安裝

切換到redis目錄執行安裝。

> make install
