這篇文章主要講解了“ubuntu16.04怎么安裝redis主從集群”，文中的講解內(nèi)容簡(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“ubuntu16.04怎么安裝redis主從集群”吧！
前置環(huán)境
apt-get update apt install make apt install gcc gcc+ build-essential tcl
下載安裝
cd /app wget http://download.redis.io/releases/redis-5.0.5.tar.gz tar zxvf redis-5.0.5.tar.gz cd redis-5.0.5 make MALLOC=libc make test cd src && make install PREFIX=/usr/local/redis # 安裝成功后 root@redis-node1:/app/redis-5.0.5/src# make install PREFIX=/usr/local/redis Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install
make test出錯(cuò)
!!! WARNING The following tests failed:
*** [err]: PEXPIRE/PSETEX/PEXPIREAT can set sub-second expires in tests/unit/expire.tcl
Expected 'somevalue {}' to equal or match '{} {}'
Cleanup: may take some time... OK
Makefile:262: recipe for target 'test' failed
make[1]: *** [test] Error 1
make[1]: Leaving directory '/app/redis-5.0.5/src'
Makefile:6: recipe for target 'test' failed
make: *** [test] Error 2
某些操作性需要更多的時(shí)間，修改tests/unit/expire.tcl
tags {"slow"} {
test {EXPIRE - After 2.1 seconds the key should no longer be here} {
after 21000 # 這里加個(gè)0
list [r get x] [r exists x]
} {{} 0}
}
test {EXPIRE - write on expire should work} {
r del x
r lpush x foo
r expire x 10000 # 這里加個(gè)0
r lpush x bar
r lrange x 0 -1
} {bar foo}
# 如下輸出安裝成功
\o/ All tests passed without errors!
Cleanup: may take some time... OK
make[1]: Leaving directory '/app/redis-5.0.5/src'配置
