ubuntu安裝redis

前端之家收集整理的这篇文章主要介绍了ubuntu安裝redis前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
安裝redis的時候需要make工具。ubuntu下沒有。需要參考以下安裝
 $ sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
 $ sudo apt-get update
Then,installing Ubuntu Make:

 $ sudo apt-get install ubuntu-make


來源:
https://wiki.ubuntu.com/ubuntu-make

之後在redis目錄執行make
還是失敗了。因為沒有安裝cc,繼續安裝:
sudo apt-get install gcc



再次make。又Failed了。
這次提示
#include [jemalloc] jemalloc.h
recipe for adlist.o Failed

執行以下操作:
Plz,Just try next step:
[root@localhost redis-2.6.10]# make distclean
[root@localhost redis-2.6.10]# cd deps; make; cd ..
[root@localhost redis-2.6.10]# cd src; make; cd ..


參考https://github.com/antirez/redis/issues/722

make install成功了。然後執行make test 又提示tcl沒安裝
sudo apt-get install tcl8.6-dev
sudo apt-get install tk8.6-dev


或者下载安装,参考:
http://blog.csdn.net/hybaym/article/details/9046565
wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz  
sudo tar xzvf tcl8.6.1-src.tar.gz  -C /usr/local/  
cd  /usr/local/tcl8.6.1/unix/  
sudo ./configure  
sudo make  
sudo make install   


安裝成功後,再執行make test。一大串test OK的結果就打印出來了。

后执行
whereis redis-cli
显示
redis-cli: /usr/local/bin/redis-cli

whereis redis-server
显示
redis-server: /usr/local/bin/redis-server


改成后台运行:
修改/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
daemonize no 改成 daemonize yes

后执行
/usr/local/bin/redis-server /home/mochong/redis/redis-3.0.3/redis.conf

查看
netstat -tlnp

显示,默认端口是6379
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN      47698/redis-server


执行
/usr/local/bin/redis-cli ping 

显示
pong


设置key/value
 redis-cli set mykey davidhuang

读取key
 redis-cli get mykey


参考:
http://www.PHP100.com/html/webkaifa/PHP/PHPyingyong/2011/0406/7873.html

配置参考:
http://blog.csdn.net/ithomer/article/details/9232891
redis 持久化写入rdb文件因为无权限写入失败

Background saving error
查看redis.conf的log文件地址
logfile ""
logfile /var/log/redis/redis-server.log

将该文件权限设置为755。

再查看
dir ./
dbfilename dump.rdb

dir 默认是在/usr/local/bin/dump.rdb
执行 /usr/local/bin/redis-cli
输入
CONFIG GET dir
CONFIG GET dbfilename

可以看到
1) "dir"
2) "/usr/local/bin"


1) "dbfilename"
2) "dump.rdb"


停止redis
redis-cli shutdown
出错: ERR Errors trying to SHUTDOWN. Check logs. 请注意:启动redis-server的时候一定要用sudo。 redis-cli也用sudo 否则可能没权限写入rdb。 安装redis gui https://github.com/ErikDubbelboer/PHPRedisAdmin http://192.168.3.111/PHPRedisAdmin/?view&s=0&d=0&key=davidhuang_%3Ajob%3A1 You may also want to copy includes/config.simple.inc.PHP to includes/config.inc.PHP and edit it with your specific redis configuration. Instead of using composer,you can also do a manual install using: git clone https://github.com/ErikDubbelboer/PHPRedisAdmin.git cd PHPRedisAdmin git clone https://github.com/nrk/predis.git vendor ---------------------------------- 我遇到过的坑。。 https://argcv.com/articles/3212.c 使用到mongo,redis等数据库的时候,往往会遇到这样一个坑。某mongo跑着跑着突然没了,某redis启动先给个warning,仔细一看log说最大文件打开数不够.. 1 2 3 # You requested maxclients of 10000 requiring at least 10032 max file descriptors. # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted. # Current maximum open files is 1024. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'. mongo官方也给教程说你修改下ulimit就可以。 但实际上,若该用户是普通用户 1 2 $ ulimit -n 65535 -bash: ulimit: open files: cannot modify limit: Operation not permitted 若你用root当然可以,但你真的想用root跑db么? 正确的打开方式其实应该是修改limit. 打开/etc/security/limits.conf,添加内容如下: /etc/security/limits.conf 1 2 your_user_name soft nofile 65535 your_user_name hard nofile 65535 或者若想要一加一个组 /etc/security/limits.conf 1 2 @your_group_name soft nofile 65535 @your_group_name hard nofile 65535 然后保存。 检查下/etc/pam.d/sudo或者/etc/pam.d/common-session-noninteractive,若没有发现如下这行信息,请自行加上 1 session required pam_limits.so 然后普通用户需要重新登录即可生效。若没有生效,这时普通用户应该也可以自行ulimit -n 65535了。 设置master slave 如果要将当前redis server改成slave。要修改redis.conf 将slaveof 的注释删除掉,改成 slaveof master_server_ip port 如果master server有密码,还要将masterauth删除注释 masterauth master_server_password 修改允许绑定的IP地址 bind master_server_ip 127.0.0.1 重启redis server redis-cli shutdown redis-server /xxx/redis-3.2.3/redis.conf
