Centos6.5 install Redis

Centos6.5 install Redis

After a long time, we will find that there is no difference in the next step between linux software and Windows. Even more fun. Just give me a line of command. Let's go! A pile of screens flashed through. It's amazing to be a layman. Hahaha, there is actually no technical content. Just a few lines of commands.

# Install redis in linux to obtain [root @ weixinht src] # wget http://download.redis.io/redis-stable.tar.gz#decompress the package and put it in the directory specified by the-C parameter in/usr/local. # Tar-zxvf redis-stable.tar.gz-C/usr/local/# Switch to the decompressed directory redis-stable is the decompressed file name [root @ weixinht ~] # Cd/usr/local/redis-stable/# compile and install [root @ weixinht ~] # Make # After completion, you will be prompted to go To the src directory and execute make test. [root @ weixinht ~] # Cd/usr/local/redis-stable/src/[root @ weixinht ~] # Make test # Here I will report an error. If tcl is not installed, it will certainly not report my feelings, but it will be of great help to beginners. [root @ weixinht ~] # Yum install-y tcl prompt success no errors or errors, and do not be afraid of Baidu Google's Solutions

Note: After make is successful, some executable files will be added to the src directory: redis-server, redis-cli, and so on. The key part is the following boot script snippet. Note the following paths: "'redis_path ="/usr/local/bin/redis-server "redis_conf ="/etc/redis/redis_m.conf "redis_pid ="/var/redis/run/ redis_m.pid"

These directories are created to store the configuration file mkdir/etc/redismkdir/var/redis/logmkdir/var/redis/runmkdir/var/redis/redis_m.

Copy the configuration file

[Root @ weixinht redis-stable] # pwd/usr/local/redis-stable # Find the configuration file template in the redis root directory and copy it to the following location. [Root @ weixinht redis-stable] # cp redis. conf/etc/redis/redis_m.conf [root @ weixinht redis-stable] # cd src [root @ weixinht src] # cp redis-server/usr/local/bin/[root @ weixinht src] # cp redis-cli/usr/local/bin/

Vim Modify/etc/redis/redis_m.conf

daemonize yespidfile /var/redis/run/redis_m.pidlogfile /var/redis/log/redis_m.logdir /var/redis/redis_m

Finally, run the redis specified configuration file: [root @ weixinht src] # the corresponding redis-server/etc/redis/redis_m.conf file will be generated

Redis boot start redis boot script note that the configuration file path is correct

Vim/etc/init. d/redis # create a file and add the content #! /Bin/sh # chkconfig: 2345 90 10 # description: Redis is a persistent key-value database # redis Startup script for redis processes # processname: redis # note the following paths: redis_path = "/usr/local/bin/redis-server" redis_conf = "/etc/redis/redis_m.conf" redis_pid = "/var/redis/run/ redis_m.pid "# Source function library .. /etc/rc. d/init. d/functions [-x $ redis_path] | exit 0 RETVAL = 0 prog = "redis" # Start daemons. start () {if [-E $ redis_pid-! -Z $ redis_pid]; thenecho $ prog "already running ....
