Redis Install, configure, start/stop in Linux environment __linux

Installation Environment: Ubuntu 16.04.2

Install gcc:apt install gcc/yum-y install GCC

Download Redis extract file: wget http://download.redis.io/redis-stable.tar.gz

Decompression: Tar xzvf redis-stable.tar.gz
Switch to unzip directory: CD redis-stable
Compiling: Make

Problems that may occur with the compilation process:

1) zmalloc.h:50:31:fatal error:jemalloc/jemalloc.h:no such file or directory

The reason is that Jemalloc overloads the malloc and free functions of ANSI C under Linux. Workaround: Add parameters when make.

WORKAROUND: Recompile with make MALLOC=LIBC

2 The compilation completes, will prompt hint:it ' s a good idea to the run ' make test ';) if compiles the checksum with makes test, may report the following error:

CD src && make Test
make[1]: Entering directory '/OPT/REDIS-STABLE/SRC ' your
need TCL 8.5 or newer in order To run the Redis test
makefile:225:recipe for target ' test ' failed
make[1]: * * * [Test] Error 1
make[1]: Leav ing directory '/opt/redis-stable/src '
makefile:6: Recipe for target ' test ' failed make
: * * * [Test] Error 2

Solution: Apt Install Tcl/yum install TCL

After the installation is successful, use make test again for testing, which may be longer.

After successful display: \o/all Tests passed without errors!

3 After testing OK, use make install to install

Make install copies Redis executable files to the/usr/local/bin directory, and subsequent boot Redis can directly enter the executable file name.

5) Start Redis

5.1) Direct boot, enter redis-server; The default port number is 6379, you can customize the port number Redis-server--port 6380

5.2 Start Redis (production environment recommended) through initialization script.

First, switch directories to the front of the Redis decompression directory, which has a utils directory, go in to find a Redis_init_script initialization script file

#!/bin/sh # Simple Redis INIT.D script conceived to work on Linux systems # as it does the use of The/proc filesystem. redisport=6379 Exec=/usr/local/bin/redis-server cliexec=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${  Redisport}.pid conf= "/etc/redis/${redisport}.conf" case "$" in     start)         IF [f $PIDFILE]         then                 echo "$PIDFILE exists  , process is already running or crashed "        else                 echo "Starting Redis server ..."                 $EXEC $CONF    
    fi        ;      stop)         IF [!-F $PIDFILE]         then                 echo "$PIDFILE does not exist, process isn't running"       &NBsp  else                 pid=$ (cat $PIDFILE)             
    echo "stopping ..."                 $CLIEXEC-p $REDISPORT shutdown                 while [-x/proc/${pid}]           &NBS P      do                     echo ' Waiting for Redis to shutdown ... "                    Sleep 1           &NB Sp     done                 echo "Redis stopped"       &NBSP ;
Fi        ;;      *)         echo "Please use Start or stop as" argument "       
;; Esac

5.1.1) to configure initialization scripts. First copy the initialization script into the/ETC/INIT.D directory, renaming the file name as the Redis_ port number (CP redis_init_script/etc/init.d/redis_6379), Modifying the Redisport value of line sixth of the script is the same port number.

5.1.2) to create the desired folder.

/etc/redis the configuration file used to store Redis

The/var/redis/port number is used to hold the Redis persisted file

5.1.3) To modify the configuration file. First copy the Redis.conf profile template under the unpack package to the/etc/redis directory, name the port number (such as CP redis.conf/etc/redis/6379.conf), and then edit some of the parameters. (Note: After entering VI, press/, and then input string, carriage return, press N or n is to search backwards and forwards the string)

Daemonize Yes enables Redis to run in daemon mode

Pidfile/var/run/redis_6379.pid set the Redis PID file location

Port 6379 Set the port number for Redis listening

dir/var/redis/Port Number Set persistent file storage location

5.1.4) Start Redis.

/etc/init.d/redis_ Port number Start

If you want to automatically start the system, enter the command: sudo update-rc.d redis_ port number Defaults

5.1.4) Stop Redis. Forced termination of the REDIS process may result in data loss, in the correct manner: Redis-cli SHUTDOWN, and PID with the kill Redis process can also end normally Redis
