This article briefly describes the steps to install a Redis server under Linux, with a brief introduction to server configuration, startup, and state detection. It also describes some of the problems encountered when installing Redis under 32-bit CentOS.

second, the installation of TCL
Install Tcl first, or Redis's make test will not pass. You can also install Redis and go back to installing TCL.
1. Download TCL installation package
To access http://sourceforge.net/projects/tcl/files/Tcl/, select the version you want to download. The author chooses the latest stable version of tcl8.6.1-src.tar.gz, size 8.5 MB. The author also uploaded a copy to csdn resources, if you suspect the foreign server speed slow, you can download this: tcl8.6.1 installation package.
2. Installation
Tar xvzf tcl8.6.1-src.tar.gz
CD tcl8.6.1/unix/
./configure
Make
Make Test
Make install
iii. installation of Redis
1. Download the Redis installation package
Visit Http://redis.io/download and choose the version that suits your scenario to download. The author chooses the latest stable version of Redis-2.8.10.tar.gz, which is 1 MB in size. The author also uploaded a copy to csdn resources, if you suspect the foreign server speed slow, you can download this: redis-2.8.10 installation package.
2. Lan Sharing
Most people's development environment is Windows, the author is no exception (of course, the Linux software development environment is also very good, such as the author has been under Linux for half a year Java Mobile development, the experience is wonderful).
So it's usually first downloaded to Windows local (if your speed is also available with wget), then FTP to Linux. Of course, you can also use the way of mount, for example, the author will download redis-2.8.10.tar.gz to the D:\defonds\work\20140610, first to share this folder, Win7 platform, right click Need file 20140610, properties, select "Share" page item, point "Share ..." button-and-File Sharing dialog box, click the "Share" button to confirm the share, and you will be prompted to share and display the Shared Item:
Local Network view:
3. Mounting
To create a new Redis directory:
Mkdir/home/defonds/redis
For example, the previous step to share the IP is 192.21.40.134, the machine user name defonds, password is defonds:
mount-o "Username=defonds,password=defonds"//192.21.40.134/20140610/home/defonds/redis
After the mount is successful, you can use DF to view the mount results, such as:
//192.21.40.134/20140610 133122588 72559176 60563412 55%/home/defonds/redis
4. Installation
Cd/home/defonds/redis
Tar xvzf redis-2.8.10.tar.gz
CD redis-2.8.10
Make
Mkdir/usr/local/redis
Make Prefix=/usr/local/redis Install
Mkdir/usr/local/redis/etc
mkdir/usr/local/redis/var/
CP redis.conf/usr/local/redis/etc/6379.conf
Note
If you encounter the following error while executing make (such as the author's 32-bit CentOS5.5):
zmalloc.o:in function ' zmalloc_used_memory ':
/home/defonds/redis/redis-2.8.10/src/zmalloc.c:223:undefined reference to ' __sync_add_and_fetch_4 '
Collect2:ld returned 1 exit status
MAKE[1]: * * * [redis-server] Error 1
MAKE[1]: Leaving directory '/HOME/DEFONDS/REDIS/REDIS-2.8.10/SRC '
Make: * * * [ALL] Error 2
Add the parameter cflags= "-march=i686" When you execute make:
Make cflags= "-march=i686"
Iv. Configuring Redis
Make a slight adjustment to the default/usr/local/redis/etc/6379.conf. Note that this configuration disables the auto-save feature, and the i/0 and memory consumption of save and BGSAVE are not negligible, and we allow the app or user to submit their own save.
Daemonize yespidfile/usr/local/redis/var/6379.pidlogfile/usr/local/redis/var/6379.logdatabases 2dbfilename 6379. Rdbdir/usr/local/redis/varappendfsync No
v. Operation and Testing
After installation and configuration, you can start Redis:
Cd/usr/local/redis
Nice-n -10 bin/redis-server etc/6379.conf
At this point, the service should be up and running. We can check these two ways:
ps aux | grep redis
BIN/REDIS-CLI INFO
The second way of printing results:

Finally, the Redis is detected. Redis-benchmark runs a set of REDIS commands and requires only GET and SET to test the host hardware and compilers:
Cd/usr/local/redis/bin
./redis-benchmark-t Get,set
Printing results:
#./redis-benchmark-t Get,set

Of course, you can also add-Q to refine the output:
./redis-benchmark-q-T Get,set
Printing results:
#./redis-benchmark-q-T Get,set

get:14245.01 Requests per second
