Installing Redis and PHP Redis extensions under Linux

1. Installing Redis and PHP Redis extensions under Linux

2. Environment configuration: centos6.0 nginx/1.0.0 php/5.3.8 mysql/5.5.17

3. Step one, download Redis

4. can go to http://redis.io/to download the latest version

5. I'm using a Redis 2.8.11.

6. Go to the Software installation package storage directory: cd/var/install/software/

7. wget http://download.redis.io/redis-stable.tar.gz

2. Step two, compile the source program

4. Tar xvzf redis-stable.tar.gz

6. CD redis-stable

8. Make

10. Make install

12. If make has an exception:

14. 1) make[2]: Cc:command not found

16. Exception reason: GCC is not installed

18. Solution: Yum Install gcc-c++

20. 2) zmalloc.h:51:31:error:jemalloc/jemalloc.h:no such file or directory

22. Exception reason: Some compiler dependencies or original compilation legacy problems

24. Solution: Make Distclean. Clean it up and make it again.

26. After make is successful, make test is required to have an exception in make test

28. 1) couldn ' t execute "tclsh8.5": No such file or directory

30. Exception reason: Tcl not installed

32. Solution: Yum install-y tcl.

34. When the make command is completed, 5 executables are generated in the SRC directory, namely Redis-server, REDIS-CLI, Redis-benchmark, redis-check-aof, Redis-check-dump, Their role is as follows:

36. Redis-server:redis Server Daemon Startup program

38. Redis-cli:redis command-line operation tool. Of course, you can also use Telnet to operate on its plain text protocol.

40. Redis-benchmark:redis Performance testing tools to test the read and write performance of Redis in your system and in your configuration

42. Redis-check-aof: Update log check

44. Redis-check-dump: for local database checking

46. Step three, configure

48. CP redis-server/usr/local/bin/

50. CP redis-cli/usr/local/bin/

52. Then create a new directory, store the configuration file

54. Mkdir/etc/redis

56. Mkdir/var/redis

58. Mkdir/var/redis/log

60. Mkdir/var/redis/run

62. mkdir/var/redis/6379

64. Locate the profile template in the Redis solution directory and copy it to the following location.

66. CP redis.conf/etc/redis/6379.conf modified with vim command

68. Daemonize Yes

70. Pidfile/var/redis/run/redis_6379.pid

72. Logfile/var/redis/log/redis_6379.log

74. dir/var/redis/6379

76. Finally, run Redis:

78. $ redis-server/etc/redis/6379.conf

80. Available NETSTAT–ATLN View port is a successful boot installation

84. Step four, Operation Redis database

86. #./redis-cli

90. "http://img.blog.csdn.net/20140617150954812?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvaV9icnVjZQ==/font/ 5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/dissolve/70/gravity/southeast "alt=" "/>

92. Let's take a brief look at the database. In case the instance is turned on:

94. 1. Inserting data

96. Redis 127.0.0.1:6379> Set name WWL

98. Ok

100. Set a Key-value pair.

102. 2. Query data

104. Redis 127.0.0.1:6379> Get Name

106. "WWL"

108. Remove the value corresponding to the key.

110. 3. Delete key values

112. Redis 127.0.0.1:6379> del name

114. Delete this key and the corresponding value.

116. 4. Verify that the key is present

118. Redis 127.0.0.1:6379> exists name

120. (integer) 0

122. 0, which means that the key does not exist; 1 stands for existence.

124. Step five, download the Phpredis extension

126. Download Https://github.com/nicolasff/phpredis/downloads first.

128. #wget https://github.com/nicolasff/phpredis/downloads

130. # TAR-ZXVF Nicolasff-phpredis-2.1.3-124-gd4ad907.tar.gz

132. # MV nicolasff-phpredis-d4ad907 php-5.3.8/ext/phpredis/

134. # CD php-5.3.8/ext/phpredis/

136. #/usr/local/php/bin/phpize

138. #./configure--with-php-config=/usr/local/php/bin/php-config

140. # Make && make install

142. Configure PHP.ini

144. Vi/usr/local/php/lib/php.ini

146. Join

148. Extension=redis.so

150. )

152. First to see if there is extension_dir=/....

154. Restart Apache or nginx (reload PHP--->/etc/init.d/php-fpm restart)

156. To the normal situation, you can see the Redis extension with Phpinfo

158. If Phpinfo does not have Redis extension information, add/etc/php.d/redis.ini (path is my local)

160. Redis.ini content is as follows:

162. ; Enable MySQL Extension module

164. Extension=redis.so

166. Restart Apache or nginx (reload PHP--->/etc/init.d/php-fpm restart)
