Install redis and phpRedis extension in linux-php Tutorial

Install redis and phpRedis extensions in linux

1. Install redis and php Redis extension in linux

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

3. Step 1. download redis

4. You can download the latest version at http://redis.io/

5. I use 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

1. Step 2. compile the source program

2. Tar xvzf redis-stable.tar.gz

3. Cd redis-stable

4. Make

5. Make install

6. If an exception occurs in make:

7. 1) make [2]: cc: Command not found

8. Cause of exception: gcc is not installed

9. Solution: yum install gcc-c ++

10. 2) zmalloc. h: 51: 31: error: jemalloc/jemalloc. h: No such file or directory

11. Cause of exception: Some compilation dependencies or issues left behind by the original compilation

12. Solution: make distclean. Clean up and then make.

13. After make is successful, make test has an exception in make test.

14. 1) couldn't execute "tclsh8.5": no such file or directory

15. Cause of exception: tcl is not installed

16. Solution: yum install-y tcl.

17. After the make command is executed, five executable files are generated in the src directory, they are redis-server, redis-cli, redis-benchmark, redis-check-aof, and redis-check-dump. Their functions are as follows:

18. Redis-server: daemon startup program of the Redis server

19. Redis-cli: Redis command line operation tool. Of course, you can also use telnet to operate based on its plain text protocol.

20. Redis-benchmark: Redis performance testing tool to test the read/write performance of Redis in your system and your configuration

21. Redis-check-aof: update log check

22. Redis-check-dump: used for local database check

23. Step 3. configure

24. Cp redis-server/usr/local/bin/

25. Cp redis-cli/usr/local/bin/

26. Create a directory to store the configuration file.

27. Mkdir/etc/redis

28. Mkdir/var/redis

29. Mkdir/var/redis/log

30. Mkdir/var/redis/run

31. Mkdir/var/apsaradb for redis/6379

32. Find the configuration file template in the redis root directory and copy it to the following location.

33. Cp redis. conf/etc/redis/6379. conf is modified using the vim command

34. Daemonize yes

35. Pidfile/var/redis/run/redis_62.16.pid

36. Logfile/var/redis/log/redis_62.16.log

37. Dir/var/redis/6379

38. Finally run redis:

39. $ Redis-server/etc/redis/6379. conf

40. Use netstat-atln to check whether the port is successfully installed.

42. Step 4: operate the Redis database

43. #./Redis-cli

45. "Http://img.blog.csdn.net/20140617150954812? Watermark/2/text/plain =/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA =/dissolve/70/gravity/SouthEast "alt ="/>

46. Next we will perform a simple operation on the database. When the instance is enabled:

47. 1. Insert data

48. Redis 127.0.0.1: 6379> set name wwl

49. OK

50. Set a key-value pair.

51. 2. query data

52. Redis 127.0.0.1: 6379> get name

53. "Wwl"

54. Obtain the value corresponding to the key.

55. 3. delete a key value

56. Redis 127.0.0.1: 6379> del name

57. Delete the key and the corresponding value.

58. 4. check whether the verification key exists

59. Redis 127.0.0.1: 6379> exists name

60. (Integer) 0

61. 0 indicates that the key does not exist; 1 indicates that the key exists.

62. Step 5. download phpredis extension

63. Download the https://github.com/nicolasff/phpredis/downloads first

64. # Wget https://github.com/nicolasff/phpredis/downloads

65. # Tar-zxvf nicolasff-phpredis-2.1.3-124-gd4ad907.tar.gz

66. # Mv nicolasff-phpredis-d4ad907 php-5.3.8/ext/phpredis/

67. # Cd php-5.3.8/ext/phpredis/

68. #/Usr/local/php/bin/phpize

69. #./Configure -- with-php-config =/usr/local/php/bin/php-config

70. # Make & make install

71. Configure php. ini

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

73. (Add:

74. Extension = redis. so

75. )

76. First, check whether there is extension_dir = /.......

77. Restart apache or nginx (reload php --->/etc/init. d/php-fpm restart)

78. By now, you can use phpinfo to view the redis extension.

79. If phpinfo does not have redis extension information, add/etc/php. d/redis. ini (the path is my local)

80. The content of redis. ini is as follows:

81. ; Enable mysql extension module

82. Extension = redis. so

83. Restart apache or nginx (reload php --->/etc/init. d/php-fpm restart)
