支持事务处理的mysql的安装，测试入门

robinhunan

1. 
   
2. 让mysql支持事务
   
3. 
   
4. 1.下载二进制版本没，而不需要编译
   
5. 下载地址 http://dev.mysql.com/get/Downloads/MySQL-4.0/mysql-standard-4.0.24-pc-linux-gnu-i686.tar.gz/from/http://mysql.ihostunit.com/
   
6. 
   
7. 2. 安装mysql
   
8.      shell>; groupadd mysql
   
9.      shell>; useradd -g mysql mysql
   
10.      shell>; cd /usr/local
    
11.      shell>; gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf -
    
12.      shell>; ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql
    
13.      shell>; cd mysql
    
14.      shell>; scripts/mysql_install_db --user=mysql
    
15.      shell>; chown -R root  .
    
16.      shell>; chown -R mysql data
    
17.      shell>; chgrp -R mysql .
    
18.      shell>; bin/mysqld_safe --user=mysql &
    
19. 
    
20. 3.使用mysql随系统自动启动
    
21. shell>; echo "/usr/local/mysql/bin/mysqld_safe --user=mysql &" >;>; /etc/rc.local
    
22. 
    
23. 4.查看inodb信息
    
24.      shell>; /usr/local/mysql -u root -p
    
25.      mysql>; show variables like "have_%"
    
26. 系统会提示：
    
27. +------------------+-------+
    
28. | Variable_name    | Value |
    
29. +------------------+-------+
    
30. | have_bdb         | YES   |
    
31. | have_crypt       | YES   |
    
32. | have_innodb      | YES   |
    
33. | have_isam        | YES   |
    
34. | have_raid        | YES   |
    
35. | have_symlink     | YES   |
    
36. | have_openssl     | NO    |
    
37. | have_query_cache | YES   |
    
38. +------------------+-------+
    
39. 8 rows in set (0.05 sec)
    
40. 如果是这样的，那么我们就可以创建一张支持事务处理的表来试试了。
    
41. 
    
42. 5.测试mysql的事务处理
    
43.   mysql>; use test;
    
44.   #创建一个支持事务处理的数据表
    
45.   mysql>; CREATE TABLE student (id INT, name CHAR (20), index (id)) TYPE = InnoDB;
    
46.   #正常插入
    
47.   mysql>; INSERT INTO student VALUES(1,"Jack");
    
48.   mysql>; select * from student;
    
49. +------+------+
    
50. | id   | name |
    
51. +------+------+
    
52. |    1 | Jack |
    
53. +------+------+
    
54. 1 row in set (0.01 sec)
    
55. #开始事务处理
    
56. mysql>; set autocommit=0;
    
57. mysql>; INSERT INTO student VALUES(2,"wind");
    
58. mysql>; insert into student values(3,"liu");
    
59. #提交一个事务
    
60. mysql>; COMMIT;
    
61. 
    
62. 
    
63. mysql>; select * from student;
    
64. +------+------+
    
65. | id   | name |
    
66. +------+------+
    
67. |    1 | Jack |
    
68. |    2 | wind |
    
69. |    3 | liu  |
    
70. +------+------+
    
71. 3 rows in set (0.00 sec)
    
72. 
    
73. 
    
74. #测试事务回滚操作
    
75. msyql>;insert into student values(4,"liu");
    
76. 
    
77. mysql>; select * from student;
    
78. +------+------+
    
79. | id   | name |
    
80. +------+------+
    
81. |    1 | Jack |
    
82. |    2 | wind |
    
83. |    3 | liu  |
    
84. |    4 | liu  |
    
85. +------+------+
    
86. 4 rows in set (0.00 sec)
    
87. # 事务回滚
    
88. mysql>; RollBack;
    
89. 
    
90. mysql>; select * from student;
    
91. +------+------+
    
92. | id   | name |
    
93. +------+------+
    
94. |    1 | Jack |
    
95. |    2 | wind |
    
96. |    3 | liu  |
    
97. +------+------+
    
98. 3 rows in set (0.01 sec)
