mysql-5.1.70linux安装

安装前准备

如果MySQL用户不存在，那么添加mysql用户

 
 groupadd mysql 

 
 useradd  
 -g mysql mysql 

 
 mysql编译安装 

 
 wget http: 
 //downloads 
 .mysql.com 
 /archives/mysql-5 
 .1 
 /mysql-5 
 .1.70. 
 tar 
 .gz 

 
 tar  
 -zxvf mysql-5.1.70. 
 tar 
 .gz 

 
 cd  
 mysql-5.1.70 

 
 yum  
 install  
 ncurses ncurses-devel 

./configure '--prefix=/usr/local/mysql' '--without-debug' '--with-charset=utf8' '--with-extra-charsets=all' '--enable-assembler' '--with-pthread' '--enable-thread-safe-client' '--with-mysqld-ldflags=-all-static' '--with-client-ldflags=-all-static' '--with-big-tables' '--with-readline' '--with-ssl' '--with-embedded-server' '--enable-local-infile' '--with-plugins=innobase'

make

make install

到此mysql就安装到了/usr/local/mysql路径下，下面开始mysql的配置工作

安装mysql选项文件

cp support-files /my-medium .cnf /etc/my .cnf

mysql设置开机自启动

cp -r support-files/mysql.server /etc/init.d/mysqld

/sbin/chkconfig --del mysqld

/sbin/chkconfig --add mysqld

配置权限表

chown -R mysql:mysql /usr/local/mysql

/usr/local/mysql/bin/mysql_install_db --user=mysql

启动mysql

/etc/init .d /mysqld start

登陆mysql

mysql -u root -p

密码默认不输入

这一步可能会报错
/etc/init.d/mysqld: line 260: my_print_defaults: command not found
/etc/init.d/mysqld: line 263: my_print_defaults: command not found
/etc/init.d/mysqld: line 270: @HOSTNAME@: command not found
/etc/init.d/mysqld: line 279: @HOSTNAME@: command not found
/etc/init.d/mysqld: line 292: cd: @prefix@: No such file or directory
Starting MySQLCouldn't find MySQL manager (@bindir@/mysqlmanager) or server (@bindir@/mysqld_safe) [FAILED]

因为路径没有设置，请重启确认上面配置工作是否都完成，一般是configure后没有make和make install。

mysql初始化配置：

 
  export 
   PATH= 
  /usr/local/mysql/bin 
  :$PATH 
 

 
  /usr/local/mysql/bin/mysql_secure_installation 
 

   mysql如何导入旧的数据： 
  
直接拷贝数据库文件夹到数据目录下然后执行

 
  /usr/local/mysql/bin/mysqladmin 
   -u root -p flush-tables

mysql安装过程中问题
1.
make[2]: Entering directory `/down/webinstall/mysql-5.1.57/mysql-test
make[3]: Entering directory `/down/webinstall/mysql-5.1.57/mysql-test
make[3]: Nothing to be done for `install-exec-am.
make INSTALL_TO_DIR="/usr/local/mysql/mysql-test" install_test_files
make[4]: Entering directory `/down/webinstall/mysql-5.1.57/mysql-test
时间较长
MYSQL安装到这里卡了很久，可能以为出错了，实际上MYSQL已经安装成功了，它这步过段时间就会好了，是mysql在自我编译测试造成的。
2.checking for termcap functions library... configure: error: No curses/termcap library found
yum install ncurses ncurses-devel
3.Starting MySQL.Manager of pid-file quit without updating fi[FAILED]
启动数据库之前，需要先配置权限表，其中/usr/local/mysql为mysql的安装目录
chown -R mysql:mysql /usr/local/mysql
/usr/local/mysql/bin/mysql_install_db --user=mysql
 
修改mysql 默认密码：

mysql-5.1.70linux安装
