在Centos 5.4上安装社区版Mysql5.1.41

安装Mysql服务，提供公司内部应用系统数据库服务。

PC机环境：IntelE5300 内存4G 硬盘500G

操作系统：Linux Centos 5.4

IP：192.168.0.23

2. 安装准备

shell>yum update –y

shell>yum –y install gcc gcc-c++ perl libtool ncurses-devel

shell>groupadd mysql

shell>useradd -g mysql mysql

3. 安装

shell>cd /tmp

shell>wgethttp://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.41.tar.gz/from/http://mirror.trouble-free.net/mysql_mirror/

shell>tar zxvf mysql-5.1.41.tar.gz

shell>cd mysql-5.1.41

shell>./configure –prefix=/usr/local/mysql –without-debug–with-extra-charsets=all –with-charset=utf8 –exec-prefix=/usr/local/mysql–with-pthread –enable-assembler –enable-thread-safe-client–with-mysqld-user=mysql –with-plugins=all –with-client-ldflags=-all-static–with-mysqld-ldflags=-all-static –with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock

shell>make

shell>make install

注：

ec2 安装mysql参考：错误：/usr/bin/ld: cannot find –lncursesw

解决：yum install ncurses-static –with-client-ldflags=”-all-static-ltinfo”（configure参数）

注 :make报错

ERROR 1 : checking for termcap functions library…configure: error: No curses/termcap library found

解决办法:

Shell>yum list|grep ncurses

Shell>yum -y install ncurses-devel

Shell>yum install ncurses-devel

ERROR 2: checking for termcap functions library… configure: error: No curses/termcaplibrary found

解决办法:

Shell>yum list|grep ncurses

Shell>yum -y install ncurses-devel

Shell>yum install ncurses-devel

在/tmp/mysql-5.1.53/目录下

Shell>yum install automake autoconf libtool

Shell>autoreconf –force –install

Shell>libtoolize –automake –force

Shell>automake –force –add-missing

shell>cd /usr/local/mysql

shell>bin/mysql_install_db –user=mysql

shell>chown -R root:mysql .

shell>chown -R mysql /usr/local/mysql

shell>chgrp -R mysql .

shell>cp share/mysql/my-huge.cnf /etc/my.cnf

s本文来源gaodai#ma#com搞*!代#%^码网5hell>ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

shell>ln -s /usr/local/mysql/bin/mysqladmin /usr/bin/

shell>ln -s /usr/local/mysql/bin/mysqld_safe /usr/bin/

shell>ln -s /usr/local/mysql/share/mysql/mysql.server/usr/bin/

shell>ln -s /usr/local/mysql/bin/mysqldump /usr/bin/

4. 安装后配置

4.1. 设置mysql自动启动脚本

shell>cd /usr/local/mysql

shell>cp ./share/mysql/mysql.server /etc/rc.d/init.d/mysqld

shell>chmod 755 /etc/rc.d/init.d/mysqld

shell>chkconfig –-add mysqld

shell>chkconfig –-level 345 mysqld on

可以使用以下命令启停mysql服务或查看当前mysql服务状态

shell>/etc/init.d/mysqld start

shell>/etc/init.d/mysqld stop

shell>/etc/init.d/mysqld status

4.2. 设置root密码

shell>/usr/local/mysql/bin/mysqladmin –u root password‘password’

4.3. 安装DBI和DBD

由于需要使用mysqlhotcopy，需要安装以下部分：

n DBI

shell>cd /tmp

shell>wget http://search.cpan.org/CPAN/authors/id/T/TI/TIMB/DBI-1.609.tar.gz

shell>tar xzvf DBI-1.609.tar.gz

shell>cd DBI-1.609

shell>perl Makefile.PL

shell>make

shell>make install

n DBD::mysql

shell>cd /tmp

shell>wget http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.013.tar.gz

shell>PATH=$PATH:/usr/local/mysql/bin;export PATH

shell>LD_LIBRARY_PATH=/usr/local/mysql/lib/mysql;exportLD_LIBRARY_PATH

shell>unset LANG

shell>tar xzvf DBD-mysql-4.013.tar.gz

shell>cd DBD-mysql-4.013

shell>perl Makefile.PL –mysql_config=/usr/local/mysql/bin/mysql_config–testuser=root –testpassword= –testhost=localhost–testdb=mysql

shell>make

shell>make test

shell>make install

测试mysqlhotcopy：

shell>mysqlhotcopy -h localhost -u root -p test/tmp

当出现以下类似结果时，表示mysqlhotcopy可以正常使用：

'test' is an empty database

No tables to hot-copy at /usr/local/mysql/bin/mysqlhotcopy line380.

或者：

Locked 1 tables in 0 seconds.

Flushed tables (`test`.`test`) in 0 seconds.

Copying 3 files…

Copying indices for 0 files…

Unlocked tables.

mysqlhotcopy copied 1 tables (3 files) in 0 seconds (0 secondsoverall).

4.4. 安装mysql UDF（可选）

由于系统需要，需要能在mysql中调用外部命令，通过安装以下mysql模块就可以实现。

下载源代码：

http://www.mysqludf.org/lib_mysqludf_sys/lib_mysqludf_sys_0.0.3.tar.gz

shell>tar -zxvflib_mysqludf_sys_0.0.3.tar.gz

shell>vim Makefile

注：修改Makefile中gcc参数

原参数为：gcc -Wall -I/usr/include/mysql-I. -shared lib_mysqludf_sys.c -o $(LIBDIR)/lib_mysqludf_sys.so

修改为：gcc -Wall -I/usr/local/mysql/include/mysql-I. -shared lib_mysqludf_sys.c -o /usr/local/mysql/lib/mysql/plugin/lib_mysqludf_sys.so-fPIC

shell>./install.sh

注：编译完成后会连接mysql数据库，建立mysql函数。脚本会提示输入mysql的root用户密码。

测试mysqlUDF

登录mysql数据库，运行一下SQL语句

mysql> select sys_eval(“echohelloworld”);

返回以下结果表示UDF建立成功。

+—————————–+

| sys_eval(“echohelloworld”) |

+—————————–+

| helloworld

|

+—————————–+
