在Centos 5.4上安装社区版Mysql5.1.41
今天整理电脑的时候发现2年前的安装文档，share下。
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
shell>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=<password> --testhost=localhost--testdb=mysql
shell>make
shell>make test
shell>make install
测试mysqlhotcopy：
shell>mysqlhotcopy -h localhost -u root -p <test> 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
|
+-----------------------------+
1 row in set (0.05 sec)
