编译装配 MySQL 5.5.13

编译安装 MySQL 5.5.13

?编译安装 MySQL 5.5.13?

以前没安装过 费了好大力气

		编译安装 MySQL 5.5.13 

建立mysql安装目录及数据存放目录 
# mkdir /usr/local/mysql 
# mkdir /usr/local/mysql/data
# mkdir /usr/local/mysql/etc

创建用户和用户组 
# groupadd mysql 
# useradd -g mysql mysql 

赋予数据存放目录权限 
# chown mysql:mysql –R /usr/local/mysql/data 

通过http://www.mysql.com/downloads/mysql官方网址或国内的sohu镜像下载软件包。 

# wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.13.tar.gz 

# tar zxvf mysql-5.5.13.tar.gz 

# cd mysql-5.5.13 
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ 
-DSYSCONFDIR=/usr/local/mysql/etc \ 
-DMYSQL_DATADIR=/usr/local/mysql/data \ 
-DMYSQL_TCP_PORT=3306 \ 
-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \ 
-DMYSQL_USER=mysql \ 
-DEXTRA_CHARSETS=all \ 
-DWITH_READLINE=1 \ 
-DWITH_SSL=system \ 
-DWITH_EMBEDDED_SERVER=1 \ 
-DENABLED_LOCAL_INFILE=1 \ 
-DWITH_INNOBASE_STORAGE_ENGINE=1 \ 
-DWITHOUT_PARTITION_STORAGE_ENGINE=1 
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql  -DSYSCONFDIR=/usr/local/mysql/etc -DMYSQL_DATADIR=/usr/local/mysql/data -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DMYSQL_USER=mysql  -DEXTRA_CHARSETS=all  -DWITH_READLINE=1  -DWITH_SSL=system -DWITH_EMBEDDED_SERVER=1  -DENABLED_LOCAL_INFILE=1  -DWITH_INNOBASE_STORAGE_ENGINE=1  -DWITHOUT_PARTITION_STORAGE_ENGINE=1 

# make 
# make install 

# make 
# make install 

在make与make install的时候可以看到进度百分比，感觉这一点要比configure方式要好。 

6.配置并初始化数据库 
创建my.cnf配置文件 
# mkdir /usr/local/mysql/log 

# mkdir /usr/local/mysql/etc 
# cp support-files/my-medium.cnf /usr/local/mysql/etc/my.cnf 
修改my.cnf 添加如下内容：
socket          = /tmp/mysqld.sock
datadir = /usr/local/mysql/data


初始化数据库 
执行前需赋给scripts/mysql_install_db文件执行权限 
# chmod 755 scripts/mysql_install_db 
# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 

创建管理MySQL数据库的shell脚本 
# mkdir /usr/local/mysql/init.d 
# cp support-files/mysql.server /usr/local/mysql/init.d/mysql 

赋予shell脚本可执行权限： 
# chmod +x /usr/local/mysql/init.d/mysql 

启动MySQL： 
# /usr/local/mysql/init.d/mysql start 

通过命令行登录管理MySQL服务器（提示输入密码时直接回车）： 
# /usr/local/mysql/bin/mysql -u root -p -S /tmp/mysql.sock 
or
# /usr/local/mysql/bin/mysql -u root -p  

输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）： 
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678'; 
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678'; 

为root帐户设置初始密码 
# /opt/mysql/bin/mysqladmin -u root password 'new-password' 

删除本机匿名连接的空密码帐号 
/usr/local/mysql/bin/mysql -uroot -p'new-password' 
mysql>use mysql; //选择系统数据库mysql 
mysql>select Host,User,Password from user; //查看所有用户 
mysql>delete from user where password=""; 
mysql>flush privileges; 
mysql>select Host,User,Password from user; //确认密码为空的用户是否已全部删除 
mysql>exit;
