因root账号启动mysql数据库存在严重安全隐患,请在启动时使用mysql账号!
创建组和用户:
[root@mysqldb2 ~]# groupadd mysql [root@mysqldb2 ~]# useradd -g mysql mysql
解压缩安装包:
[root@mysqldb2 ~]# cd /home/mysql/Desktop [root@mysqldb2 Desktop]# tar xvfz mysql-5.5.24.tar.gz [root@mysqldb2 Desktop]# cd mysql-5.5.24
检查依赖的软件包,如果缺少相关的软件包,可通过yum install或rpm安装:
cmake gcc* gcc-c++* autoconf* automake* zlib* libxml* ncurses-devel* libmcrypt* libtool* bison rpm -qa |grep 需要root权限执行
进入mysql安装包目录,执行cmake并加载适当参数:
root>#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ -DWITH_SERVER_SUFFIX=lihui_edition -DENABLED_LOCAL_INFILE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_READLINE=1 -DWITH_SSL=yes -DWITH_EMBEDDED_SERVER=1 -DWITH_PTHREAD=1 -DMYSQL_USER=mysql -DWITH_MYSQLD_LDFLAGS=-all-static -DWITH_INNOBASE_STORAGE_ENGINE=1 > /home/mysql/mysql_setuplogs_cmake.log 2>&1
MySQL 从5.5版本开始,通过./configure进行编译配置方式已经被取消,取而代之的是cmake 工具。
我相信大多数人都已经习惯了之前的configure方式,并且所使用的参数也是比较个性化的,换成cmake之后,这一方面会带来不少的麻烦。
还好,MySQL的官方网站提供了二者的参数对照表,我们可以尽可能的保留之前的参数,来编译配置新的MySQL 版本。
configure 与cmake 参数对照指南:

提示:如果编译不成功,重新编译需要删除mysql安装包目录下的CMakeCache.txt文件
root>#rm CMakeCache.txt
继续执行编译:
root>#make > /home/mysql/mysql_setuplogs_make.log 2>&1 root>#$make install > /home/mysql/mysql_setuplogs_makeinstall.log 2>&1
PS:make时注意新开一个会话,用tail -200f /home/mysql/mysql_setuplogs_make.log查看编译日志,审查有无报错。但下述警告可忽略:
警告:提领类型双关的指针将破坏强重叠规则
修改相关路径权限:
root># cd /usr/local/ root># chown -R mysql:mysql mysql
复制程序文件到/usr/bin目录下,方便调用:
[root@mysqldb2 local]# cp /usr/local/mysql/bin/mysql* /usr/bin/
至此,MySQL数据库软件安装完全,此时已可使用mysql命令行工具连接其它MySQL数据库服务器了。
创建目录并修改权限:
[root@mysqldb2 local]# cd /data0 [root@mysqldb2 data]# mkdir mysqldata [root@mysqldb2 data]# cd mysqldata [root@mysqldb2 mysqldata]# mkdir 3306 [root@mysqldb2 mysqldata]# cd 3306 [root@mysqldb2 3306]# mkdir data binlog tmp innodb_ts innodb_log [root@mysqldb2 3306]# cd /data0 [root@mysqldb2 data]# chown -R mysql:mysql mysqldata
创建数据库:
[root@mysqldb2 local]# cd /usr/local/mysql/ [root@mysqldb2 mysql]# scripts/mysql_install_db --user=mysql --datadir=/data0/mysqldata/3306/data
Installing MySQL system tables... OK Filling help tables... OK
To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands:
/usr/local/mysql/bin/mysqladmin -u root password 'new-password' /usr/local/mysql/bin/mysqladmin -u root -h 192.168.66.32 password 'new-password'
Alternatively you can run: /usr/local/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with: cd /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &
You can test the MySQL daemon with cd /usr/local/mysql/mysql-test ; perl
Please report any problems with the /usr/local/mysql/scripts/mysqlbug script!

启动数据库:
mysql>$ mysqld_safe --defaults-file=/etc/my.cnf &
设置超级用户密码:
mysql>$mysqladmin -uroot password 'xxx' -S /data0/mysqldata/3306/mysql.sock
可以通过netstat或ps等命令查看mysqld是否正常加载,由于默认指定mysqld端口号为3306,因此通过netstat查看是否存在3306端口即可,例如:
mysql>$netstat -lnt

进入mysql安装目录下的支持文件目录
[root@mysqldb2 mysql]# cd /usr/local/mysql/support-files/
复制服务文件以使MYSQL能用service直接启动
[root@mysqldb2 mysql]# cp ./mysql.server /etc/init.d/mysqld
再拷贝已配置好的cnf参数文件到/etc/my.cnf,方便service启动时的读取
[root@mysqldb2 mysql]# cp /data/mysqldata/3306/my.cnf /etc/my.cnf
现在就可以很方便的用service命令来启动、关闭MYSQL服务器了
[mysql@mysqldb2 mysql]$ service mysqld restart
