一. 前言
由于mysql 5.5.7之后使用cmake编译。本篇简单介绍mysql的安装和配置。
二. 环境准备
1.操作系统
CentOS 6.4 x86_64
2.软件版本
mysql-5.5.37 #下载地址：http://dev.mysql.com/downloads/file.php?id=451429 ，需要申请oracle账号才能下载。
3.需要安装的依赖包
cmake
gccgcc-c++ncurses-develbisonopenssl-devel
4. 安装过程：
创建mysql用户，以及数据目录（家目录）
#mkdir -p /mydata/data
#groupadd -r mysql
#useradd -g mysql -r -d /mydata/data mysql
解压mysql5.5.37的源码包到指定目录
#tar -zvxf mysql-5.5.37.tar.gz -C /tmp
使用cmake 编译安装mysql5.5.37
#cd /tmp/mysql-5.5.37
#cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DMYSQL_DATADIR=/mydata/data \-DSYSCONFDIR=/etc \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_ARCHIVE_STORAGE_ENGINE=1 \-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \-DWITH_READLINE=1 \-DWITH_SSL=system \-DWITH_ZLIB=system \-DWITH_LIBWRAP=0 \-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci#make&&make install
##如果编译出错，解决问题后重新编译需要删除当前目录下（/tmp/mysql-5.5.37）的CMakeCache.txt。然后重新编译。
复制配置文件
#cp /usr/local/mysql/support-files/my-large.cnf /etc/my.cnf
复制启动脚本和配置开机自动启动
#cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
#chmod +x /etc/init.d/mysqld
#chkconfig –add mysqld
#chkconfig mysqld on
修改my.cnf配置
#vim /etc/my.cnf##在[mysqld]下添加：datadir=/usr/local/mysql/data
初始化数据库
#/usr/local/mysql/scripts/mysql_install_db --user=mysql--basedir=/usr/local/mysql --datadir=/mydata/data
启动mysqld
#service mysqld start
由于mysql客户端所在目录不在PATH（环境变量），所以需要添加到PATH中
#vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
执行mysql客户端连接。
[root@test01 support-files]# mysql

删除匿名用户
mysql>DROP USER ‘‘@localhost;
mysql>DROP USER ‘‘@test01;
为root账户添加密码
mysql>UPDATE user SET password=PASSWORD(‘password‘) WHERE user=‘root‘;或者[root@test01 support-files]# mysqladmin -u root password ‘password‘
如果root密码忘记了，修改/etc/init.d/mysqld,修改前别忘记备份。修改完成后重新启动mysqld
原文件：case "$mode" in
‘start‘)
cd $basedir
echo $echo_n "Starting MySQL"
iftest -x $bindir/mysqld_safe
then
$bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &
wait_for_pid created "$!" "$mysqld_pid_file_path"; return_value=$?
iftest -w "$lockdir"
then
touch "$lock_file_path"
fi
exit $return_value
else
log_failure_msg "Couldn‘t find MySQL server ($bindir/mysqld_safe)"
fi
;;
修改后：case "$mode" in
‘start‘)
cd $basedir
echo $echo_n "Starting MySQL"
iftest -x $bindir/mysqld_safe
then
$bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" --skip-grant --skip-networking $other_args >/dev/null 2>&1 &
wait_for_pid created "$!" "$mysqld_pid_file_path"; return_value=$?
iftest -w "$lockdir"
then
touch "$lock_file_path"
fi
exit $return_value
else
log_failure_msg "Couldn‘t find MySQL server ($bindir/mysqld_safe)"
fi
