编译安装mysql5.5

mysql5.5已经改用cmake编译，编译前请安装cmake;

yum install cmake -y

或者自行下载：

-------------------------------

wget

tar -xvf mysql-5.5.22.tar.gz -C /usr/local/src

groupadd mysql

useradd -r -g mysql mysql

cd /usr/local/src/mysql-5.5.22/

cmake .

make

make install

cd /usr/local/mysql

chown -R mysql .

chgrp -R mysql .

scripts/mysql_install_db --user=mysql

chown -R root .

chown -R mysql data

cp support-files/my-medium.cnf /etc/my.cnf

bin/mysqld_safe --user=mysql &

cp support-files/mysql.server /etc/init.d/mysql.server

==========================

如果要更改mysql编译配置:

make clean

rm -f CMakeCache.txt

重新编译即可

若遇到如下错误提示:

CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

解决:yum install gcc-c++ -y

===========================

mysql的data目录是在/usr/local/mysql/data，你可以移到/data下:

mv /usr/local/mysql/data /

vi /etc/my.cnf的[mysqld]中加入:

datadir = /data
