源码编译mysql5.5过程记录

官网安装教程：

http://dev.mysql.com/doc/refman/5.5/en/installing-source-distribution.html

CentOS6.3源码安装mysql-5.5.27

#mysql5.5以上使用cmake代替configure编译，首先须要安装cmake

yum install cmake

# 建mysql用户和组

shell> groupadd mysql

shell> useradd -r -g mysql mysql

# 解压tgz包，编译mysql

shell> tar zxvf mysql-5.5.27.src.tar.gz

shell> cd mysql-5.5.27

shell> cmake .

shell> make && make install

# 编译结束

# 更改用户和组属性，执行mysql_install_db初始化数据库

shell> cd /usr/local/mysql

shell> chown -R mysql:mysql .

shell> scripts/mysql_install_db --user=mysql

shell> chown -R root .

shell> chown -R mysql data

# （如下命令可选）拷贝配置文件到/etc目录下，启动mysql

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

shell> bin/mysqld_safe --user=mysql &

# （如下命令可选）设置mysql开机自启动

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

安装过程并不顺利，遇到好几回错误

1.没有安装 gcc 和 gcc-c++，执行cmake报以下错误：

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

[root@ice  mysql-5.5.27]# cmake .

-- The C compiler identification is unknown

-- The CXX compiler identification is unknown

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

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

.

.

.

-- Configuring incomplete, errors occurred!

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

解决方法：安装gcc和gcc-c++

yum install gcc

yum install gcc-c++

#删除cache文件，不删除还会报错

rm CMakeCache.txt 

cmake .

2.编译快结束时，又报以下错误：

Warning: Bison executable not found in PATH

解决方法：安装bison

yum install bison

rm CMakeCache.txt 

cmake .

#编译经过

make && make install

#执行时间比较长

3.没法启动mysql

bin/mysqld_safe --user=mysql & 没法启动

解决方法：

再执行一次scripts/mysql_install_db --user=mysql

为何会这样，缘由不明
