注意：在虚拟机cmake安装mysql5.5.32时，将虚拟机内存调至2G。（原创，请勿转载！）

一、安装MySQL依赖包

[root@cmake ~]# yum install pcre pcre-devel openssl openssl-devel gcc-c++ ncurses-devel -y

二、安装cmake

官网：https://cmake.org/download/

[root@cmake eleven]# mkdir /home/eleven/tools

[root@cmake eleven]# cd /home/eleven/tools/

[root@cmake tools]# wget https://cmake.org/files/v3.9/cmake-3.9.0.tar.gz

[root@cmake  tools]# tar xf cmake-3.9.0.tar.gz

[root@cmake  tools]# cd cmake-3.9.0

[root@cmake cmake-3.9.0]# ./configure

[root@cmake cmake-3.9.0]# gmake

[root@cmake cmake-3.9.0]# gmake install

[root@cmake cmake-3.9.0]# /usr/local/bin/cmake --version

cmake version 3.9.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

#cmake安装结束，也可以把gmake,gmake install改为make， make install。

#cmake命令默认路径/uer/local/bin/camke，编译mysql用全路径即可。

# /usr/local/bin/cmake --version，查看版本，说明cmake安装正常。

++++++++++++++++++++++++++++++++++

cmake的一些错误做法：

#将cmake命令复制到/usr/bin。

#使用which camke命令查看。

#使用cmake命令编译mysql，都会提示出错。

#必须用全路径 /usr/local/bin/cmake。

错误如下：

[root@cmake cmake-3.9.0]# which cmake

/usr/bin/which: no cmake in (/sbin:/bin:/usr/sbin:/usr/bin)

[root@cmake cmake-3.9.0]# cp /usr/local/bin/cmake /usr/bin/

[root@cmake cmake-3.9.0]# which cmake

/usr/bin/cmake

[root@cmake cmake-3.9.0]# cmake --version

CMake Error: Could not find CMAKE_ROOT !!!

CMake has most likely not been installed correctly.

Modules directory not found in

/usr/share/cmake-3.9

cmake version 3.9.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

三、cmake编译安装MySQL5.5.32

1、上传mysql5.5.32.tar.gz

[root@cmake tools]# rz

[root@cmake tools]# tar xf mysql-5.5.32.tar.gz

[root@cmake tools]# useradd mysql -s /sbin/nologin -M

[root@cmake tools]# cd mysql-5.5.32

[root@cmake mysql-5.5.32]# /usr/local/bin/cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \

-DMYSQL_DATADIR=/application/mysql-5.5.32/data \

-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \

-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \

-DENABLED_LOCAL_INFILE=ON \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \

-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \

-DWITH_FAST_MUTEXES=1 \

-DWITH_ZLIB=bundled \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_READLINE=1 \

-DWITH_EMBEDDED_SERVER=1 \

-DWITH_DEBUG=0 \

-DDEFAULT_CHARSET=utf8 \     #不需要此行

-DDEFAULT_COLLATION=utf8_general_ci \     #不需要此行

为了让默认字符集是什么，就不指定字符集了。

删掉指定字符那两行后，就是默认字符集了，删掉后再编译安装。

[root@cmake mysql-5.5.32]# make

[root@cmake mysql-5.5.32]# make install

[root@cmake mysql-5.5.32]# ln -s /application/mysql-5.5.32/ /application/mysql

[root@cmake mysql-5.5.32]# cp support-files/my-small.cnf /etc/my.cnf

cp: overwrite `/etc/my.cnf'? y

[root@cmake mysql-5.5.32]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql

[root@cmake mysql-5.5.32]# cp /application/mysql/bin/mysql /usr/local/bin/

#如果提示命令不存在，就把mysql命令复制到/usr/bin/目录下。

[root@cmake mysql-5.5.32]# chown -R mysql.mysql /application/mysql/data/

[root@cmake mysql-5.5.32]# chmod -R 1777 /tmp/

[root@cmake mysql-5.5.32]# cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld

[root@cmake mysql-5.5.32]# vim /etc/init.d/mysqld

basedir=/application/mysql

datadir=/application/mysql/data

[root@cmake mysql-5.5.32]# /etc/init.d/mysqld start

Starting MySQL.. SUCCESS!

[root@cmake mysql-5.5.32]# mysql

bash: mysql: command not found

[root@cmake mysql-5.5.32]# cp /application/mysql/bin/mysql /usr/bin

[root@cmake mysql-5.5.32]# mysql
