MySQL5.7.20编译安装

1：官网下载source code源码安装文件

https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.20.tar.gz

2：安装准备

先看一下文件和路径：

[root@16-31 mysql]# pwd

/home/mysql

[root@16-31 mysql]# ls

mysql-boost-5.7.20.tar.gz

我们看一下官网给出的源码安装需要的条件：

CMake, which is used as the build framework on all platforms. CMake can be downloaded from http://www.cmake.org.

A good make program. Although some platforms come with their own make implementations, it is highly recommended that you use GNU make 3.75 or higher. It may already be available on your system as gmake. GNU make is available from http://www.gnu.org/software/make/.

A working ANSI C++ compiler. See the description of the FORCE_UNSUPPORTED_COMPILER. option for some guidelines.

The Boost C++ libraries are required to build MySQL (but not to use it). Boost 1.59.0 must be installed. To obtain Boost and its installation instructions, visit the official site. After Boost is installed, tell the build system where the Boost files are located by defining the WITH_BOOST option when you invoke CMake. For example:

shell> cmake . -DWITH_BOOST=/usr/local/boost_1_59_0

Adjust the path as necessary to match your installation.

The ncurses library.

Sufficient free memory. If you encounter problems such as “internal compiler error” when compiling large source files, it may be that you have too little memory. If compiling on a virtual machine, try increasing the memory allocation.

Perl is needed if you intend to run test scripts. Most Unix-like systems include Perl. On Windows, you can use a version such as ActiveState Perl.

上面是官网给的例子，我们先需要下载一个Boost C++ 1.59.0（这是一组扩充C++功能的经过同行评审（Peer-reviewed）且开放源代码程序库。大多数的函数为了能够以开放源代码、封闭项目的方式运作，而授权于Boost软件许可协议（Boost Software License）之下。），下载地址：

https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz/download

接下来我们开始进行一些准备工作（安装依赖包，用户以及目录）：

yum -y install gcc gcc-c++ ncurses ncurses-devel bison libgcrypt perl make cmake

groupadd mysql

useradd -r -g mysql -s /bin/false -M mysql

mkdir -p /home/mysql/{data,log,tmp}

ls /home/mysql/

chown -R mysql:mysql /home/mysql/

3：安装

解压两个压缩文件，MySQL和Boost，然后开始进行编译安装：

[root@16-31 mysql-5.7.20]# cmake . -DCMAKE_INSTALL_PREFIX=/home/mysql -DMYSQL_DATADIR=/home/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DENABLE_DOWNLOADS=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost

然后进行make

make

这个过程时间会比较久，我这边大概两个小时的样子，然后安装：

make install

然后我们先把安装目录添加到环境变量中：

[root@mdw mysql]# echo "export PATH=$PATH:/home/mysql/bin">>/etc/profile

[root@mdw mysql]# source /etc/profile

以上步骤完成以后就是初始化数据库了：

[root@mdw datafile]# mysqld --defaults-file=/etc/my.cnf  --initialize --user='mysql' --log_error_verbosity --explicit_defaults_for_timestamp

OK，现在我们初始化也完成了，接下来我们配置一下我们的my.cnf文件

这里要说明下，就是参数要根据自己的机器配置，不能直接照抄使用，然后直接启动mysql:

mysqld_safe --defaults-file=/etc/my.cnf &

我们从日志中找到初始密码：

--11T06::.094646Z  [Note] A temporary password is generated for root@localhost: ,fsQ:tkik6un

登录修改密码就好了。最后，我们将我们的编译包打包，以后可以直接拷贝使用。

4：解压使用编译压缩包

先拷贝：

scp   /home/mysql.tar  sa@172.16.16.34:/home/sa/

解压：

[root@sdw1 home]# mv mysql.tar /home/

[root@sdw1 home]# tar zxvf mysql.tar

然后我们创建MySQL相关的用户和目录以及授权等：

groupadd mysql

useradd -r -g mysql -s /bin/false -M mysql

mkdir -p /home/datafile/mysql3306/{data,log,temp}

ls /home/datafile/mysql3306

chown -R mysql:mysql /home/datafile/mysql3306

echo "export PATH=$PATH:/home/mysql/bin">>/etc/profile

source /etc/profile

然后使用刚才配置文件再初始化一下（要修改个别参数）：

[root@sdw1 mysql3306]# mysqld --defaults-file=/etc/my.cnf  --initialize --user='mysql' --log_error_verbosity --explicit_defaults_for_timestamp

[root@sdw1 mysql3306]# mysqld_safe --defaults-file=/etc/my.cnf &

然后找到密码初始化搞定。
