mysql基础-新版5.7.10源码安装-记录(一)

0x01

　　MySQL 从 5.5 版本开始，通过 ./configure 进行编译配置方式已经被取消，取而代之的是 cmake 工具

　　引用一句话

　　cmake的重要特性之一是其独立于源码(out-of-source)的编译功能，即编译工作可以在另一个指定的目录中而非源码目录中进行，这可以保证源码目录不受任何一次编译的影响，因此在同一个源码树上可以进行多次不同的编译，如针对于不同平台编译。

　　所以首先要安装cmake 可以源码安装也可以 使用已经编译好的rpm包进行安装

　　yum安装  yum install cmake -y

　　源码安装  下载源码 wget --no-check-certificate https://www.cmake.org/files/v3.4/cmake-3.4.1.tar.gz

　　解压 cmake     tar -zxvf cmake-3.4.1.tar.gz

　　编译安装 ./configure --prefix=/usr/local/cmake  make && make install

　　做个软链接 ln -s /usr/local/cmake/bin/cmake /usr/bin/cmake

　　执行 cmake --help  成功！

　　开始安装源码mysql

　　在搜狐的镜像下载源码

　　wget -c http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.10.tar.gz

　　解压源码包

　　tar -zxvf mysql-5.7.10.tar.gz

　　根据自己的要求选择需要编译的模块

　　建立mysql安装目录及数据存放的目录

　　mkdir /usr/local/mysql   ----安装文件的目录

　　mkdir /mydata/mysql/log   ----二进制日志目录，做主从同步使用

　　mkdir /mydata/mysql/data  ----数据库数据目录  PS：数据目录一定不要和mysql程序安装目录放在一起

　　创建mysql 用户和组

　　groupadd -r -g 306 mysql    ---创建一个mysql组指定gid 为306 -r是创建为一个系统用户

　　useradd -g mysql -u 306 -r -s /sbin/nologin mysql    ---创建用户mysql 指定uid 为306 shell为非登录shell的系统用户 归属mysql组

　　开始编译安装 ，但是报错 如下

进行下载对应包即可

wget -c http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz

解压到指定文件并改名

tar -zxvf boost_1_59_0.tar.gz -C /tmp

mv /tmp/boost_1_59 /usr/local/boost

再编译安装

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/mydata/mysql/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 -DWITH_BOOST=/usr/local/boost

上面编译完成 make 过程曲折，一直过不去，后来根据大神经验

发现非常好用内存，故 更改测试环境虚拟机内存至 4 G 才解决

后面make install 很顺利，完成mysql源码安装

下面开始初始化准备工作：如下

　　更改安装好的mysql路径下的文件拥有组

　　chown -R :mysql /usr/local/mysql/

　　更改mysql的数据目录和日志目录拥有人和拥有组

　　创建目录 mkdir /var/run/mysql

　　复制默认配置文件到对应目录  

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

 

my.cnf 配置文件内容

　　开始初始化

 bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/mydata/mysql/data/

初始化密码是 g2gd_/0y0,+I

　　复制mysql的自动启停脚本

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

将mysql服务添加到管理服务中，让其开机启动

　　chkconfig --add mysqld

　　chkconfig --list | grep mysqld

启动mysql

使用刚才上面生成密码 进入mysql

登录成功，迅速修改root密码

alter user 'root'@'localhost' identified by 'your password';

flush privileges;

 

将mysql客户端设置环境变量，让其正常使用

通过 如下添加mysql.sh

vim /etc/profile.d/mysql.sh   ---- 添加 ----> export PATH=/usr/local/mysql/bin:$PATH

让其生效

source /etc/profile.d/mysql.sh
