1、环境介绍

• centos7.9
• mysql5.7.44
• boost1.59.0

注意：这里的编译版本mysql5.7.44和boost1.59.0是有依赖的，建议使用相同版本

2、安装编译要用的依赖软件

yum install -y  gcc gcc-c++ cmake libaio-devel ncurses ncurses-devel bison openssl-devel

3、准备编译的源码包

mysql源码包下载：

• 官网：MySQL :: Download MySQL Community Server
• 

boost源码包下载：

• boost官网：Boost Downloads
• boost官网下载历史版本：Boost Version History
• boost文档：Boost C++ Libraries
• boost-1.59.0：Chapter 43. Boost.Build User Manual - 1.59.0

注意：国内下载这个boost包很慢

#可直接linux上用wget下载



wget https://zenlayer.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz



 



wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.44.tar.gz

4、创建mysql用户

groupadd mysql



useradd -r -g mysql -M -s /sbin/nologin mysql

5、创建数据库目录(此目录可自定义)

mkdir -p /opt/mysql



chown mysql:mysql /opt/mysql



 



#目录自定义后，后面配置文件路径相应要改变

6、编译安装mysql和boost

#将本地下载的2个源码包传至/root



cd /root/



 



tar -xf boost_1_59_0.tar.gz



mv boost_1_59_0 /usr/local/boost



 



tar -xf mysql-5.7.44.tar.gz -C /usr/local/src/



cd /usr/local/src/mysql-5.7.44



cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/opt/mysql  -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/opt/mysql/mysql.sock  -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1    -DDOWNLOAD_BOOST=0 -DWITH_BOOST=../../boost -DWITH_INNODB_MEMCACHED=ON



 



make



make install

7、编辑my.cnf并初始化mysql数据库

#先备份编译安装后自动生成的



mv /etc/my.cnf /etc/my.cnf.bak



 



#自定义my.cnf



cat >/etc/my.cnf<<EOF



[client]



port=3306



socket=/opt/mysql/mysql.sock







[mysqld]



character-set-server=utf8



collation-server=utf8_general_ci







skip-name-resolve



user=mysql



port=3306



basedir=/usr/local/mysql



datadir=/opt/mysql



tmpdir=/tmp



socket=/opt/mysql/mysql.sock







log-error=/opt/mysql/mysqld.log



pid-file=/opt/mysql/mysqld.pid 



EOF



 



 



#根据my.cnf初始化mysql



/usr/local/mysql/bin/mysqld  --defaults-file=/etc/my.cnf   --initialize  --user=mysql



 



 



#开启数据库并查看状态



/usr/local/mysql/support-files/mysql.server start



 



/usr/local/mysql/support-files/mysql.server status



 



 



#查看登录root的初始密码



cat /opt/mysql/mysqld.log | grep root

8、设置mysql环境变量

vi /etc/profile



...



export MYSQL_HOME=/usr/local/mysql



export PATH=$PATH:$MYSQL_HOME/bin



 



 



source /etc/profile

9、修改root的初始密码

#这里用前面查到的初始密码登录



mysql -uroot -p



Enter password:

#关闭数据库服务（为了后面设置的自启正常使用）



/usr/local/mysql/support-files/mysql.server stop

10、设置启动文件以及开机自启

#复制启动文件到常用启动目录



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



 



#编辑启动service



vi /usr/lib/systemd/system/mysql.service
