Linux 源码安装MySQL5.7

1.下载源码包

在mysql官网选择合适的版本，得到下载的url

https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22.tar.gz 或者直接修改url

使用wget命令下载

cd /usr/local/src

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22.tar.gz

下载完成之后解压安装包

tar -zxvf mysql-5.7.22.tar.gz

下载boost

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

tar -zxvf boost_1_59_0.tar.gz 

mv boost_1_59_0 /usr/local/boost

进入mysql安装包

cd /usr/local/src/mysql-5.7.22

2.安装

卸载CentOS7默认携带的mariadb包

rpm -qa | grep -i mysql 
rpm -qa | grep -i mariadb

卸载时，发现有依赖一起卸载掉

rpm -e mariadb-libs-5.5.56-2.el7.x86_64

rpm -e mariadb-libs-5.5.56-2.el7.x86_64 postfix-2:2.10.1-6.el7.x86_64

 

先安装一些依赖库

 

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

创建用户组和用户

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

源码编码编译：

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=/usr/local/boost \
-DSYSCONFDIR=/etc \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DENABLE_DTRACE=0 \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EMBEDDED_SERVER=1

编译

make && make install

cd /usr/local/mysql/

3.配置

设置权限

chown -R mysql:mysql /usr/local/mysql 

添加配置文件

vi /etc/my.cnf

写入

初始化mysql

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

添加MySQL环境变量

vi /etc/profile

增加

/usr/local/mysql/bin:

刷新环境变量

source /etc/profile

设置开机自启动

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld

启动mysql

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

查看mysql进程

ps -ef | grep mysql

登陆MySQL

mysql -uroot

 

修改密码

 

SET PASSWORD = PASSWORD('123456');

退出mysql

quit;

重新登录mysql

mysql -uroot -p

输入上面设置的密码：123456

成功登录

配置远程访问

use mysql;

UPDATE user SET host = '%' WHERE user = 'root';

重启mysql

quit;
/etc/init.d/mysqld restart

 

 

 

使用 Navicat连接

使用 cmd 连接mysql（需安装Windows的mysql）

安装完成
