mysql5.7 for centos7.6源码安装

1.安装前的准备

1) 关闭防火墙修改SELinux

vim /etc/selinux/config

SELINUX=disabled

2)关闭防火墙

systemctl status firewalld.service

systemctl stop firewalld.service

systemctl disable firewalld.service

3）检查操作系统上是否安装了MySQL

rpm -qa |grep mariadb

yum remove mysql-libs

rpm -qpi xxxx.rpm

4）安装MySQL所需要的工具

yum install \

vim \

git \

gcc \

gcc-c++ \

wget \

make \

cmake \

automake \

autoconf \

libaio \

libtool \

net-tools \

bison \

bison-devel \

libaio-devel \

ncurses-devel \

perl-Data-Dumper \

-y

yum -y install openssl openssl-devel

2.添加用户和组:

groupadd apps

useradd -d /home/apps -g apps -m apps

passwd apps

3.创建目录及授权

mkdir -p /apps/dbdat/mysql57_3306

mkdir -p /apps/binlog/mysql57_3306

mkdir -p /apps/conf/mysql

mkdir -p /apps/logs/mysql

mkdir -p /apps/svr/mysql57

mkdir -p /apps/tmp

mkdir -p /apps/run

mkdir -p /apps/sh/tool

mkdir -p /apps/rpm

chown -R apps:apps /apps

chmod -R 755 /apps

4.配MySQL环境变量

vi /etc/profile

export LANG=en_US.UTF-8

export PATH=$PATH:/usr/sbin

export PATH=$PATH:/apps/svr/mysql57/bin

export PATH=$PATH:/apps/sh/tool/

export MYSQL_HISTFILE=/dev/null

~/.mysql_history

source /etc/profile

5.下载/解压

cd /apps/rpm

wget

http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.28.tar.gz http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz

tar -xzvf boost_1_59_0.tar.gz

tar -xzvf mysql-5.7.28.tar.gz

6.进入解压完的mysql-5.7.27目录，编译源码并生成makefile。

cd mysql-5.7.31

编译并安装

-DCMAKE_INSTALL_PREFIX=/apps/svr/mysql57 \

-DMYSQL_DATADIR=/apps/dbdat/mysql57_3306 \

-DSYSCONFDIR=/apps/conf/mysql \

-DWITH_BOOST=/apps/rpm/mysql-5.7.31/boost \

-DDEFAULT_CHARSET=utf8mb4 \

-DDEFAULT_COLLATION=utf8mb4_unicode_ci \

-DEXTRA_CHARSETS=all \

-DENABLED_LOCAL_INFILE=1 \

-DMYSQL_UNIX_ADDR=/tmp/mysql3306.sock \

-DMYSQL_TCP_PORT=3306

-DWITH_SYSTEMD=1 \ 去掉这个，加上不会安装mysqld_safe

1. 编译

make -j 4

make -j

grep processor /proc/cpuinfo | wc -l && make install

8.安装

make install

9.配置mysql参数

vim /apps/conf/mysql/mysql57_3306.cnf

rm -rf mysql-5.7.31

rm -rf mysql-5.7.31.tar

rm -rf mysql-boost-5.7.31.tar.gz

1. 初始化数据库：(-–datadir目标目录下不能有数据文件)

su - apps

/apps/svr/mysql57/bin/mysqld --defaults-file=/apps/conf/mysql/mysql57_3306.cnf --initialize-insecure --user=apps #root 密码为空

1. 启动MySQL：

nohup /apps/svr/mysql57/bin/mysqld_safe --defaults-file=/apps/conf/mysql/mysql57_3306.cnf --user=apps &

12.登录mysql

mysql

13.修改密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root123';

14.重新登录

mysql -uroot -p
