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
wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
cd /apps/rpm
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
cmake \
-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
- 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
cd /apps/rpm
rm -rf mysql-5.7.31
rm -rf mysql-5.7.31.tar
rm -rf mysql-boost-5.7.31.tar.gz
chown -R apps:apps /apps
chmod -R 755 /apps
- 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
- 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
