shell_一键部署Mysql脚本

一.一键部署Mysql

1.将安装Mysql所需软件包传到/opt目录下

#!/bin/bash

systemctl stop firewalld
setenforce 0

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

useradd -M -s /sbin/nologin  mysql

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz

cd /opt/mysql-5.7.20/
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8  \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1

make && make install

chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile	
source /etc/profile



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

cd /usr/local/mysql/bin/
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/

systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld
netstat -anpt | grep 3306


if [ $? -eq 0 ];then
        echo "Mysql安装成功！"
else
        echo 启动失败
        exit 1
fi

read -p "输入登录Mysql密码" c
mysqladmin -u root -p password "$c"

注意：启动脚本一定要source启动脚本

• sh 启动脚本，source /etc/profile 重载刷新配置文件命令会不生效。需要装完，
• 再启动执行source /etc/profile 才生效。

解释为啥source/ect/profile不生效原因

可授权远程登录

mysql -u root -p123456
grant all privileges on *.* to 'root'@'%' identified by '123456';
#授予root用户可以在所有终端远程登录，使用的密码是123456，并对所有数据库和所有表有操作权限

show databases;			#查看当前已有的数据库
