Centos7.3中安装MySQL5.7

首先安装相关环境包

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

添加MySQL程序用户

useradd -s /sbin/nologin mysql

解压软件包

tar zxvf mysql-5.7.17.tar.gz -C /opt/
tar zxvf boost_1_59_0.tar.gz -C /usr/local/ 解压c++运行库
cd /usr/local/
mv boost_1_59_0 boost 重命名，方便管理

cd mysql-5.7.17/

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_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=/usr/local/boost \
-DWITH_SYSTEMD=1

• 注意：如果在CMAKE的过程中有报错，当报错解决后，需要把源码目录中的CMakeCache.txt文件删除，然后再重新CMAKE，否则错误依旧。

make && make install

chown -R mysql.mysql /usr/local/mysql/

vi /etc/my.cnf

[client]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
character_set_server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket = /usr/local/mysql/mysql.sock
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

更改MySQL用户属主属组

chown mysql:mysql /etc/my.cnf

添加环境变量

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

复制服务启动脚本

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld
netstat -anpt | grep 3306

systemctl enable mysqld 设置开机自启动

设置mysql登录用户账户

mysqladmin -u root -p password "abc123" //给root账号设置密码为abc123提示输入的是原始密码。

mysql -u root -p

授权远程登录

grant all privileges on . to 'root'@'%' identified by 'abc123' with grant option;
