MySQL编译安装

Posted 2021-02-14 dulingyulove

一、mysql安装

yum安装：

vim /etc/yum.repos.d/mysql.repo

[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

yum -y install mysql
yum  -y  install  mysql-community-server.x86_64

初始化数据库

mysqld --initialize --user=mysql

或编译安装的

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

启动、关闭、重启、开机自启动数据库

systenctl start mysqld
systemctl stop mysqld
systemctl restart mysqld
systemctl enable mysqld

查找初始密码

grep  ‘password‘  /var/log/mysqld.log

登录数据库

mysql -u root -p‘8N4:=!QJee?.‘

修改密码

ALTER USER‘root‘@‘localhost‘ IDENTIFIED BY ‘[email protected]‘;

编译安装

 #从MySQL 5.7.5开始Boost库是必需的

wget https://sourceforge.net/projects/boost/files/boost/1.68.0/boost_1_68_0.tar.gz

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.25-el7-x86_64.tar.gz

安装依赖包

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

cd /root/oneinstack/src

useradd -M -s /sbin/nologin mysql

预编译

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../boost_1_59_0 -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=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EMBEDDED_SERVER=1

编译安装

#编译很消耗系统资源，小内存可能编译通不过

make -j `grep processor /proc/cpuinfo | wc -l` 
make install

启动脚本，设置开机自启动

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

启动数据库

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

设置数据库密码

dbrootpwd=oneinstack #数据库root密码
/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to [email protected]‘127.0.0.1‘ identified by "$dbrootpwd" with grant option;"
/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to [email protected]‘localhost‘ identified by "$dbrootpwd" with grant option;"
