yum安装mysql
1、下载yum库或者RPM包
2、编写配置文件
vim /etc/yum.repos.d/文件名mysql.repo
[文件名]
(变量)name=(需要变量的字符串)mysql-comm
(解析的地址变量)=(地址)ftp://(ip地址/下载包的目录地址)
3、(查询安装包)yum list |grep mysql-community-server
(安装mysql包)yum intall -y (包名)mysql-community*
4、(启动数据库)systemctl start mysqld
(开机启动) systemctl enable mysqld
5、(验证)ls /var/lib/mysql
(查看相关文件)netstat -anpt |grep mysql
6、(查询登录密码)grep 'password' /var/log/mysqld.log
(使用密码登录)mysql -uroot -p'密码'
(修改密码) ALTER USER 'root'@'localhost' IDENTIFIED BY 'QianFeng@123';
源码安装yum
#1、部署环境
yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make cmake
#2、准备源码包
#创建用户组和用户并给用户权限
groupadd mysql
useradd -r -g mysql -s /bin/false mysql
tar xvf mysql-5.7.19.tar.gz
cd mysql-5.7.19
mv ../boost_1_59_0.tar.gz .
tar xf boost_1_59_0.tar.gz
#3编译前配置
cmake . \
-DWITH_BOOST=boost_1_59_0/ \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DSYSCONFDIR=/etc \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DINSTALL_MANDIR=/usr/share/man \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1
#4、编译
make
#安装
make install
#5、初始化安装位置
cd /usr/local/mysql
#创建一个目录,并设置权限
mkdir mysql-files
chown -R mysql.mysql /usr/local/mysql
#查找mysql临时密码(并保存)
/usr/local/mysql/bin/mysqld --initialize --user=mysql --bsaedir=/usr/local/mysql --datadir=/usr/local/mysql/data
/usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
#创建mysql配置文件mysql.cnf
vim /etc/mysql.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
cp support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
service mysqld start
ps aux |grep mysqld
mysql -u root -p '密码' 登陆有问题吗?
/usr/local/mysql/bin/mysql -u root -p'x/dwiQ2<l:hb'
#重置密码
/usr/local/mysql/bin/mysqladmin -u root -p 'x/dwiQ2<l:hb' password 'QinFeng@123'
#查看库
show databases;
