1、環(huán)境
| IP | 192.168.109.111 |
| mysql | 5.7 |
2若河、mysql安裝
2.1 查看是否存在mysql組合用戶,若無(wú)則創(chuàng)建
cat /etc/group | grep mysql
cat /etc/passwd | grep mysql
groupadd mysql
useradd -r -g mysql mysql
2.2 準(zhǔn)備工作
(1）傳mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz 到/usr/local
(2）這里mysql數(shù)據(jù)目錄暫定為/data/mysql/ 日志目錄為/data/mysql/log
mkdir -p /data/mysql3306
chown -R mysql:mysql /data/mysql3306
2.3 開始安裝
cd /usr/local/
tar -xf mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.14-linux-glibc2.5-x86_64 mysql3306
chown -R mysql:mysql mysql3306/
cd mysql3306/
bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql3306/ --datadir=/data/mysql3306/
cp -a ./support-files/my-default.cnf /etc/my3306.cnf
cp -a ./support-files/mysql.server /etc/init.d/mysqld3306
2.4 修改/etc/my3306.cnf配置文件笨触，啟動(dòng)mysql
my.cnf配置如下
cat >/etc/my3306.cnf<<EOF

啟動(dòng)mysql
在 /etc/init.d/mysqld3306的46,47行添加
basedir=/usr/local/mysql3306
datadir=/data/mysql3306
重啟mysql
service mysqld3306 start
5 修改mysql密碼
cat /root/.mysql_secret
記錄了mysql的初始密碼
cd /usr/local/mysql/bin
./mysql -uroot -p
輸入密碼 進(jìn)入mysql數(shù)據(jù)庫(kù)
SET PASSWORD = PASSWORD('123456');
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
6添加環(huán)境變量
echo "export PATH=$PATH:/usr/local/mysql3306/bin" >>/etc/profile
source /etc/profile
