標籤:密碼 mysql 使用者
根據單一實例進行變更,主要變化檔案為my.cnf檔案和mysql檔案
多執行個體以連接埠區分
需要注意下面檔案內的連接埠的更改,和使用者密碼更改
my.cnf

[[email protected] data]# rm -rf *[[email protected] data]# pwd/application/mysql/data[[email protected] data]#[[email protected] data]# ls
2、建立多執行個體的目錄(連接埠區分)
mkdir /data/{3306,3307}/data -p3、建立my.cnf mysql檔案
[[email protected] 3306]# lsdata my.cnf mysql[[email protected] 3306]#
4、複製相關檔案my.cnf、mysql 到每個目錄下
\cp /data/3306/my.cnf mysql /data/3307/#保證是下面形式[[email protected] data]# tree.├── 3306│ ├── data│ ├── my.cnf│ └── mysql├── 3307 ├── data ├── my.cnf └── mysql
5、修改連接埠號碼與ID
#修改3307sed -i ‘s/3306/3307/g‘ /data/3307/my.cnfsed -i ‘s/server-id = 1/server-id = 7/g‘ /data/3307/my.cnfsed -i ‘s/3306/3307/g‘ /data/3307/mysql
6、初始化
cd /application/mysql/scripts./mysql_install_db --datadir=/data/3306/data--basedir=/application/mysql --user=mysql./mysql_install_db --datadir=/data/3307/data--basedir=/application/mysql --user=mysql
7、授權
chown -R mysql.mysql /data/find /data -type f -name mysql|xargs chmod 700
8、開啟mysql
/data/3306/mysql start/data/3307/mysql start
9、檢查連接埠
[[email protected] scripts]# netstat -lnt|grep 330tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN
10、加入環境變數和開機自啟動
[[email protected] ~]#PATH="$PATH:/application/mysql/bin"[[email protected] ~]# echo‘PATH="$PATH:/application/mysql/bin"‘ >>/etc/profile[[email protected] ~]# . /etc/profile[[email protected] ~]#
11、加入開機自啟動
echo "/data/3306/mysql start" >>/etc/rc.localecho "/data/3307/mysql start" >>/etc/rc.local[[email protected] ~]# tail -2 /etc/rc.local/data/3306/mysql start/data/3307/mysql start[[email protected] ~]#
