inf -- bug kcon config 卸載centos 連接 collation root 1.安裝之前的準備
-
卸載centos7自帶的mariadb
rpm -qa|grep mariadb #查看一下是否有mariadb相關的包 rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64 #把查詢到的包卸載
- 下載mysql安裝包
wget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.60.tar.gz
- 下載cmake安裝包
wget https://cmake.org/files/v3.10/cmake-3.10.2.tar.gz
- 添加mysql用戶和組
groupadd mysql useradd mysql -s /sbin/nologin -M -g mysql # -s /sbin/nologin 表示禁止該用戶登錄,加強安全; -g mysql 指定屬於mysql組; -M 表示不創建用戶家目錄
- 安裝ncurses-devel
yum install ncurses-devel -y
- 安裝cmake
tar zxvf cmake-3.10.2.tar.gz -C /usr/local cd /usr/local/cmake-3.10.2 ./configure gmake && gmake install
2.安裝myqsl
tar zxvf mysql-5.5.60.tar.gz cd mysql-5.5.60 cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.60 -DMYSQL_DATADIR=/application/mysql-5.5.60/data -DMYSQL_UNIX_ADDR=/application/mysql-5.5.60/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=ON -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITH_FAST_MUTEXES=1 -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DWITH_READLINE=1 -DWITH_EMBEDDED_SERVER=1 -DWITH_DEBUG=0 make && make install
-
做軟連接
ln -s /application/mysql-5.5.60/ /application/mysql
-
mysql目錄授權
chown -R mysql:mysql /application/mysql-5.5.60/
-
復制相關文件
cd /application/mysql/support-files cp my-small.cnf /etc/my.cnf cp mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld
- mysql初始化
cd /application/mysql/scripts/ ./mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql
- 啟動mysql
/etc/init.d/mysqld start
- 配置環境變量
echo ‘export PATH=/application/mysql/bin:$PATH‘>>/etc/profile source /etc/profile
- 配置登陸密碼
/application/mysql//bin/mysqladmin -u root password ‘zacs164.com‘
-
設置mysql開機啟動
chkconfig mysqld on chkconfig --list mysqld #查看一下
- 登錄mysql
正常的情況是可以正常登陸進去的,但是我在登錄的時候報了以下錯誤信息:
ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)
解決方法:
- 1.停止mysql數據庫
/etc/init.d/mysqld stop
- 2.執行如下命令
mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
- 3.使用root登錄mysql數據庫
mysql -u root mysql
- 4.更新root密碼
UPDATE user SET Password=PASSWORD(‘ZACS164.COM‘) where USER=‘root‘;
- 5.刷新權限
FLUSH PRIVILEGES;
- 6.退出mysql
-
7.重啟mysql
/etc/init.d/mysqld restart
- 8.使用root用戶重新登錄mysql
