1. 下載MySQL5.6.38安裝包mysql
下載地址:https://www.mysql.com/downloads/ 打開網站以後選擇Archiveslinux
而後再選擇開源版本c++
選擇咱們要下載的版本sql
2. 編譯安裝MySQL5.6.38數據庫
# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) # 建立系統賬號 # groupadd -r mysql # useradd -r -g mysql -s /sbin/nologin mysql # 關閉SELinux # setenforce 0 # sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config # 安裝依賴包 # yum install ncurses-devel libaio-devel -y # yum install cmake gcc gcc-c++ make autoconf -y # 上面若是沒有下載安裝包,可直接wget下載 # wget https://cdn.mysql.com/archives/mysql-5.6/mysql-5.6.38.tar.gz # tar xf mysql-5.6.38.tar.gz # cd mysql-5.6.38/ # 進行編譯安裝 [ ~/mysql-5.6.38]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.6.38 \ # 指定安裝目錄 -DMYSQL_DATADIR=/usr/local/mysql-5.6.38/data \ # 指定數據目錄 -DMYSQL_UNIX_ADDR=/usr/local/mysql-5.6.38/mysql.sock \ # 指定sock文件位置 -DDEFAULT_CHARSET=utf8 \ # 默認字符集 -DDEFAULT_COLLATION=utf8_general_ci \ # 默認編碼 -DWITH_EXTRA_CHARSETS=all \ # 其它額外字符集 -DWITH_INNOBASE_STORAGE_ENGINE=1 \ # 支持的存儲引擎 -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \ -DWITH_SSL=bundled \ # 編譯其它功能SSL、ZLIB等 -DWITH_ZLIB=bundled \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_EMBEDDED_SERVER=1 \ -DENABLE_DOWNLOADS=1 \ -DWITH_DEBUG=0 -DSYSCONFDIR=/etc [ ~/mysql-5.6.38]# make && make install # 編譯並安裝數據庫 # 作軟連接並給MySQL目錄受權 # ln -s /usr/local/mysql-5.6.38/ /usr/local/mysql # chown -R mysql.mysql /usr/local/mysql
3. 初始化數據目錄vim
# MySQL 5.6初始化數據庫的命令: # /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data -user=mysql # MySQL 5.7初始化數據庫的命令: # /usr/local/mysql/bin/mysqld --initialize-insecure --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data -user=mysql
4. 拷貝啓動服務的腳本安全
# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld # chmod 700 /etc/init.d/mysqld
5. 修改環境變量socket
# echo 'PATH=/usr/local/mysql/bin:$PATH' >>/etc/profile # source /etc/profile
6. 修改配置文件,並啓動數據庫網站
# vim /etc/my.cnf [mysqld] server_id=1 port=3306 basedir=/usr/local/mysql datadir=/usr/local/mysql/data socket=/usr/local/mysql/mysql.sock log_bin=/usr/local/mysql/mysql-bin log_error=/var/log/mysql.log character-set-server=utf8 [client] socket=/tmp/mysql.sock # /etc/init.d/mysqld start
7. 設置數據庫密碼並清空MySQL不安全賬號編碼
# mysqladmin -u root password 123456 # mysql -uroot -p123456 # 清除不安全的用戶,先查詢用戶名爲空和沒有密碼的 > select user,password,host from mysql.user; > drop user root@'127.0.0.1'; > drop user ''@'localhost';
