mysql 的安装

安装MYSQL

 1. 卸载已有mysql

  查看是否已安装mysql:

  rpm -qa mysql

  有则卸载:

  rpm -e --nodeps 文件名称

  是否存在与mysql相关的文件或目录:

  whereis mysql

  是则删除。

  查看是否存在mariadb:

  rpm -qa | grep mariadb

  存在则卸载:

  rpm -e --nodeps 文件名 //文件名是上一个命令查询结果

  存在/etc/my.cnf,则需要先删除:

  rm /etc/my.cnf

  2. 安装编译mysql需要的依赖包

  yum install libevent* libtool* autoconf* libstd* ncurse* bison* openssl*

  3. 安装cmake(mysql5.5之后需要用cmake支持编译安装)

  查看是否已安装cmake:

  rpm -qa cmake

  没有则下载编译安装:

  cd /usr/local/src

  wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz

  tar -xf cmake-2.8.12.1.tar.gz

  cd cmake-2.8.12.1

  ./configure

  make

  make install

  检查cmake是否安装成功:

  cmake --version

  4. 下载mysql包并解压(到/usr/local/src目录)

  cd /usr/local/src

  wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.38.tar.gz

  tar -zxvf mysql-5.6.38.tar.gz

  5. 编译安装(到/usr/local/mysql目录)

  cd mysql-5.6.38

  cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -  DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

  make(此过程需花费大概20-30分钟)

  make install

  6. 配置mysql

  groupadd mysql

  useradd -M -g mysql -s /sbin/nologin mysql

  chown -R mysql:mysql /usr/local/mysql

  7. 初始化配置

  cd /usr/local/mysql/scripts

  ./mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

  8. 设置mysql为系统服务

  vim /lib/systemd/system/mysql.service

文件内容:

  [Unit]

  Description=mysql

  After=network.target

  [Service]

  Type=forking

  ExecStart=/usr/local/mysql/support-files/mysql.server start

  ExecStop=/usr/local/mysql/support-files/mysql.server stop

  ExecRestart=/usr/local/mysql/support-files/mysql.server restart

  ExecReload=/usr/local/mysql/support-files/mysql.server reload

  PrivateTmp=true

  [Install]

  WantedBy=multi-user.target

  9. 设置mysql服务开机自启动

  systemctl enable mysql.service

  10. 启动mysql

  systemctl start mysql.service

  查看是否启动成功:

  ps -A| grep mysql

  11. 登录mysql并设置root密码:

  /usr/local/mysql/bin/mysql -u root

  set password=password('root');
