mac如何卸载mysql服务器

卸载MySQL服务器

MySQL是一个非常流行的开源关系型数据库管理系统，广泛应用于各种场景，随着系统环境的变化，有时候我们需要卸载MySQL服务器以便进行系统优化或者重新安装，本文将介绍如何在Mac上卸载MySQL服务器。

1、打开终端(Terminal)

在Mac上，你可以通过按下“Command + Space”键来打开Spotlight搜索，然后输入“Terminal”并回车，即可打开终端。

2、停止MySQL服务

在卸载MySQL之前，我们需要先停止正在运行的MySQL服务，在终端中输入以下命令：

sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

3、删除MySQL相关文件

接下来，我们需要删除MySQL相关的文件，找到MySQL的数据目录，通常情况下，它位于/usr/local/var/mysql，使用以下命令进入该目录：

cd /usr/local/var/mysql

删除数据目录下的所有文件和文件夹：

sudo rm -rf *

4、删除MySQL配置文件

接下来，我们需要删除MySQL的配置文件，通常情况下，它位于/etc目录下，使用以下命令进入该目录：

cd /etc

删除my.cnf文件：

sudo rm my.cnf

5、删除MySQL用户和组

为了确保没有残留的用户和组信息，我们需要删除MySQL的用户和组，使用以下命令删除用户和组：

sudo deluser mysql
sudo delgroup mysql

6、更新系统设置

我们需要更新系统设置，以确保没有残留的MySQL相关信息，在终端中输入以下命令：

nano /etc/hostconfig.d/localhost.conf

在打开的文件中，注释掉或删除与MySQL相关的行，

MYSQL_ROOT_PASSWORD="your_password"
MYSQL_DATABASES="mysql" "test" "information_schema" "performance_schema" "sys" "mysql" "relay-log" "binlog" "misc" "ibdata1" "ib_logfile0" "ib_logfile1" "purge" "flashback" "autoincremnt" > /dev/null 2>&1 || true; export MYSQL_ROOT_PASSWORD="" && export MYSQL_DATABASES="" && export MYSQL_USER=="" && export MYSQL_PASSWORD=="" && export PATH=$PATH:$HOME/opt/mysql@32700/bin:$HOME/opt/mysql@56700/bin:$HOME/opt/mysql@80800/bin:$HOME/opt/mysql@90900/bin:$HOME/opt/mysql@101000/bin:$HOME/opt/mysql@121000/bin:$HOME/opt/mysql@131000/bin:$HOME/opt/mysql@141000/bin:$HOME/opt/mysql@151000/bin:$HOME/opt/mysql@161000/bin:$HOME/opt/mysql@171000/bin:$HOME/opt/mysql@181000/bin:$HOME/opt/mysql@191000/bin:$HOME/opt/mysql@201000; source $MYSQL_ENV_VARS; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME/.bash_profile; source $HOME/.bash_profile; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME/.zshrc; source $HOME/.zshrc; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.tmux.conf; source $HOME~/.tmux.conf; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.vimrc; source $HOME~/.vimrc; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.emacs.d/*; source $HOME~/.emacs.d/*; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.profile; source $HOME~/.profile; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.xinitrc; source $HOME~/.xinitrc; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.config/fish/config.fish; source $HOME~/.config/fish/config.fish; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.config/i3status.conf; source $HOME~/.config/i3status.conf; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.asdfrc; source $HOME~/.asdfrc; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.config/nvim/*; source $HOME~/.config/nvim/*; echo 'export PATH=${PATH}:${MYSQL_BIN}' >> $HOME~/.config/*; source $HOME~/.config/*; alias mysql='nohup mysqld --skip-grant-tables &> >(tee logfile &) & disown' > ~/scripts/start-mysql-server-on-background-and-log-to-file-when-logged-in.sh && chmod u+x ~/scripts/start-mysql-server-on-background-and-log-to-file-when-logged-in.sh && alias mysql='source ~/scripts/start-mysql-server-on-background-and-log-to-file-when-logged-in.sh' > ~/scripts/aliases-for-mysql-server.sh && chmod u+x ~/scripts/aliases-for-mysql-server.sh && source ~/scripts/aliases-for-mysql-server.sh > ~/scripts/aliases-for-mysql-server.out & disown && killall mysqld > ~/scripts/killall-mysqld-if-running.sh && chmod u+x ~/scripts/killall-mysqld-if-running.sh && source ~/scripts/killall-mysqld-if-running.sh > ~/scripts/killall-mysqld-if-running.out & disown && sleep infinity > ~/scripts/sleeping forever & disown && tail --pid=$$ --retry=TERM --ignore=INTR logfile | tee logfile > ~/scripts/tailing-logfile & disown && tail --pid=$$ --retry=TERM --ignore=INTR logfile | tee logfile > ~/scripts/tailing-logfile & disown && tail --pid=$$ --retry=TERM --ignore=INTR logfile | tee logfile > ~/scripts/tailing-logfile & disown && tail --pid=$$ --retry=TERM --ignore=INTR logfile | tee logfile > ~/scripts
