mysql服务未启动：地址已在使用中

我正在尝试在ubuntu上安装mysql-5.5.29源代码。 每次我重新启动或启动服务时，它都会告诉我MySQL守护进程无法启动

shell>>service mysql.server start

昨天安装mysql时，我使用了：

cmake . -DCMAKE_INSTALL_PREFIX="/usr/local/mysql" \
-DMYSQL_UNIX_ADDR=/var/lib/mysql

但是当我使用时，我发现/var/lib/mysql是空的：

shell>> ll /var/lib/mysql
drwxr-xr-x  2 root root 4096  1月  2 23:38 ./
drwxr-xr-x 65 root root 4096  1月  2 23:38 ../

3306插座似乎没有使用

端口3306中还有另一个软件正在侦听。试着做

netstat -na | grep LISTEN netstat-na| grep LISTEN

---

然后看看这是不是真的。3306不应该在那里。如果您看到某个端口正在侦听，那么在尝试启动MySQL之前必须先关闭该端口

130106 12:20:28 [ERROR] Can't start server : Bind on unix socket: Address already in use
130106 12:20:28 [ERROR] Do you already have another mysqld server running on socket: /var/lib/mysql ?

查找正在使用的程序

/var/lib/mysql

lsof /var/lib/mysql

杀了它

kill -HUP `lsof -t /var/lib/mysql`

也尝试卸载它

---

现在重新安装您新安装的服务器

您是否尝试过使用超级用户权限执行此操作？是的，我使用超级用户执行此操作可能重复感谢，3306端口未在netstat中列出-na | grep LISTEN“无法启动服务器：在unix套接字上绑定：地址已在使用”表示另一个软件正在侦听该端口。你必须检查两次或三次。我又检查了一遍，没有找到3306插座。我已经公布了结果{你能把MySQL端口从3306改成其他的吗，它在/etc的my.cnf文件中，或者如果你是从代码编译的话，它在同一个文件夹中。把3306端口改成类似1036的东西，检查它是否启动。哈，我解决了。-DMYSQL_UNIX_ADDR=/var/lib/MySQL是错误的。我把它改成了DMYSQL_UNIX_ADDR=/var/lib/MySQL/MySQL.sock
