MySQL(2)--源码安装
源码方式安装MySQL5.7.11
下载源码：
http://dev.mysql.com/downloads/mysql/
最下面两项
参考安装文档：
http://dev.mysql.com/doc/refman/5.7/en/installing-source-distribution.html
安装问题：
your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found
yum install gcc gcc-c++
---------------
CMake Error at cmake/boost.cmake:81 (MESSAGE):
You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>
cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=boost相对目录
--------------
Curses library not found.
rm CMakeCache.txt
yum install ncurses-devel
---------------
cmake后没有错误，只有警告就可以make && make install继续了
比较完整的cmake脚本
cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/opt/mysql/software/mysql-5.7.11/boost -DCMAKE_INSTALL_PREFIX=/opt/mysql/software -DMYSQL_DATADIR=/opt/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/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 clean
检查/etc/my.cnf是否存在，存在就先去掉
------------------------
/opt/mysql/software/是安装目录进入到bin
./mysqld --initialize-insecure --user=mysql --basedir=/opt/mysql/software --datadir=/opt/mysql/data
如果datadir有内容则会创建失败，需要删除再执行。
[mysq@mysqlserver bin]$ ./mysqld --initialize-insecure --user=mysql --basedir=/opt/mysql/software --datadir=/opt/mysql/data

重启
--------------------
启动出现错误时，查看对应的日志 /opt/mysql/data/mysqlserver.err
Could not create unix socket lock file /my
sql.sock.lock.

修改/etc/my.cnf中, 修改，指定一个有权限的socket
basedir = /opt/mysql/software
datadir = /opt/mysql/data
port = 3306
# server_id = .....
socket = /opt/mysql/data/mysql.sock
-----------------
mysql连接时的错误
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/mysql/data/mysqld.sock' (2)
在最后一行增加
[mysql]
socket = /opt/mysql/data/mysql.sock
两边的socket保持一致
