--【MySQL源码】源码安装和启动mysql
--------------------------------------2014/08/19
本机环境：ubuntu12.04,fedora-17
MYSQL版本:5.5.28
CMAKE版本:2.8.9
一.下载最新版本的cmake,解压后编译安装.
sudo ./configure --prefix=/usr/local/etc/cmake-2.8.9
sudo make
sudo make install
sudo ln -s /usr/local/etc/cmake-2.8.9/bin/cmake /usr/local/bin/cmake
现在可以使用cmake命令了!
如果出现以下提示，请先安装g++。
---------------------------------------------

C compiler on this system is: cc
---------------------------------------------
Error when bootstrapping CMake:

---------------------------------------------
Log of errors: /usr/local/src/cmake-2.8.9/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------
ubuntu下用
sudo apt-get install g++
redhat系列下用
sudo yum install gcc-c++
下载最新的mysql源码包，解压后，进入其跟目录
sudo cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/etc/mysql-5.5.28 \
-DMYSQL_DATADIR=/usr/local/etc/mysql-5.5.28/data \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \ # 这里附上一行版的，方便粘贴
# 注：此处路径为/opt下，如果要和上面保持一致，请手动修改
# sudo cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql-5.5.28 -DMYSQL_DATADIR=/opt/mysql-5.5.28/data -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DWITH_INNOBASE_STORAGE_ENGINE=1 sudo make
sudo make install --添加debug功能，在cmake后面添加参数-DWITH_DEBUG=ON
更多参数选项，参考官方文档：http://dev.mysql.com/doc/refman/5.7/en/source-configuration-options.html
如果编译过程出现如下错误 需安装libncurses5-dev
-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:83 (MESSAGE):
Curses library not found. Please install appropriate package, remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:127 (FIND_CURSES)
cmake/readline.cmake:217 (MYSQL_USE_BUNDLED_LIBEDIT)
CMakeLists.txt:268 (MYSQL_CHECK_READLINE) -- Configuring incomplete, errors occurred!
sudo apt-get install libncurses5-dev
#删除编译缓存信息
sudo rm -rf CMakeCache.txt
编译完成后创建数据库
./scripts/mysql_install_db --user=root --basedir=/opt/mysql-5.5./ --datadir=/opt/mysql-5.5./data/
创建完成后就可以启动数据库了
./bin/mysqld_safe --defaults-file=/etc/my.cnf --datadir=/opt/mysql-5.5./data/ --basedir=/opt/mysql-5.5./ --port= --user=root&
不知道是否是因为最新版本mysql 5.7的限制，我使用忽略权限表的方式登录数据库后，将密码修改为空，然后重启mysqld，再已空密码登录成功。
而后进行查询和创建数据库操作，报以下错误：
ERROR 1820 (HY000): You must SET PASSWORD before executing this statement
通过：set password=password("");即可解决问题。
