##從mysql5.5起，mysql源碼安裝開始使用cmake了，設置源碼編譯配置腳本。 wget --no-check-certificate?https://cmake.org/files/v2.8/cmake-2.8.12.tar.gz tar -zxvf?cmake-2.8.12.tar.gz cd?cmake-2.8.12 ./bootstrap? && make && make install
mkdir -p /usr/local/mysql

mkdir -p /data2/mysqldb chown -R mysql:mysql /usr/local/mysql chown -R mysql:mysql /data2/mysqldb
cp?/usr/local/mysql/support-files/my-default.cnf?/etc/my.cnf chown mysql:mysql /etc/my.cnf ##my.cnf重新配置參數，編譯階段的參數沒寫到這個配置文件去。 #文件配置 vim /etc/my.cnf basedir =/usr/local/mysql datadir =/data2/mysqldb port =3308 # server_id = ..... socket =/usr/local/mysql/data/mysql.sock

#Because the MySQL server,?mysqld, must access the data directory when it runs later, you should either run?mysql_install_db?from the same system account that will be used for running?mysqld /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data2/mysqldb
##指定配置文件 ##/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data2/mysqldb --defaults-file=/usr/local/mysql/my.cnf
mkdir -p /usr/local/mysql/log chown mysql:mysql /usr/local/mysql/log/ mkdir -p /usr/local/mysql/run/mysqld/ chown -R mysql:mysql /usr/local/mysql/run/mysqld/ touch /usr/local/mysql/log/mysqld.log chown mysql:mysql /usr/local/mysql/log/mysqld.log

#To start a second server, provide different?--socket?and?--port?option values, and pass a?--datadir=dir_name?option to?mysqld_safe?so that the server uses a different data directory. mysqld_safe --socket=file_name --port=port_number?--defaults-file=/usr/local/mysql/my.cnf


#安全模式啟動 /usr/local/mysql/bin/mysqld_safe --socket=/usr/local/mysql/data/mysql.sock --port=3308 --defaults-file=/usr/local/mysql/my.cnf
#開啟mysql服務 /usr/local/mysql/support-files/mysql.server start

#密碼為空，如果能登陸上，則安裝成功 /usr/local/mysql/bin/mysql -u root -p
或自定義帶sock文件 /usr/local/mysql/bin/mysql -uroot -p -S /usr/local/mysql/data/mysql.sock
后續步驟： cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld-lastest ?? vim /etc/profile? ? MYSQL_PATH=/usr/local/mysql/bin:/usr/local/mysql/lib ?export MYSQL_PATH?
source /etc/profile ##添加到系統運行級別 chkconfig?--level?35?mysqld?on ##查看端口占用 netstat?-antlp?|?grep?3308
#修改密碼 mysqladmin?-u?root?password?'123456'

/usr/local/mysql/bin/mysqld_safe --skip-grant-tables
問題：? ? ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)? ? 解決：? ? 新建一個鏈接或在mysql中加入-S參數，直接指出mysql.sock位置。? ? ln -s /usr/local/mysql/data/mysql.sock /tmp/mysql.sock? ? /usr/local/mysql/bin/mysql -u root -S /usr/local/mysql/data/mysql.sock
