mysql error

ERROR 1290 (HY000): The MySQL server is running with the --read-only option so it cannot execute this statement 
mysql> set global read_only=off

===================================================================================
启动mysqld时报错： ERROR! The server quit without updating PID file (/usr/local/mysql/data/Master.pid).
解决方案：没有在/etc/my.cnf里指定datadir 
cmake -DCMAKE_INSTALL_PREFIX=/home/mysql -DMYSQL_DATADIR=/home/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost


===================================================================================
libmysqlclient_r.so.16
libmysqlclient.so.20
当程序报找不到这库时，请重新安装mysql-libs,
把mysql安装目录下lib/libmysqlclient.so.20 复制到/usr/lib64/libmysqlclient.so.20 ，这系统是64位的。

安装mysql时没有显示临时密码
执行mysqld --initialize --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
后没有显示临时密码
解决方案：可以在/data/mysql/data/error.log里找到临时密码
