mysql5.5以上编译方法

Yum install cmake –y
编译的方法：
cmake .-DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql-DCOMMUNITY_BUILD:BOOL=ON -DENABLED_PROFILING:BOOL=ON -DENABLE_DEBUG_SYNC:BOOL=OFF-DINSTALL_LAYOUT:STRING=STANDALONE -DMYSQL_DATADIR:PATH=/var/run/mysql-DMYSQL_MAINTAINER_MODE:BOOL=OFF -DWITH_EMBEDDED_SERVER:BOOL=ON-DWITH_EXTRA_CHARSETS:STRING=all -DWITH_SSL:STRING=bundled-DWITH_UNIT_TESTS:BOOL=OFF -DWITH_ZLIB:STRING=bundled -DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_USER=mysql-DMYSQL_TCP_PORT=3306 -LH make make install
报错误-- Configuringincomplete, errors occurred!没有安装 ncurses-devel 或者yum install gcc gcc-c++ -y 并且删除CMakeCache.txt 这个文件可以find 查找一个这个目录在哪里 groupadd mysql
useradd -g mysql mysql
cp/usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
vim /etc/my.cnf #需要加入basedir,和datadir否则会出问题
[mysqld]
basedir =/usr/local/mysql
datadir =/usr/local/mysql/data

chown -R mysql /usr/local/mysql/data
chgrp -R mysql /usr/local/mysql/. cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
/usr/local/mysql/scripts/mysql_install_db--user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &
chmod 755 /etc/init.d/mysql
chkconfig --level 345 mysql on
/etc/init.d/mysql start
/usr/local/mysql/bin/mysqladmin -u rootpassword 你的MYSQL密码
OK终于完成~my.cnf优化
[client]
#password = your_password
port = 3306
socket = /data/mysql/data/mysqld.sock
default-character-set = utf8
# The MySQL server
[mysqld]
port = 3306
socket = /data/mysql/data/mysqld.sock
log-error = /data/mysql/data
pid-file = /data/mysql/data/hrd.pid

net_buffer_length = 8K
read_buffer_size = 1M
tmp_table_size = 16M

slow-query_log
slow-query_log_file = /data/mysql/data/slow.log
lower_case_table_names = 1
15、mysql字符集优化
SHOW VARIABLES LIKE 'CHARACTER%'; 查看字符环境
1、在[client]字段里加入default-character-set=utf8，如下：
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8
2、在[mysqld]字段里加入character-set-server=utf8，如下：
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
character-set-server=utf8
遇到的问题：MySQL: Starting MySQL…..ERROR! The server quit without updating PID file

解决过程：

[root@localhost ~]# cd /usr/local/mysql[root@localhostmysql]# chown -R mysql.mysql .
[root@localhost mysql]# su- mysql
[mysql@localhost ~]$ cd/usr/local/mysql
[mysql@localhost mysql]$ scripts/mysql_install_db

Filling help tables...
OKTo start mysqld at boottime you have to copy
support-files/mysql.server to the right place for your systemPLEASE REMEMBER TOSET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:./bin/mysqladmin -uroot password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'Alternatively youcan run:
./bin/mysql_secure_installationwhich will also giveyou the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.See the manual formore instructions.You can start theMySQL daemon with:
cd . ; ./bin/mysqld_safe &You can test theMySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.plPlease report any problemswith the ./bin/mysqlbug script![mysql@localhostmysql]$ /usr/local/mysql/bin/mysqld_safe--user=mysql &
