mysql-MHA预发布环境架构分享(二)之mysql源码安装

安装mysql源码包：

(1).安装cmake

（mysql5.5以后是通过cmake来编译的）

下载解压cmake-2.8.5.tar.gz

tar zxf cmake-2.8.12.2.tar.gz -C /usr/local/src

cd /usr/local/src/cmake-2.8.12.2

./configure --prefix=/usr/local/cmake

make && make install

export PATH=/usr/local/cmake/bin:$PATH

【必须依赖包】

cmake make gcc ncurses-devel gcc-c++

(2).安装mysql

 groupadd mysql

 useradd -s /sbin/nologin -g mysql mysql

cd /app/mysql_soft

 tar xf mysql-5.6.17.tar.gz

cd mysql-5.6.17

cmake \

-DCMAKE_INSTALL_PREFIX=/app/mysql \

-DMYSQL_DATADIR=/app/mysql/data \

-DMYSQL_UNIX_ADDR=/app/mysql/data/mysql.sock \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_EXAMPLE_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \

-DMYSQL_TCP_PORT=3306 \

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DMYSQL_USER=mysql \

-DWITH_DEBUG=0

 make && make install

 chown -R mysql.mysql /app/mysql

 cd /app/mysql/scripts/

 ./mysql_install_db --user=mysql --basedir=/app/mysql --datadir=/app/mysql/data

cd ..

 cd support-files/

 cp mysql.server /etc/rc.d/init.d/mysql

 cp my-default.cnf /etc/my.cnf

 chkconfig --add mysql

 chkconfig mysql on

 service mysql start

 ln -s /app/mysql/bin/* /usr/bin/

mysqladmin -u root password ‘mysql‘     #设置数据库root密码为mysql#

##############修改配置文件##############

vi /etc/my.cnf

[mysqld]

datadir=/app/mysql/data

socket =/app/mysql/data/mysql.sock

lower_case_table_names=1

character-set-server=utf8

collation-server=utf8_general_ci

[client]

default-character-set=utf8

[mysql.server]

user=mysql

basedir=/app/mysql

default-character-set=utf8

[mysqld_safe]

err-log=/app/mysql/errlog/mysqld.log

注意：

如果报：

 mysqladmin: connect to server at ‘localhost‘ failed

error: ‘Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)‘

Check that mysqld is running and that the socket: ‘/var/lib/mysql/mysql.sock‘ exists!

[client]   增加

socket =/app/mysql/data/mysql.sock
