mysql 5.5安装

1、安装mysql5.5及5.5以上版本需要安装cmake

1）下载cmake

wget --no-check-certificate http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz

2）解压编译安装

先安装所依赖的包：

yum -y install gcc*

tar zvxf cmake-2.8.7.tar.gz

cd cmake-2.8.7

./configure

make && make install

2、安装mysql

1）下载mysql

wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.47.tar.gz

2）创建mysql用户与用户组

groupadd mysql

useradd -g mysql mysql

3）解压安装

tar zvxf mysql-5.5.47.tar.gz

cd mysql-5.5.47

使用cmake编译：

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/mysql/data \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_EXTRA_CHARSETS:STRING=all \

-DWITH_DEBUG=0 \

-DWITH_SSL=yes \

-DWITH_READLINE=1 \

-DENABLED_LOCAL_INFILE=1

make && make install

4）生成新的mysql权限表

mkdir -p /mysql/data

./scripts/mysql_install_db --user=mysql  -datadir=/mysql/data

#此处如不指定datadir，到启动时会报错

5)权限设置

cd /usr/local/mysql

chown -R mysql:mysql  /usr/local/mysql

chown -R root .

chown -R mysql data

cp support-files/my-medium.cnf /etc/my.cnf

/usr/local/mysql/bin/mysqld_safe --user=mysql &

cp support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

/etc/init.d/mysqld start

6)验证

/usr/local/mysql/bin/mysql
