1、测试环境

主机名	IP	系统	mysql版本
MySQL-00	192.168.10.23	CentOS release 6.9 (Final)	5.5.56

2、部署

2.1 卸载之前版本

rpm -qa|grep mysql
rpm -e --nodeps mysql-libs-5.1.73-8.el6_8.x86_64

2.2 安装依赖包和cmake

yum -y install ncurses-devel libaio-devel cmake

2.3 创建用户和目录

useradd mysql -s /sbin/nologin -M
mkdir /app

2.4 编译安装

2.4.1 解压

cd /opt
tar zxf mysql-5.5.56.tar.gz
cd mysql-5.5.56

2.4.2  编译安装

cmake . -DCMAKE_INSTALL_PREFIX=/app/mysql-5.5.56 -DMYSQL_DATADIR=/app/mysql-5.5.56/data -DMYSQL_UNIX_ADDR=/app/mysql-5.5.56/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii -DENABLED_LOCAL_INFILE=ON -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 -DWITHOUT_PARTITION_STORAGE_ENGINE=1 -DWITH_FAST_MUTEXES=1 -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DWITH_READLINE=1 -DWITH_EMBEDDED_SERVER=1 -DWITH_DEBUG=0
make && make install

2.4.3 创建tmp目录及配置文件

mkdir /app/mysql-5.5.56/tmp
cd /app/mysql-5.5.56
cp support-files/my-small.cnf /etc/my.cnf
chown -R mysql.mysql /app/mysql-5.5.56
chmod -R 1777 /app/mysql-5.5.56/tmp

2.4.4 初始化

cd /app/mysql/scripts/
./mysql_install_db --basedir=/app/mysql-5.5.56/ --datadir=/app/mysql-5.5.56/data/ --user=mysql

cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
ln -s /app/mysql-5.5.56 /app/mysql
cp /app/mysql-5.5.56/bin/* /usr/local/sbin/
chkconfig --add mysqld
chkconfig mysqld on
