今天领导要求使用免编译的方式安装生产环境的mysql,所以才有了下文. 里面涉及的目录已经处理，大家根据需要自己来改吧！ 1 下载
今天领导要求使用免编译的方式安装生产环境的mysql,所以才有了下文. 里面涉及的目录已经处理，大家根据需要自己来改吧！
1 下载mysql免编译包：
1 wget
2 设置mysql目录：
tar -zxvf mysql-5.6.14-免编译方式安装MySQL-5.6.14-glibc2.5-x86_64.tar.gz
mv mysql-5.6.14-免编译方式安装MySQL-5.6.14-glibc2.5-x86_64 /usr/local/mysql
groupadd mysql
useradd -g mysql -M mysql
mkdir -p /work/mysql/data
chown -R mysql.mysql /work/mysql/data
3 初始化MySQL数据库：
#提示:运行下面的命令初始化安装mysql之前确认系统没有/etc/my.cnf
/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/work/mysql/data --user=mysql
4 添加mysqld 成为系统服务并设置自启动：
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
5 启动mysql：
/etc/init.d/mysqld start
6 设置密码：
/usr/local/mysql/bin/mysqladmin -u root password '你的密码'
7 关于my.cnf:
mysqld-5.5以上版本的my.cnf这个文件 在执行初始化的时候，，会自动安装到/usr/local/mysql/my.cnf下。 并且主要修改里面的选项配置
8 故障：
Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
解决办法：
这个问题是需要重新初始化mysql数据库
mysql_install_db --basedir=/usr/local/mysql --datadir=/work/mysql/data --user=mysql
9 关于我的my.cnf：
/usr/local/mysql/my.cnf
# For advice on how to change settings please see
#
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql
datadir = /work/mysql/data
port = 3306
# server_id = .....
socket = /tmp/mysql.sock
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
join_buffer_size = 128M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
ps : 根据上面的内容可以自己做成一键安装脚本。这样就不必像以前那样漫长的等待了.
