Ubuntu 10.04 下源码编译mysql5.5.x

1. 安装cmake
$ sudo apt-get install cmake

2. 安装libncurses5-dev
$ sudo apt-get install libncurses5-dev

$ rm CMakeCache.txt

$ cmake . -LH # 查看支持的参数

$ sudo apt-get install bison

$ rm CMakeCache.txt

$ cmake . -LH

$ rm CMakeCache.txt

$ cmake . \

# 执行后的提示
# To start mysqld at boot time you have to copy
# support-files/mysql.server to the right place for your system
#
# PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
# To do so, start the server, then issue the following commands:
#
# /opt/apps/mysql-5.5.21/bin/mysqladmin -u root password 'new-password'
# /opt/apps/mysql-5.5.21/bin/mysqladmin -u root -h tony-laptop password 'new-password'
#
# Alternatively you can run:
# /opt/apps/mysql-5.5.21/bin/mysql_secure_installation
#
# which will also give you the option of removing the test
# databases and anonymous user created by default. This is
# strongly recommended for production servers.
#
# See the manual for more instructions.
#
# You can start the MySQL daemon with:
# cd /opt/apps/mysql-5.5.21 ; /opt/apps/mysql-5.5.21/bin/mysqld_safe &
#
# You can test the MySQL daemon with mysql-test-run.pl
# cd /opt/apps/mysql-5.5.21/mysql-test ; perl mysql-test-run.pl

$ sudo /opt/apps/mysql/bin/mysqld_safe & # 总是启动不成功

查看日志
$ sudo cat /opt/apps/mysql-5.5.21/data/tony-laptop.err
/opt/apps/mysql-5.5.21/bin/mysqld: File './mysql-bin.index' not found (Errcode: 13)
errcode13，一般就是权限问题，mysql用户是否对数据库目录内的所有文件具有写的权限，查看一下权限,发现不对，修改:
$ sudo chown mysql:mysql -R /opt/apps/mysql/data/

再次启动，出现了新的问题:
Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist
$ sudo /opt/apps/mysql-5.5.21/scripts/mysql_install_db --user=mysql \
--basedir=/opt/apps/mysql-5.5.21 \
--datadir=/opt/apps/mysql-5.5.21/data/ \ # 上面我怎么写成了var的权限了，编译的时候，data应该放到var下的
--tmpdir=/opt/tmp/mysql-5.5.21
再次启动就ok了

$ /opt/apps/mysql-5.5.21/bin/mysqladmin -u root password 'new-password' # 设置超级管理密码

$ ln -s /opt/apps/mysql-5.5.21/bin/mysql /usr/bin/mysql # 创建快捷链接

$ mysql -uroot -p # 测试登录

$ sudo mv support-files/mysql.server /etc/init.d/mysql # 设置开机自动启动

$ sudo chmod +x /etc/init.d/mysql # 给与可执行权限

$ sudo /etc/init.d/mysql start # 启动

$ sudo update-rc.d mysql defaults 99 # 开机自动启动
