MySQL安装方式总结

# 2.1 创建用户与mysql数据存放目录
useradd -M -s /sbin/nologin mysql
mkdir /data
chown mysql.mysql /data
 
# 2.2 安装必要包，下载解压
yum install ncurses-devel -y    #没安装包会有这个报错：checking for termcap functions library... configure: error: No curses/termcap library found
mkdir /home/test   
cd /home/test/tools
wget http://cdn.mysql.com/Downloads/MySQL-5.1/mysql-5.1.73.tar.gz
tar xf mysql-5.1.73.tar.gz
cd mysql-5.1.73
 
# 2.3 生成Makefile，编译，安装
./configure \
--prefix=/application/mysql-5.1.73 \
--with-unix-socket-path=/application/mysql-5.1.73/tmp/mysql.sock \
--localstatedir=/application/mysql-5.1.73/data \
--enable-assembler \
--enable-thread-safe-client \
--with-mysqld-user=mysql \
--with-big-tables \
--without-debug \
--with-pthread \
--enable-assembler \
--with-extra-charsets=complex \
--with-readline \
--with-ssl \
--with-embedded-server \
--enable-local-infile \
--with-plugins=partition,innobase \
--with-mysqld-ldflags=-all-static \
--with-client-ldflags=-all-static
make -j 2 && make install
# 提示：可以通过 echo $? 来查看编译安装过程中是否出错

# 2.4 对mysql-5.1.73创建软连接
ln -s /application/mysql-5.1.73/ /application/mysql

# 2.5 提供配置文件
\cp /application/mysql/share/mysql/my-large.cnf /etc/my.cnf 
#在mysqld中添加    skip_name_resolve =on    innodb_file_per_table = on

# 2.6 初始化mysql
/application/mysql/bin/mysql_install_db --basedir=/application/mysql --datadir=/data/ --user=mysql

# 2.7 提供 SysV 脚本
cp /application/mysql/share/mysql/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
# 修改basedir和datadir
sed -i ‘46s#\(basedir=\).*#\1/application/mysql#‘ /etc/rc.d/init.d/mysqld
sed -i ‘47s#\(datadir=\).*#\1/data#‘ /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld off
chkconfig --list mysqld

# 2.8 启动mysql
/etc/init.d/mysqld start
# 2.9 将mysql的路径加入环境变量
echo "PATH=/application/mysql/bin/:$PATH" > /etc/profile.d/mysql.sh
source /etc/profile.d/mysql.sh 

# 2.10 输出mysql的库文件给系统的查找路径
echo ‘/application/mysql/lib‘ > /etc/ld.so.conf.d/mysql.conf
ldconfig

# 2.11 输出mysql的头文件至系统头文件路径
ln -s /application/mysql/include/mysql/ /usr/include/mysql

# 2.12 将编译的软件man手册加入系统
cat >> /etc/man.config << EOF
# start 20150705 by test
MANPATH /application/mysql/share/man
# end 20150705 by test
EOF
