CentOS 7.6 下MySQL 8.0.16编译安装
1.最小化安装CentOS 7.6系统
2.安装基础包
yum -y install ntpdate gcc gcc-c++ ncurses ncurses-devel cmake readline-devel zlib.x86_64 zlib-devel.x86_64 bison libcurl-* net-tool* tree nmap sysstat lrzsz dos2unix telnet.x86_64 nethogs iftop iotop unzip ftp.x86_
64 xfs* expect vim wget psmisc openssh-client* libaio libaio1 libnuma openssl-devel bzip2
3.基础环境配置
systemctl stop firewalld
systemctl disabled firewalld
systemctl stop postfix
systemctl disable postfix
sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config && cat /etc/selinux/config >> ${tmplog_dir}/base.log 2>&1
setenforce 0
getenforce
4.内核参数修改
echo "vm.swappiness=10">>/etc/sysctl.conf
echo "net.ipv4.tcp_tw_recycle=1">>/etc/sysctl.conf
echo "net.ipv4.tcp_tw_reuse=1">>/etc/sysctl.conf
echo "vm.dirty_background_ratio=8">>/etc/sysctl.conf
echo "* soft nofile 1024000" >>/etc/security/limits.conf
echo "* hard nofile 1024000" >>/etc/security/limits.conf
数据盘挂挂载参数
rw,noatime,nodiratime,nobarrier
5.升级gcc
mkdir /usr/local/tools && cd /usr/local/tools
wget http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-5.5.0/gcc-5.5.0.tar.xz
tar xf gcc-5.5.0.tar.xz
cd gcc-5.5.0
./contrib/download_prerequisites
mkdir build && cd build
../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
make && make install
6.升级cmake
建议另外开一个session防止环境变量未生效
cd /usr/local/tools
wget https://github.com/Kitware/CMake/releases/download/v3.14.5/cmake-3.14.5.tar.Z
./bootstrap
make && make install
如果出现以下错误
ibstdc++.so.6: version `CXXABI_1.3.9' not found (required by ./destructor)
处理如下：
find / -name "libstdc++.so*"
mv /usr/lib64/libstdc++.so.6.0.21 /tmp/
cp /usr/local/tools/gcc-5.5.0/build/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.21 /usr/lib64/
mv /usr/lib64/libstdc++.so.6 /tmp/
ln -s libstdc++.so.6.0.21 libstdc++.so.6
7.编译安装Mysql
cd /usr/local/tools
tar xf mysql-boost-8.0.16.tar.gz
cd mysql-8.0.16
cmake . \
-DWITH_BOOST=/usr/local/tools/mysql-8.0.16/boost/boost_1_69_0 \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql3306/data \
-DWITHOUT_CSV_STORAGE_ENGINE=1 \
-DWITHOUT_FEDERATED_STORAGE_ENGINE=1 \
-DWITHOUT_ARCHIVE_STORAGE_ENGINE=1 \
-DFORCE_INSOURCE_BUILD=1 \
-DWITH_SSL=system \
-DCMAKE_CXX_COMPILER=/usr/local/bin/g++ \
-DCMAKE_C_COMPILER=/usr/local/bin/gcc
make -j 8
make install

9.初始化数据库
mkdir -pv /data/{mysql3306/{data,logs,tmp},conf,scripts,dumpdir}
/usr/local/mysql/bin/mysqld --defaults-file=/data/conf/my3306.cnf --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3306/data
10.配置启动脚本
#!/bin/sh
port="3306"
my_lp="3306_system"
mysql_bin="/usr/local/mysql/bin/"
mysql_sock="/data/mysql${port}/data/mysql.sock"
config_file="/data/conf/my3306.cnf"
#start Mysql Services
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL_3306 ...\n"
/bin/sh ${mysql_bin}/mysqld_safe --defaults-file=${config_file} 2>&1 > /dev/null &
else
printf "MySQL_3306 is running...\n"
exit
fi
}
#stop Mysql Services
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL_3306 is stopped...\n"
exit
else
printf "Stoping MySQL_3306...\n"
${mysql_bin}/mysqladmin --login-path=${my_lp} -S ${mysql_sock} shutdown
fi
}
#restart Mysql Services
function_restart_mysql()

sleep 2

}
case $1 in
start)

;;
stop)

;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/scripts/mysql3306 {start|stop|restart}\n"
esac
chmod a+x /data/scripts/mysql3306
11.启动服务
/data/scripts/mysql3306 start
12.修改密码
mysql -uroot -p -S /data/mysql3306/data/mysql.sock
alter user user() identified by "netdata";
13.设置login-path
mysql_config_editor set --login-path=3306_root -uroot -p -S /data/mysql3306/data/mysql.sock
14.设置环境变量
echo "alias mysql3306='mysql --login-path=3306_root --defaults-file=/data/conf/my3306.cnf --default-character-set=utf8mb4'
">>~/.bashrc
source ~/.bashrc
