安装MySQL

编译前配置

export CXXFLAGS="-std=c++98 -D_GLIBCXX_USE_CXX11_ABI=0 -fpermissive -Wno-narrowing"

./configure \
    --prefix=/usr/local/mysql \
    --enable-thread-safe-client \
    --with-charset=gbk \
    --with-collation=gbk_chinese_ci \
    --with-extra-charsets=all \
    --enable-shared \
    --with-fast-mutexes \
    --with-plugins=max-no-ndb \
    --with-ssl \
    --with-libwrap \
    --with-mysqld-libs="-lrt -lpthread" \
    --with-zlib=system \
    --with-big-tables

字符集参数说明

--with-charset=gbk                  # 默认字符集设为GBK
--with-collation=gbk_chinese_ci      # 中文默认排序规则

--with-charset=latin1               # 原始万能字符参数
--with-collation=latin1_general_ci   # 万能字符默认排序规则

编译安装

make -j4
make install

数据库配置

基础配置

1. 创建数据库用户组

   groupadd mysql && useradd -g mysql mysql

2. 创建所需目录

   mkdir -p /usr/local/mysql/{data,run,log,var}

3. 设置目录权限

   chgrp mysql -R /usr/local/mysql

4. 设置文件打开限制

   ulimit -n 4096

5. 添加环境变量

   echo "PATH=\"/usr/local/mysql/bin:\$PATH\"" >> /etc/profile
   export PATH="/usr/local/mysql/bin:$PATH"

配置文件设置

1. 拷贝配置文件

   cp support-files/my-huge.cnf /etc/my.cnf

2. 编辑配置文件

   vi /etc/my.cnf

   添加以下内容：

   datadir=/usr/local/mysql/data
   skip-name-resolve  # 解决连接慢问题

3. 设置数据目录权限

   chown mysql.mysql /usr/local/mysql/data -R

数据库初始化

su - mysql -c "mysql_install_db"
su - mysql -c "mysqld_safe --skip-name-resolve --open-files-limit=4096&"

数据库管理

基本操作

1. 登录MySQL

   mysql

2. 查看数据库

   show databases;

3. 查看字符集

   show variables like '%character%';

权限配置

-- 本地访问授权
GRANT ALL PRIVILEGES ON *.* TO ztgame@"localhost" IDENTIFIED BY "123456" WITH GRANT OPTION;

-- 回环地址授权
GRANT ALL PRIVILEGES ON *.* TO ztgame@"127.0.0.1" IDENTIFIED BY "123456" WITH GRANT OPTION;

-- 远程访问授权
GRANT ALL PRIVILEGES ON *.* TO ztgame@"%" IDENTIFIED BY "123456" WITH GRANT OPTION;

-- 刷新权限
FLUSH PRIVILEGES;

创建数据库

CREATE DATABASE FLServerDB;
CREATE DATABASE ZtGameDB;
CREATE DATABASE LoginServer;
CREATE DATABASE roleChangeServer;
CREATE DATABASE roleregServer;
CREATE DATABASE unify00;
CREATE DATABASE zt;

服务管理

开机启动设置

cp support-files/mysql.server /etc/init.d/mysqld
chmod -R 777 /etc/init.d/mysqld
/etc/init.d/mysqld start
chkconfig --add mysqld
chkconfig mysqld on

服务管理

开机启动设置（系统差异）

1. Systemd系统（RHEL 8+/Rocky 8+/Debian 9+/Ubuntu 16.04+）

# 创建systemd服务文件
cat > /etc/systemd/system/mysqld.service <<EOF
[Unit]
Description=MySQL Server
After=network.target

[Service]
User=mysql
Group=mysql
ExecStart=/usr/local/mysql/bin/mysqld_safe
Restart=always
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target
EOF

# 启用服务
systemctl daemon-reload
systemctl enable mysqld
systemctl start mysqld

2. SysVinit系统（CentOS 7/RHEL 7）

cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
service mysqld start

3. Debian系update-rc.d

cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
update-rc.d mysqld defaults
service mysqld start

临时目录创建

mkdir /tmp/offlineMessages
