不能寻路或者启动报错recast 异常断开进不去游戏,检查有没缺失这个文件

1 设置java环境

升级jdk

官网下载jdk-8u202-linux-x64.rpm https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

rpm -ivh /root/jdk-8u202-linux-x64.rpm
wait
sed -r -i '/java|CLASSPATH|JAVA_HOME|LD_LIBRARY_PATH/ s/^/#&/' /etc/profile
echo "#set java environment
JAVA_HOME=/usr/java/jdk1.8.0_202-amd64
CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar
PATH=\$JAVA_HOME/bin:\$PATH
LD_LIBRARY_PATH=/usr/local/lib:\$LD_LIBRARY_PATH
export JAVA_HOME CLASSPATH PATH LD_LIBRARY_PATH" >> /etc/profile
echo -e "\e\033[33m jdk_rpm install ok! \e[0m"
ldconfig
source /etc/profile && java -version

2安装 libzmq v4.3.4

java 环境上一步已配置

首先安装构建zeromq的依赖工具：

yum install libtool gcc gcc-c++ make libuuid-devel autoconf automake
yum -y install git
git clone https://github.com/zeromq/libzmq.git

git境内速度不佳使用 git clone https://github.com.cnpmjs.org/zeromq/libzmq.git

切换目录

cd libzmq/

查看tag

git tag

tag只是快照,检出到本地自定义分支glv4.3.4

git checkout -b glv4.3.5 v4.3.5

查看是否切换成功

git branch

配置、构建、安装、验证：

./autogen.sh
./configure
make -j4 && sudo make install

验证 进入目录

cd /root/libzmq/perf/
./local_lat tcp://127.0.0.1:65432 1 100

打开另一个终端 进入目录

cd /root/libzmq/perf/
./remote_lat tcp://127.0.0.1:65432 1 100

返回 message size: 1 [B] roundtrip count: 100 average latency: 24.860 [us] 表示成功

3安装jzmq (雷同上面)

cd /root/
git clone https://github.com/zeromq/jzmq.git

git境内速度不佳使用 git clone https://github.com.cnpmjs.org/zeromq/jzmq.git

cd jzmq/
git tag

tag只是快照,检出到本地自定义分支jzmq3.1.0

git checkout -b jzmq3.1.0 v3.1.0

查看branch 返回jzmq3.1.0 master

git branch

vim src/main/c++/Event.cpp

编辑Event.cpp ，参考代码对比 https://github.com/zeromq/jzmq/commit/eb40d6db43ce3545e623dad6cc6721a90885b5ba 替换不然make install报错

raw格式查看https://raw.githubusercontent.com/zeromq/jzmq/eb40d6db43ce3545e623dad6cc6721a90885b5ba/src/main/c%2B%2B/Event.cpp 复制 编辑到 src/main/c++/Event.cpp

./autogen.sh
./configure
make -j4 && sudo make install

编译后文件位置

#so文件
#/usr/local/lib
#jar
#/usr/local/share/java/zmq.jar

4 安装dos2unix

yum install -y dos2unix

5 centos7关闭firewalld安装iptables 主要为了兼容centos6游戏服的批量操作

systemctl stop firewalld
systemctl disable firewalld
yum -y install iptables

yum install iptables-services.x86_64 -y
yum -y install bind-utils

安装mysql 能支持mysql mysqldump的后续操作

yum install mysql 

修改open file数量,然后重启生效

echo " 
* soft nofile 65535
* hard nofile 65535
" >>/etc/security/limits.conf
reboot
