Atlas2.2源码编译安装

432qw

本文主要介绍中间件atlas源码编译安装，由于rpm安装的atlas程序调用时返回的mysql版本为5.0，相应使用低版本的驱动造成时间类型的字段无法支持毫秒级别。

由于需要glib版本要大于2.32以上，centos6系统自带的glib版本为2.28，因此需要重新编译安装2.32以上的glib，这里安装2.34版本的glib需要依赖pcre大于8.31。

一、编译安装pcre8.35

1 2 3

# tar xf pcre-8.35.tar.gz # cd pcre-8.35 # ./configure --prefix=/usr/local/glib--with-pcre=/usr/local/pcre/

二、编译安装glib-2.34.3.tar.xz

1 2 3

# tar xf glib-2.34.3.tar.xz # cd glib-2.34.3 #./configure --prefix=/usr/local/glib --with-pcre=/usr/local/pcre/

三、编译安装Atlas-2.2.1.tar.gz
1.解决依赖关系

1	# yum install libffi-devel lua-devel libeventlibevent-devel

2.修改源码中mysql版本代码，这里mysql版本为5.6.17

1 2 3 4 5

找到plugins/proxy/proxy-plugin.c文件 修改1974行：challenge->server_version_str =g_strdup("5.0.81-log"); 为：challenge->server_version_str= g_strdup("5.6.17-log"); 修改1974行：challenge->server_version = 50081; 为challenge->server_version= 50617;

3.安装atlas

1 2 3 4 5 6 7 8 9 10 11 12 13 14

# tar xf Atlas-2.2.1.tar.gz # cd Atlas-2.2.1 # exportPKG_CONFIG_PATH=/usr/local/glib/lib/pkgconfig # ./configure --with-mysql=/usr/local/mysql5.6/bin/mysql_config--prefix=/usr/local/mysql-proxy LDFLAGS="-lcrypto" # make && make install 或者修改bootstrap.sh #!/bin/sh base=$(cd "$(dirname "$0")"; pwd) cd $base PKG_CONFIG_PATH=/usr/local/glib/lib/pkgconfig ./configure --with-mysql=/usr/local/mysql/bin/mysql_config --prefix=/usr/local/mysql-proxy CPPFLAGS="-I/usr/local/mysql/include/" LDFLAGS="-L/usr/local/mysql/lib/ -lm -ldl -lcrypto" LUA_CFLAGS="-I/usr/include/" LUA_LIBS="-L/usr/lib64 -llua" 执行 # ./bootstrap.sh # make && make install 注意：以上相关程序的头文件和库文件根据自己的环境修改相应的路径

四、启动atlas

1	# /usr/local/mysql-proxy/bin/mysql-proxyd test start

报错
2016-08-0518:05:26: (critical) loading module '/usr/local/mysql-proxy/lib/mysql-proxy/plugins/libproxy.so'failed: libmy
sqlclient.so.18:cannot open shared object file: No such file or directory

2016-08-0518:05:26: (message) shutting down normally, exit code is: 1
解决，导入mysql的库文件到系统

1 2	# echo '/usr/local/mysql/lib/' >> /etc/ld.so.conf # ldconfig

五、atlas升级替换

1.确保待升级的atlas主机操作系统与编译软件的操作系统版本一致

连同编译安装的glib一并部署，同时需要安装依赖关系libffi-devel lua-devel libevent libevent-devel
