      今天 360 团队在 GitHub 上发布了 Atlas-2.0.0 版本。可喜可贺,希望 360 的开发团队能够一直保持下去。借此时机,将之前对 Atlas-1.0.3 的一些理解和使用,以博客形式总结一下。本文主要讲一下在源码安装和刚开始运行 Atlas-1.0.3 时可能遇到的问题。

=====

按照安装说明,Atlas-1.0.3 的安装有如下依赖项:
glib(2.32.x)、libevent(1.4以上)、Lua(5.1.x)、OpenSSL(0.9.8以上)

基本执行命令如下:
./bootstrap.sh #可能需要修改其中的路径
make
sudo make install

依赖项的安装不做详细说明,假设已经全部安装好了。

=====

1. 执行   bootstrap.sh
下面是源码包中提供的 bootstrap.sh 脚本的内容:
[root@Betty Atlas-1.0.3]# vi bootstrap.sh 

#!/bin/sh 
base=$(cd "$(dirname "$0")"; pwd)
cd $base
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --with-mysql=/usr --prefix=/usr/local/mysql-proxy CFLAGS="-DHAVE_LUA_H -O2" LDFLAGS="-lm -ldl -lcrypto"
LUA_CFLAGS="-I/usr/local/include/" LUA_LIBS="-L/usr/local/lib -llua"

运行该脚本会报出如下的错误信息:

configure: error: mysql.h is required, please install the mysql header package
[root@Betty Atlas-1.0.3]#

失败原因:找不到 mysql.h 。
解决办法:在 bootstrap.sh 文件中添加 CPPFLAGS="-I/usr/local/mysql/include/"  。

修改后 bootstrap.sh  文件如下:
[root@Betty Atlas-1.0.3]# vi bootstrap.sh  

#!/bin/sh 
base=$(cd "$(dirname "$0")"; pwd)
cd $base
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --with-mysql=/usr --prefix=/usr/local/mysql-proxy CFLAGS="-DHAVE_LUA_H -O2" CPPFLAGS="-I/usr/local/mysql/include/" LDFLAGS="-lm -ldl -lcrypto" LUA_CFLAGS="-I/usr/local/include/" LUA_LIBS="-L/usr/local/lib -llua"

重新执行 bootstrap.sh 成功(即执行常规操作中的 configure )。

2. 执行 make
[root@Betty Atlas-1.0.3]# make
...
libtool: link: gcc -shared  .libs/libproxy_la-proxy-plugin.o   -Wl,-rpath -Wl,/root/workstation/mnt/Atlas-1.0.3/src/.libs -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/mysql-proxy/lib -Wl,-rpath -Wl,/usr/local/lib -L/root/workstation/mnt/Atlas-1.0.3/src/.libs -L/usr/local/lib -L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -L/usr/lib64 -lssl ../../src/.libs/libmysql-proxy.so /root/workstation/mnt/Atlas-1.0.3/src/.libs/libmysql-chassis.so ../../src/.libs/libsql-tokenizer.so /usr/local/lib/libevent.so -lnsl -lresolv -llua /usr/local/lib/libgmodule-2.0.so /usr/local/lib/libgthread-2.0.so /root/workstation/mnt/Atlas-1.0.3/src/.libs/libmysql-chassis-timing.so /root/workstation/mnt/Atlas-1.0.3/src/.libs/libmysql-chassis-glibext.so -lm -ldl -lcrypto /usr/local/lib/libglib-2.0.so -lpthread -lrt  -Wl,--export-dynamic -pthread   -pthread -Wl,-soname -Wl,libproxy.so -o .libs/libproxy.so

make[3]: *** [libproxy.la] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/workstation/mnt/Atlas-1.0.3'
make: *** [all] Error 2
[root@Betty Atlas-1.0.3]#

失败原因:找不到 mysqlclient 库。
解决办法:在 bootstrap.sh 文件中修改 LDFLAGS 的内容,添加 "-L/usr/local/mysql/lib/" 。

修改后  bootstrap.sh  文件如下:
[root@Betty Atlas-1.0.3]# vi bootstrap.sh 

#!/bin/sh 
base=$(cd "$(dirname "$0")"; pwd)
cd $base
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --with-mysql=/usr --prefix=/usr/local/mysql-proxy CFLAGS="-DHAVE_LUA_H -O2" CPPFLAGS="-I/usr/local/mysql
/include/" LDFLAGS="-L/usr/local/mysql/lib/ -lm -ldl -lcrypto" LUA_CFLAGS="-I/usr/local/include/" LUA_LIBS="-L/usr/local/lib -llua"

重新 bootstrap.sh && make 成功。

3. 执行 make install
[root@Betty Atlas-1.0.3]# make install
Making install in src
make[1]: Entering directory `/root/workstation/mnt/Atlas-1.0.3/src'
make  install-am installdirs installscript
make[2]: Entering directory `/root/workstation/mnt/Atlas-1.0.3/src'
/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..  -I/usr/include/mysql  -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include   -I/usr/local/include/ -pthread -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include   -pthread -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include   -I../lib/ -I/usr/local/mysql/include/  -DHAVE_LUA_H -O2 -MT libsql_tokenizer_la-sql-tokenizer-keywords.lo -MD -MP -MF .deps/libsql_tokenizer_la-sql-tokenizer-keywords.Tpo -c -o libsql_tokenizer_la-sql-tokenizer-keywords.lo `test -f '../lib/sql-tokenizer-keywords.c' || echo './'`../lib/sql-tokenizer-keywords.c
...
test -z "/usr/local/mysql-proxy/lib/pkgconfig" || /bin/mkdir -p "/usr/local/mysql-proxy/lib/pkgconfig"
 /usr/bin/install -c -m 644 mysql-proxy.pc mysql-chassis.pc '/usr/local/mysql-proxy/lib/pkgconfig'
make[2]: Leaving directory `/root/workstation/mnt/Atlas-1.0.3'
make[1]: Leaving directory `/root/workstation/mnt/Atlas-1.0.3'
[root@Betty Atlas-1.0.3]#

执行成功。

      此时你会发现,可执行程序 mysql-proxy 和 shell 脚本 mysql-proxyd 并没有安装到系统的标准可执行文件所在目录。可以通过在环境变量 PATH 中添加的方式进行解决。

4. 运行可执行程序 mysql-proxy
      尝试执行 mysql-proxy 看有什么输出(以下给出的 log 信息中存在本人添加的调试打印,故与原代码略有差异)。
[root@Betty ~]# mysql-proxy
2013-11-25 14:41:59: (debug) chassis-stats.c:35: created new global chassis stats at 0x41a3f40
2013-11-25 14:41:59: (debug) chassis-timings.c:124: created new global chassis timer info at 0x41a4dd0
2013-11-25 14:41:59: (debug) mysql-proxy-cli.c:329: [MoDB] print_version = 0    default_file = (NULL)
2013-11-25 14:41:59: (debug) mysql-proxy-cli.c:432: [MoDB] base_dir = /usr/local/mysql-proxy
2013-11-25 14:41:59: (critical) chassis-frontend.c:122: Failed to get log directory, please set by --log-path
2013-11-25 14:41:59: (message) Initiating shutdown, requested from mysql-proxy-cli.c:443
2013-11-25 14:41:59: (message) shutting down normally, exit code is: 1
[root@Betty ~]#

      出现一条 critical 日志,大致意思是“无法找到保存日志文件的路径位置,需要通过 --log-path 进行指定”。而执行 mysql-proxyd 脚本得到输出如下:

[root@Betty ~]# mysql-proxyd 
Usage: /usr/local/mysql-proxy/bin/mysql-proxyd instance {start|stop|restart|status}

      综上,想要运行起来 Atlas-1.0.3 ,至少要了解如何设置日志目录,以及 instance 所代表的含义。查看 GitHub 上的信息,发现可以通过自定义配置文件解决这两个问题。我的测试配置文件如下:

[mysql-proxy]

plugins = admin, proxy

admin-username = moooofly
admin-password = moooofly
admin-lua-script = /usr/local/mysql-proxy/lib/mysql-proxy/lua/admin.lua

proxy-backend-addresses = 127.0.0.1:3306
#proxy-read-only-backend-addresses = 127.0.0.1:3305@1

daemon = true
keepalive = true

event-threads = 4

log-level = debug
log-path = /usr/local/mysql-proxy/log

instance = modb

proxy-address = 0.0.0.0:1234
admin-address = 0.0.0.0:2345

min-idle-connections = 128

#tables = person.mt.id.3
#pwds = user1:+jKsgB3YAG8=, user2:GS+tr4TPgqc=

charset = utf8

#client-ips = 127.0.0.1, 192.168.1
#lvs-ips = 192.168.1.1

      上述配置中,很多选项目前不需要启用,所以都注释掉了。唯一需要说明的是,Atlas-1.0.3 对配置文件的名字有如下约束:要求配置文件名字和配置文件中的 instance 的名字要保持一致。例如我的配置文件名字为 modb.cnf ,所以 instance 的名字为 modb 。

      重新使用 mysql-proxyd 脚本启动服务程序,输出信息如下:
[root@Betty ~]# mysql-proxyd modb status
MySQL-Proxy of modb is NOT running
[root@Betty ~]# mysql-proxyd modb start
OK: MySQL-Proxy of modb is started
[root@Betty ~]# mysql-proxyd modb status
MySQL-Proxy of modb is running (7186)
MySQL-Proxy of modb is running (7187)
[root@Betty ~]# ps aux|grep mysql-proxy
root      7186  0.0  0.0  57960  1028 ?        S    14:54   0:00 /usr/local/mysql-proxy/bin/mysql-proxy --defaults-file=/usr/local/mysql-proxy/conf/modb.cnf
root      7187  0.0  0.0 111524  2356 ?        Sl   14:54   0:00 /usr/local/mysql-proxy/bin/mysql-proxy --defaults-file=/usr/local/mysql-proxy/conf/modb.cnf
root      7207  0.0  0.0  61180   752 pts/4    S+   14:54   0:00 grep mysql-proxy
[root@Betty ~]#

      可以看出,服务器程序已经正确启动。此时在 log 目录下会多出如下文件:

[root@Betty log]# pwd
/usr/local/mysql-proxy/log
[root@Betty log]# 
[root@Betty log]# ll
总计 8
-rw-r----- 1 root root 1233 11-25 14:54 modb.log
-rw------- 1 root root    4 11-25 14:54 modb.pid
-rw-rw-rw- 1 root root    0 11-25 14:54 sql_modb.log
[root@Betty log]#

      其中 modb.log 是服务器的通用日志;sql_modb.log 是经由 Atlas 进行处理、转发的 sql 日志。
启动 Atlas 时 modb.log 中的日志内容:

[root@Betty log]# tail -f modb.log 
2013-11-25 14:54:06: (message) mysql-proxy 0.8.2 started - instance: modb

      通过 MySQL 客户端经由 Atlas 访问 MySQL 数据库时,sql_modb.log 中的日志内容:

[root@Betty log]# tail -f sql_modb.log

至此,一个 源码安装 的、可用的、 具有基本配置 的 Atlas-1.0.3 完成了。
