zabbix server搭建遇到的问题

环境

CentOS 6.3 server

nginx-1.6.3

MySQL-5.6.25

安装nginx遇到的问题

启动nginx时候提示错误“/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory ”

从错误看出是缺少lib文件导致，进一步查看下

ldd $(which /usr/local/nginx/sbin/nginx)

         linux-vdso.so. =>  (0x00007fff2cbff000)

         libpthread.so. => /lib64/libpthread.so. (0x00007f6a5758a000)

         libcrypt.so. => /lib64/libcrypt.so. (0x00007f6a57353000)

         libpcre.so.1 => not found

         libz.so. => /lib64/libz.so. (0x00007f6a56f1f000)

         libc.so. => /lib64/libc.so. (0x00007f6a56b8b000)

         /lib64/ld-linux-x86-.so. (0x00007f6a577af000)

         libfreebl3.so => /lib64/libfreebl3.so (0x00007f6a56928000)

         libdl.so. => /lib64/libdl.so. (0x00007f6a56724000)

可以看出 libpcre.so.1 => not found 并没有找到，进入/lib64目录中手动链接下

cd /lib64/

ln -s /usr/local/lib/libpcre.so. /lib64/ 

nginx启动成功，但是无法访问，关闭防火墙依然无效，

netstat -ntpl 命令查看已经存在nginx进程

kill -9 进程号杀掉，重新启动，成功

安装MySQL时候遇到的问题

提示错误“error: Failed dependencies:

         /usr/bin/perl is needed by MySQL-server-5.6.25-1.linux_glibc2.5.x86_64

         libaio.so.1()(64bit) is needed by MySQL-server-5.6.25-1.linux_glibc2.5.x86_64

         libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.25-1.linux_glibc2.5.x86_64

         libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.25-1.linux_glibc2.5.x86_64”

可以看到缺少libaio库，安装之

yum install libaio

　　　　再次安装，提示“error: Failed dependencies:

         /usr/bin/perl is needed by MySQL-server-5.6.25-1.linux_glibc2.5.x86_64”

缺少perl环境，安装之

yum install perl

安装PHP遇到的问题

错误提示：“Configure: error: xml2-config not found. Please check your libxml2 installation.”

安装libxml2

yum install libxml2 libxml2-devel

错误提示“configure: error: Please reinstall the libcurl distribution -

easy.h should be in <curl-dir>/include/curl/”

安装curl

yum install curl curl-devel

错误提示：“configure: error: jpeglib.h not found.”

安装libjpeg

yum install libjpeg-devel

错误提示：“configure: error: png.h not found.”

安装libpng

yum install libpng-devel

zabbix

登录之后，提示“zabbix server is not running: the information displayed may not be current.”

先去查看日志，根据日志判断是什么问题

如果没有日志，那么试着启动一下

/etc/init.d/zabbix_server start

根据启动提示判断，我遇到的情况是提示“Starting zabbix_server:  /etc/init.d/functions: line 536: /usr/local/sbin/zabbix_server: 没有那个文件或目录”

查看启动脚本发现zabbix_server中的BASEDIR不是zabbix安装路径，改之，解决，可以启动，但还是有问题，但是这时候有日志了，查看日志发现“10950:20150629:160204.156 [Z3001] connection to database 'zabbix' failed: [1045] Access denied for user 'root'@'localhost' (using password: NO)

10950:20150629:160204.156 database is down: reconnecting in 10 seconds”

查看/usr/local/zabbix/etc/zabbix_server.conf配置文件中数据库信息是否正确，改之，正常

启动zabbix时候提示“user zabbix does not exist”

添加zabbix用户

useradd zabbix
