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.1 =>(0x00007fff2cbff000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f6a5758a000)
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f6a57353000)
libpcre.so.1 => not found
libz.so.1 => /lib64/libz.so.1 (0x00007f6a56f1f000)
libc.so.6 => /lib64/libc.so.6 (0x00007f6a56b8b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f6a577af000)
libfreebl3.so => /lib64/libfreebl3.so (0x00007f6a56928000)
libdl.so.2 => /lib64/libdl.so.2 (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.1 /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 connection to database 'zabbix' failed: 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
